The book has all the positive attributes of the 1st 2: breakneck pacing, tons of action and explosions, great computer geek authenticity, lots of memorable characters. The message of social justice, civil rights, and equality for all is even stronger, yay! I also liked how much of the story involved China and India - realistic for 25 years from now.
The conclusion of this installment of the series is such that I think that he is done with the series. It definitely is uplifting in its attitude, and I strongly recommend it. Interesting that in an appendix on the tech, he doubts that this tech will be available by 2040, which is when the novels are set. I think I concur.
1 odd thought I had reading this final novel: I kept wondering, why didn't he leave the uploaded intelligence out of this series, and put that in a separate series? The 2 memes are both very strong, I think there could have been plenty done with just the wetware meme, perhaps even a more thorough exploration of the meme, and, somehow, the uploaded intelligence meme muddied the waters? Ha ha, I'll have to ask him to refactor it into 2 series! I bet with modern tech it wouldn't take that long.
