My doctor actually recommended Wheat Belly, or I wouldn't have picked it up. Cure Your Child With Food, for instance, already mentions that gluten, the protein in wheat, is the source of many digestion problems. That book reported loads of success curing kids by eliminating wheat and anything white from their diets.
The Wheat Belly proceeds to blame almost all modern ills on wheat and wheat products. As in Cure Your Child With Food, he claims that wheat has been so genetically engineered or otherwise manipulated that the nutrition in it is not something that your body can absorb or deal with, leading to a bunch of diseases ranging from diabetes to acne (!!) to early balding in men. The book is replete with anecdotes from his practice where the patient is miraculously cured after eliminating wheat from his or her diet.
Unfortunately, things are not that simple. You see, Doctor Davis doesn't just recommend getting rid of wheat. He recommends eliminating all forms of whole grain and potatoes as well as the sugary fruits. Adopt his program wholesale and what do you get? The Atkins diet. If wheat was the all encompassing evil he claims it to be, then there shouldn't be any need to eliminate all the other foods, so this prescription basically undermines the entire first 2/3rds of the book!
Now, it could very well be that gluten sensitivity (not necessarily celiac disease) is far more prevalent than you might think, and that many people with irritable bowel syndrome could benefit by eliminating wheat. But if you're looking for proof that wheat is the culprit, then this book definitely does not provide it. That said, he does reference lots of interesting data, including Denise Minger's excellent debunking of the China Study. There's a lot of interesting information, though again, since he undermined himself in the last 2 chapters of the book I'm not sure how much I'd be willing to believe anything he says.
Not recommended.

Review: Pyle Waterproof MP3 Player with embedded headphones
I've been forced to swim a lot recently, and have come to the conclusion that lap swimming is the most boring sport in the universe. There's nothing to see, the scenery doesn't change, and you can't even hold a conversation while swimming like you can while you're cycling, running, or doing almost any land sport. I can't imagine doing it for any length of time long term.
After a while, I decided that it would be a good idea to find someway of listening to something while I'm doing my boring laps. If you're an iSheep, then the natural thing would be to pick up the Underwater iPod. These are basically iPod shuffles have been rebuilt with a waterproof resin internally and a waterproof coating externally, and then you can fit a pair of waterproof headphones to them, attach the whole shebang to your googles, and now you have an iPod that can play music underwater.
But I'm not an Apple fan, and $150 for a 2GB iPod shuffle is incredibly offensive to my senses. So I went looking and came up with the Pyle Waterproof MP3 player. At $40, it's more expensive than some other products, but it also had far better Amazon reviews. At 4GB of storage, it's got twice the storage of the Apple equivalents at one third the price, something very familiar to anyone who's familiar with how tech pricing works.
My first couple of swims were disappointing. The sound was muddy and unclear, and the headphone kept coming off. But I finally figured it out: the headphones come with 3 sets of ear pieces for underwater use, and what you need to do is to use the biggest ear piece that will fit in your ear canal. Once I got the right set (which surprisingly was the largest set), the sound was clear and lovely, and the ear pieces don't try to come off your ear. Now, if you do a particularly violent motion or if you knock your headphones with your strokes you still might get some leakage, but by and large the whole thing works and seriously, once I stop needing to nurse my back along I'm not going to swim more than a couple of times a week anyway.
In any case, my swims have gotten a lot less boring, and more than once I've found myself swimming an extra couple of laps to finish the song I've been listening to, so it's definitely changed lap swimming from "boring" to bearable. Recommended.

