Someone there mentioned never having heard of the sequel, so.. FYI, there's a sequel! It's called Freedom™[0]. It's very much one story split into two volumes, not "our heroes go on a new adventure".
And as I said in that thread, for another great fictional portrayal of AI, see Person of Interest[1]; it starts as a crime procedural with an AI-flavored twist, and ended up being considered by many critics the best sci-fi show on broadcast TV.

His recent work is great too. Also I've met Dan a few times at Defcon and he's a really great and interesting guy.
The first of his books I read is "Kill Decision" which has more than held up in it's predictions of drone warfare and AI advancements. Based on the accuracy of his predictions from this book, and Daemon too, I'm bullish on space mining!
