I normally absolutely adore Sterling, his 'Zeitgeist' holds a place of honor on my bookshelf; I found it to be witty, poignant, and full of strangely likable characters. In essence, it's everything this book isn't. 'The Zenith Angle' is really the nadir of Bruce's work. An attempt to spin a tale about the clashing realities of cyber-security and real security in the immediate aftermath of 9/11, but instead, all this book does is clash. The story is a wandering, meandering mess that seems half-finished. Instead of a clear plot with an introduction, exposition, and resolved conclusion, the book reads more like a series of half-finished tirades, and those tirades don't even have a focused direction. Is the book for open-source, or against it? For computer security, or against it? Optimistic about the future, or pessimistic? Who knows? It's never made clear. The characters are almost all utterly unlikable, including the book's 'hero' Dr. Vandeveer. 'Van' as he's called, is a whiny, self-righteous, know-it-all nerd who's a jerk to his wife, not very good at his job, and incapable of having a normal social interaction with anyone. Speaking as a computer geek, very few -real- geeks are like this, especially the ones who get far in fields like computer security. We may lack a bit of social polish, but we're not cold-hearted jerks. None of the other characters are any better; the only character I felt any pangs of like for was a bit-character, a rich business mogul that appears in the prologue, and then gets mentioned a few times throughout the book, apparently having gone crazy, from some combination of old age, BSE, and being tricked by holograms (Yes, really.)
The technology in the books is awful too, it's a glossed-over mix of internet buzzwords, MovieOS fakery, and over-simplified pulp fiction; The sort of schlock I'd expect in a novel by Dan Brown or the other authors that make their coin writing New York Times Bestsellers, but I expect -much- better from Bruce Sterling.
This book is so badly written, so trite, so lacking in depth or emotion that it even made me not care about 9/11, not as it was happening in the book, anyway. Listening to 'Van' snivel and worry about it as it happened on his TV toward the beginning of the book, I mostly found myself wishing one of those planes would hit his house and save me from having to wade through a few hundred more pages of schlock.
If you want to read a poignant, witty, thought-provoking book set in the modern post-9/11 Information Technology world, pick up William Gibson's 'Pattern Recognition' and 'Spook Country'. If you want to read a half-baked rant that appears to have been assembled from rejected bits of other Sterling works, pick this book up. I still hold Mr. Sterling's work in the greatest esteem, and I'll happily read his next effort, I just hope it's far better than this was.