Review: The Story of The Human Body
The Story Of The Human Body is written by evolutionary biologist and Harvard Professor Daniel Lieberman. It's not just a boring history of how your various body parts evolved, but it's also an exploration about how mismatch diseases come about: diseases caused by the mismatch between your relatively old genes and the relatively unusual state of civilization today.
Midway through the book (page 173), there's a list of mismatch diseases that hold a few surprises even for me. For instance, apnea, ADHD, OCD, and chronic constipation are all considered to be mismatch diseases. I'm very familiar with Apnea, and I was surprised to find it on this list. The explanation is surprising: if you grew up on relatively soft processed or cooked food, you didn't have to chew very much or very hard, so your jaw ends up being a bit too small, which is one of the conditions that causes apnea. Lieberman suggests allowing kids to chew gum a lot as a way to help correct this deficiency, and I wonder if Singapore's ban on chewing gum could contribute to a rise in the number of children who end up with sleep apnea in the future as a result.
Which brings me to another interesting point about this book. Because mismatch diseases have long lead times and are caused by conditions in which the child grows up in, but the disease itself doesn't show up until in late adulthood, this book also doubles as a parenting manual of things that you as a parent should do, but might not have realized are important. For instance, he suggests letting kids run around in bare feet as much as possible to prevent future incidences of flat feet. This goes against the norms of civilized society, and parents should take note. Other little tit-bits from this book:
Lieberman ties off the book with a bunch of policy suggestions as to how to prevent many of the mismatch diseases he describes. I have a very pessimistic outlook on those suggestions, as the long feedback cycle (40 years or so before diabetes begins to show up) ensures that much like global climate change, there's no real incentive for government to do anything about it.
I thoroughly enjoyed this book and found it incredibly informative. It's very likely to be the best book I've read all year. Highly recommended.

- Growing up in a hot environment will cause your child to develop more sweat glands. This may or may not be a good thing, depending on your point of view.
- Baby fat is not necessarily benign: even if the kid grows out of it, being fat at a young age causes your body to have more visceral fat cells, which can lead to being more easily fat as an adult.
- Myopia could be caused by spending too much time indoors, and insufficient variety of visual stimuli. Having a wide variety of visual stimulus is important for normal vision.
- If your kids get antibiotics, it might be necessary to follow up with a dose of probiotics to help the stomach flora return to normal.
- Sitting is very bad for you.
- Human beings are basically the fattest primates around, but there are good reasons why.
- Why do men get prostate cancer?
- Why do you tend to get back pain as you age?

Review: Skating to where the puck was
Skating to Where the Puck Was is part of William Bernstein's series called "Investing for Adults". I did not consider the previous book I read in the series, Deep Risk, to be worth the trouble, but I have a different opinion of this book.
The book repeats stuff you probably already know as an investing adult, but the stories inside are worth a quick read and the book is cheap. Recommended.
Bernstein points out that in many cases, by the time an asset class is widely accessible to the masses for investing, it has lost most of the attractive properties it used to have, therefore rendering the asset class much less interesting. The first example he uses is from David Swensen's Pioneering Portfolio Management: the Yale Model, with its reliance of alternative assets, including hedge funds and other such, returned outsized success until it became widely known and copies, at which point it stopped yielding those outsized returns.
Similarly, he points out that recently, an individual investor could make outsized gains in the housing market by buying up houses and renting them for profit, but doing so would have required that you make a full time job (or serious side job) out of it, not by merely investing in an REIT. Similarly, the Japanese stock market returned incredibly high yields when John Templeton bought into it very early. So early, in fact, that when he first bought shares in the market, they could not even be taken out of the country! By the time generalized Japanese stock funds became available, the return on those funds going forward was dismal. The result, Bernstein says, is that:
if your portfolio looks like the Yale Endowment's, then you're likely to find yourself chairless when the music stops. Diversifying is easy; doing so early is difficult.The solution? Boring old asset allocation and staying in the market for the long haul. There a really is no Santa Claus, and no tooth fairy, unless you're the next John Templeton and have the courage to get in ahead of the crowd. (And even then, there's no guarantee that you're not the next Bill Miller instead)
The book repeats stuff you probably already know as an investing adult, but the stories inside are worth a quick read and the book is cheap. Recommended.

