Rapture of the Nerds is about what you'd expect from a collaboration between Charlie Stross and Cory Doctorow: brimming with big ideas, clever in the technical details, a little on the unfocused side when it comes to actual storytelling.

I enjoyed it. Didn't care much for any of the characters, but I don't think you're supposed to. Some of the plot developments were predictable, many weren't; in at least one case a Chekov's Gun feels like it doesn't quite fire, but for the most part the authors do a great job of following up on the plot threads they start. The climax is clever if, again, unfocused and over too soon.

Well, I guess this makes for a somewhat unfocused review lacking in followthrough, too, which is appropriate enough -- I thought I had more to say but I guess I don't, and anyway I'm tired. The book's well worth a read, and since it's creative commons you can read it for free and then decide if it's worth more than that to you.
