it took me a month to get through this book. amazing, considering my usual speed with the written word, but quite true. this behemoth refused to be devoured in my usual hours-at-a-time fashion, nope. more like very high quality cheesecake, in that it's so rich you can only take a few bites before you need to assimilate.

part of the story is about a WWII GI, who happens to be so gung-ho and talented at both completing difficult missions successfully and staying alive at their completion that he gets the dubious honor of being assigned to a squad so top-secret he has no idea what he's doing there. part of the story is about a brilliant but oblivious mathematician (clearly an asperger's syndrome kind of guy) who becomes a codebreaker during the same war. and part of the story is about the computer-programmer grandson of the latter and his infatuation with the tough-as-nails granddaughter of the former. part of it is about codes (both for war messages and for computer programs) and part of it is about war (both physical and digital). all of which makes it sound very dry when it's anything but.

Stephenson's typical doses of randomly-applied hilarity are out in full force here. he does an incredible job of painting the world through the individual voices of his characters...and quite often, those guys are thinking very odd things about very odd situations. the hefty book could have been trimmed by, say, 30% if it left out these random observations, sometimes comical, other times simply beautiful examples of what letters can do in the hands of a gifted wordsmith, but then we'd miss out on things like:

"a red dragonfly hovers above the backwater of the stream, its wings moving so fast that the eye sees not wings in movement but a probability distribution of where the wings might be, like electron orbitals: a quantum-mechanical effect that maybe explains why the insect can apparently teleport from one place to another, disappearing from one point and reappearing a couple of meters away, without seeming to pass through the space in between. there sure is a lot of bright stuff in the jungle. randy figures that, in the natural world, anything that is colored so brightly must be some kind of serious evolutionary badass."

no, i'm not recommending it to everybody. it's long and meandering and insanely technical in many places. but yes, i am gushing about it. it's lovely.