Review: 3M Command Strips
I never really was into hanging photos or artwork on the walls, even photos I took myself. It wasn't until recently that I figured out what. It turns out that nailing holes in the wall is a somewhat permanent act, and I didn't like the irrevocability of putting a photo up.
One of the helpful folks at Orchard Supply inadvertently pointed that out to me when I asked about buying hanging fixtures. Thinking that I rented an apartment, he told me about 3M Command Strips, which are essentially matching sets of Velcro backed by sticky tape. The clever thing about the Command Strips is that there's a tab on the back of the sticky tape which stretches the glue in the sticky tape so that the entire strip comes cleanly off the wall when done.
A few things are necessary to get these to work right. First, you should use them only as recommended for their weight ratings. Secondly, you need the surfaces to be clean. Lastly, you actually have to follow the directions. We've hung a mirror and 2 pictures with these trips, and I'm very happy with them. I haven't actually tested the removal, but judging from the Amazon reviews, that's not actually a problem.

Review: Cure Your Child With Food
Cure Your Child With Food is a book about nutrition and the impact nutrition has on children's health and growth. It's an interesting book in that it's organized with each chapter meant to be read independently, which leads to a lot of repetition.
For instance, my impression of the first half of the book is that she's a one-trick pony. She seemed to have only two solutions for the patients who come to her: get rid of the diary in the diet, and ditch the gluten. Get rid of the American "white diet". That's it.
The second half of the book, however, does demonstrate that she doesn't just prescribe one thing for all patients. For instance, one patient came to her with sleep problems and an otherwise healthy diet. Getting her onto 0.5mg of melatonin supplement an hour before bedtime meant she could sleep through the night. She explains why melatonin is a good solution and why it is not addictive. Another patient came to her from a vegetarian background with muscular development issues. Adding choline and fish oil to his diet resolved his issues. She does caution that sometime fish oil by itself isn't enough and that other forms of intervention are required. She diagnosed one case of a patient ingesting pesticide from fruit.
She presents interesting theories about why there's been a recent rise in gluten sensitivity (not the same as celiac disease): the amount of gluten in wheat that has been harvested has gone up, due to "improved breeding" and other interventions. She also explains why she recommends fish oil supplements over just adding more fish to the diet: the risk of mercury poisoning.
While the book is wordy and repetitive, I found it useful in thinking about children's nutrition. For instance, once you take your kid off infant formula, you should think about where his Omega-3 is going to come from. In our case, it was more palliative than anything else, but it's not quite a "one trick pony" book that the first half of the book presents itself to be. Recommended.

Advanced Reader Copies of my next book now available
It's called How to Interview A Financial Advisor. It's a short book, about 50 pages, and the first round of beta only has 20 copies available. Since it's currently in beta, it doesn't have a cover yet (I'm waiting for the cover to come in), and the PDF copy doesn't have an index. If you make comments about the book that lead to changes in the book, you'll get to be on the acknowledgements page.
The book is priced low $4.95, and I'm still trying to decide on the final pricing. As a perk, beta customers will also get cheap access to the printed copy when it is finally available.

Review: Aqua Sphere Kayenne Goggle
I've been suffering from some lower back pain due to lifting my toddler at a time when he was struggling. The pain's been bad enough that I've been banned from cycling or heavy lifting, and about the only sport I can indulge in is swimming.
I've been stealing my wife's cheap goggles for those swims, but they're a bit small for me (yes, I know, you're not surprised), and I felt the pressure in my eyes. They also weren't optically very clear, so I splurged and bought the Aqua Sphere Kayenne Googles.
I picked these because (1) they're cheap, and (2) the goggles themselves are wide enough that it looked like the cup around the goggles would be wide enough so that they would spread themselves out over a wide area around my eyes, relieving some of the pressure around my eyes while swimming. At $16 for the cheapest versions they're not super cheap, but they were indeed less pressure than the previous goggles.
They're also optically very clear! I swapped them with my wife one day in the pool and she liked it so much I bought her another pair that were identical to mine. Needless to say, for me to buy 2 of anything means I really like it alot. Recommended.

