I find Charles Stross' works to either be very good, enjoyable and thoughtful (Eschaton #1, the Laundry series, etc), or very much not my thing (Accelerando.) This work falls, fortunately, into the former category. Stross spins up a believable, well-fleshed out post-human world ruled by a very believable form of future capitalism run amok, and takes the reader on a journey that contains some genuinely enjoyable twists and turns. All in all, a very enjoyable read.