Review: Invisiblity
Invisibility is a young-adult novel by Andrea Creme and David Levithan. Levithan, you'll recall, is the author of Every Day, and the voice in this novel is very similar to that novel, despite being told alternatively from two perspectives, Stephen and Elizabeth.
The hook in the novel is that Stephen was cursed to be invisible from the day he was born. The novel details all the issues this brings. Stephen seems to have done a good job coping with life as it is, until one day, neighbors move in and Elizabeth is able to see him. We start with a quiet love story, set in New York and its environs, while Elizabeth and Stephen work through their budding romance.
Once Elizabeth discovers that she's the only person who can see Stephen, however, the action revs up and the novel goes into high gear. She quickly discovers why, and starts trying to figure out ways to solve Stephen's problem. At this point, Stephen quickly shifts from being the center of the story to becoming almost a by-stander.
What I like about the novel is that the characters are faced with no easy answers, and have to sacrifice in order to stay together. The authors also do not try to resolve the situation arbitrarily and let the rules they have in place run the climax and conclusion.
While this novel started slowly, towards the end I found myself captivated, flipping pages relentlessly to find out what happens next. That the novel doesn't cheat itself by trying to set up for a sequel (unlike Every Day) is another point in its favor.

Review: Six Earlier Days
Six Earlier Days is a short prequel to David Leviathan's novel, Every Day. It's a light fast read, but doesn't have the heft or development of the novel. It brings together 6 different days of A's life, some of which reveals a facet of his character, and two of which foreshadowing the events to come in the novel. I can only recommend this book if you read Every Day and wanted more.
Review: Deep Risk
William Bernstein has written a new series of short books titled "investing for adults". Deep Risk is one of the series. The book is short, and I wish Bernstein had simply cobbled all the books in the series together as one book rather than trying to sell each monograph separately.
The idea behind Deep Risk is that there are 4 major potential disasters (Bernstein refers to them as the Four Horsemen) that can derail your financial plan. These are: inflation, deflation, confiscation (taxes), and devastation (war). He then analyzes them in terms of how frequently they occur and how difficult it would be to insure against them.
It shouldn't surprise anyone that inflation is by far the most common potential problem for any portfolio. What's interesting about Bernstein's analysis is that he discovers that the traditional inflation protection, Gold bullion, isn't actually very good as an inflation hedge! Rather, stock portfolios tend to do far better as inflation protection even though in the aftermath of an inflation, the stocks could do badly. Bernstein dismisses the potential short term underperformance of stocks as shallow risk: in other words, if you had the fortitude to hang on, you'd recover your portfolio with no permanent loss of capital.
Deflation is much less likely, and Bernstein claims that it has only happened once in Japan since developed countries went off the gold standard. He dismisses Japan as a one off. I disagree, as the U.S. came close to adopting the very same policies that Europe did and could have gotten 10 years of deflation as well. It's also not clear to me that Europe hasn't been subject to the same deflationary problems. Bernstein claims that gold is actually a great deflation hedge, since a big depression triggers a flight to safety, which is what gold traditionally is.
Bernstein defines confiscation relatively loosely. For instance, an increase in tax rates could be defined as confiscation. It seems to me that you could solve the confiscation relatively easily, by moving to a very high tax state with already confiscatory taxes, at which point your risk of further confiscation is relatively low. To be fair, Bernstein does point out the exiting U.S. citizenship would cost you an exit tax, and even holding foreign assets is no protection from the tax man, should we ever get an administration that chooses to enforce such laws. The reality is, if you're a U.S. citizen intending to stay in the U.S., there's relatively little that you can do beyond the existing well-known tax-sheltered accounts and tax-managed funds.
Finally, the threat of war is real, but again, there's relatively little you can do unless you decide to become a survivalist and start building bunkers. In serious threats, what you'd have to do is to stockpile food, guns, and ammunition and build a private army. Historically, people who've done that don't tend to do all that well financially, and the existence of events such as the Waco Seige indicates that even building your own private army doesn't do very good if someone with a real army chose to take you out.
Ultimately, I found the entire book disappointing and lacking in useful action items. The truth is, as a financial observer I've found that far more people have devastated their portfolio by panicking during a crisis than by having their wealth confiscated by a government, war, or even inflation. So rather than writing a series of books called "investing for adults", Bernstein probably should have written a book about how to become an adult, as far as investing is concerned. Not recommended.

Review: The Sports Gene
The Sports Gene is not just a book about athletes. It's also a thorough debunking of books such as Talent is Overrated. If you were to want to debunk that book, you'd want to do this starting with athletes. Pretty much everyone knows intuitively that no on 5' 2" and shorter is going to play in the NBA. The disadvantages that accrue from being shorter than all the freaks of nature playing in the NBA would just be too much for any amount of practice to overcome.
The book starts with Tiger Woods, whose dedication to golf is pretty famous and well-documented. What Epstein points out, however, is that few accounts of Woods' success points out that even at 6 months, Woods was capable of standing on his father's palm while his dad walked around the house! That's innate talent that wasn't taught and can't be taught.
The book then goes on to cover short distance athletes, marathoners, skiers, sled dogs, and ties it all together. What's great is that in the course of covering the genetics of performance, he also discusses certain questions that have always bothered me. For instance, if living at altitude is so beneficial, why aren't the gold medalist sprinters and marathoners from Tibet and the Nepal Himalaya instead of being from Africa? It turns out that there's an optimum altitude for hemoglobin creation (5000-7000'), beyond which it's difficult to train hard. Furthermore, the sherpas and other high mountain people developed a different genetic pathway towards altitude acclimation rather than the metabolically expensive hemoglobin creation.
There's also a great discussion of Superbaby, how the success of a breed of alaskan Huskies proved that even motivation has a genetic component (they bred a breed of dogs that just wants to run when harnessed!).
The author also studied the Australian Olympic program, which specializes in identifying which sports an athlete is uniquely suited for, and then grooms that athlete for those sports. In those cases, it's quite clear that gold medalists with talent can achieve in 4,000 hours what others without talent cannot do with 10,000 hours.
Epstein succeeds in making his points, though obviously doesn't answer any questions about the intellectual analogues to the skills/abilities he discusses. Along the way, you'll learn a few things about genetics and what types of bodies it takes to succeed in the various sports. The average reader might be disappointed that he doesn't discuss what ethical implications they may be, and how quickly genetic engineering is likely going to take over the sporting events. The days of unaugmented athletes being able to perform at the world level might very well be numbered.
I thoroughly enjoyed the book, and can highly recommend it.

What's great is that in the course of covering the genetics of performance, he also discusses certain questions that have always bothered me. For instance, if living at altitude is so beneficial, why aren't the gold medalist sprinters and marathoners from Tibet and the Nepal Himalaya instead of being from Africa? It turns out that there's an optimum altitude for hemoglobin creation (5000-7000'), beyond which it's difficult to train hard. Furthermore, the sherpas and other high mountain people developed a different genetic pathway towards altitude acclimation rather than the metabolically expensive hemoglobin creation.
There's also a great discussion of Superbaby, how the success of a breed of alaskan Huskies proved that even motivation has a genetic component (they bred a breed of dogs that just wants to run when harnessed!).
The author also studied the Australian Olympic program, which specializes in identifying which sports an athlete is uniquely suited for, and then grooms that athlete for those sports. In those cases, it's quite clear that gold medalists with talent can achieve in 4,000 hours what others without talent cannot do with 10,000 hours.
Epstein succeeds in making his points, though obviously doesn't answer any questions about the intellectual analogues to the skills/abilities he discusses. Along the way, you'll learn a few things about genetics and what types of bodies it takes to succeed in the various sports. The average reader might be disappointed that he doesn't discuss what ethical implications they may be, and how quickly genetic engineering is likely going to take over the sporting events. The days of unaugmented athletes being able to perform at the world level might very well be numbered.
I thoroughly enjoyed the book, and can highly recommend it.

Review: Naked Statistics
Naked Statistics is a non-technical introduction to statistics. In terms of explaining the science of statistics to laymen, it does a passable but not stellar job. The basics are straightforward: nearly everyone should know the difference between mean and median (the book doesn't cover "mode"), and Wheelan does a fine job of explaining the difference.
Where the book starts to fall apart is on items such as the Central Limit Theorem and Regression analysis. Both topics are technical enough that you really should just get out a statistics or math textbook and work through examples yourself. The book separates out the technical details in an appendix to each chapter, but I found that treatment unsatisfactory. On the other hand, I'm also the kind of person who'd read a textbook if I really wanted to review this material as preparation.
The book is sprinkled with lots of examples, some of which are fun, but doesn't into enough depth about the anecdotes to really get at the gist of the matter. The author says he was inspired by How to Lie With Statistics, but in my opinion anyone who wants to read this book should read the original instead.
Not recommended. Go read a textbook instead, or the original source of inspiration instead.

Review: Cold Days
Cold Days is the latest available novel in the Dresden Files series. Like the previous couple of books in the series, you are well advised not to read this novel until you've read at least the previous 3 books in the series.
The books at this point suffer from the travails of a D&D campaign that's gone past the sweet spot of the game system. The characters are now extremely powerful and the only way for the DM/author to challenge the players is to keep throwing bigger and bigger challenges and bigger and bigger bad-asses at them.
This is not a bad thing. But as an action series, there's precious little time for reflection on the part of Harry Dresden, and there's even less motivation for him to introspect. We do get a few notices here and there on the part of the temptations he's subject to as the new Winter Knight, but by and large he brushes them off as he spends much of his time going for survival, rather than flexing his powers.
I did enjoy a number of plot twists in the book, and the expanded awareness of his urban fantasy world is a lot of fun for long time readers of the series. If you're already a follower of the series, this is a great book, and worth your time. While it's not necessary to read the entire series, it'd be worth while to at least start from Changes. Recommended.

Review: Ghost Story
Ghost Story is book 13 of the Dresden Files. It is a direct sequel from Changes, and if you haven't read that book you'll not get very much out of this book, because it picks up directly where Changes start. Given that that's the case, I'm going to spoil this book if you insist on reading further on this review.
Dresden was murdered at the end of the last novel, and he wakes up as a ghost, 6 months later, at the start of this one and is charged with investigating his own murder. Unfortunately, there's a complete shortage of clues, and Dresden wanders from situation to situation, trying to resolve more urgent problems than that of his murder, which in fact, he deduced correctly fairly early on in the novel.
In many ways, fantasy is about wish-fulfillment. In some ways, this is Dresden's wish-fulfillment. He gets to see how crucial he was to the community, and how much things went wrong without him for 6 months. The mystery as such isn't much of one, but again, is more like an action movie. It does end up with a setup for the next book, so it's clear at this point that Jim Butcher has given up on standalone novels and is only writing for folks who'll read the entire series.
Only recommended if you're willing to slog through the entire series.

Re-Read: Ender's Game
This is my third time reading Ender's Game, and I've read the previous incarnation of the novel (which began as a short story in 1977) several times over the years. I started reading it because of the upcoming movie based on the novel.
There are several things that date the novel at this point: the first of which is the superpowers of the world back in 1977 were the Russians and the Americans. Obviously, that has changed recently, and but the book doesn't reflect that. Fortunately, this background has little to do with the main focus of the novel.
The novel is compellingly readable, but it lost a bit of impact between the short story of the same name and the conversion into a novel. The short story was focused at it's core: if the horror of war could be distilled away into a child's game, then we could perhaps train children to become amoral warriors. The novel is quite a bit more nuanced, meandering into issues of xenocide, the rightness of abusing a child, no matter how brilliant and no matter how important the purpose. What's worse, the ending of the novel makes it clear that Ender's sacrifice was unnecessary.
Nevertheless, the book, when it does focus on Ender and his travails, is excellent, providing many examples of leadership that real world managers and executives would be well-advised to emulate. Highly recommended.

Review: Changes
Changes is book #12 in the Dresden files. In many ways, the series reminds me of a RPG game. As the characters get more and more powerful, the ante has to ramp up, otherwise, the characters are left with no challenge in their lives.
At least Butcher is willing to make drastic changes in his milieu, resolving a major plotline that's been long-running in the series, which is the war between the White Council and the Vampiric Red Court, while Dresden, the main character, undergoes a major life change as well, picking up yet another family member, a new job, as well as a new life state.
The bad things about the book is that the plot feels like it's been reused. The "little girl in trouble" scenario feels a bit old, because it was just used a couple of books ago. Finally, the end of the book feels very much like a cliffhanger to get you to read the next book in the series. Regardless, there's thrills galore, lots of explosions, and many set pieces. There's not much boring investigation work, but at least Butcher seems to have given up on the "I got bonked on the head, fell unconscious, and woke up someplace different" mode of investigation.
It's good summer reading, a lot like any of the summer blockbusters. I'll pick up the next book in the series soon.

Review: Turn Coat
Turn Coat is book 11 of the Dresden Files. The series finally comes full circle, as Dresden now has to bail out the very person who was his "parole officer" at the start of the series. We finally get a good view of the White Council HQ, as well as the politics involved in the wizards. I still found myself wondering why the wizards seem to be so ineffectual in the world if there were so many high powered individuals wandering the globe. There's a grand climax with big battles. It seems nothing ever gets resolved with a big bang in Butcher's milieu when it could be resolved by multiple nuclear options.
It's still an enjoyable read, though the series is starting to get to the point where Butcher is introducing as many new mysteries in each novel as he's resolving them.

Review: Small Favor
Small Favor is book 10 of the Dresden files. It is so far the best book yet. It's action packed, exciting, and is the equivalent of a summer blockbuster movie.
Harry Dresden is finally behaving like a good hero of the traditional sort: rather than being an investigator who "investigates" by getting thumped on the head, he's now actually driving the action in the novel. For me, anyway, this reads much better than the older novels.
This is the first novel from Jim Butcher where I didn't see gaping plot holes. Everything does come together neatly, and the ending is quite satisfying. The only problem with the series is that jumping into the series at this point is that you'd lose some of the context, but unlike other fantasy novels, Jim Butcher does tie everything in the story off at the end of the novel, so even if you only read one novel it works by itself.
Recommended.

Review: Neptune's Brood
Neptune's Brood is set in the same world as Saturn's Children, but is not a direct sequel in style, tone, or humor. This is a feature, since Saturn's Children, as much as I enjoyed it, was a Heinlein Pastische, and you don't need too many of those.
Science Fiction is often called the literature of ideas because it's frequently lacking in other areas like character, plot, and pacing. As a hard science fiction writer, Stross demonstrates this in this book, which frequently reads more like a treatise in interstellar commerce than a novel. There are long expositions abound in which the reader is lectured to (shades of Asimov) about Fast Money (cash), Medium Money (investments), and Slow Money (interstellar bitcoinage), and how Spanish Prisoner and other fraud schemes would occur in the absence of FTL travel and only lightspeed communications.
Now, all this works only because the characters are all post-human, including the narrator/protagonist (Krina), a historian/accountant who specializes in audits and has a sideline/interest in investigating slow money fraud. As a result, she can "beam" to various locations and travel via starship to places without a beacon. The plot revolves around Krina's visit to her sister Ana. When Ana disappears before she gets there, Krina investigates and gets dropped into a web of intrigue when everyone she talks to, works for, or is arrested by wants a piece of whatever Ana seems to have found before she disappeared.
Like you would expect in a science fiction novel where all the fun happens in the exposition, Krina isn't much of an active entity in the story. She gets dragged and dropped by other forces outside her control pretty much throughout the novel, and never really initiates anything herself. This allows her to exposit on topics that Stross considers important for the reader to know.
The ending, much like with Saturn's Children, comes together in a hurry after the great reveal (which isn't terribly exciting), and leaves the reader with most of the loose ends tied up and a deeper understanding of how Charles Stross feels the entire financial system is. There are lots of snide remarks about investment banking, bankers, accountants, and bank branches (one of them is a pirate outfit), but in the end, the reader isn't likely to gain any more expertise in economics as a result of reading this book than he already had. (On the other hand, Nobel prize winner Paul Krugman liked the book, but of course he would)
Now it sounds like I didn't enjoy this book, but I did. It's just that the audience for this book is likely to be incredibly narrow (geeks who enjoy Economics). To that audience, I'd highly recommend this novel. It explores many ideas that few other science fiction novels do. For anyone else, I'm afraid you're going to have to enjoy lectures or the novel just won't work.
