If you want a shorter taster, the novella The Freeze-Frame Revolution is also brilliant (and it has a handful of short stories that expand the universe, something Watts has done with several of his novels). Very, very dark stuff.

Watts is somewhat divisive, it should be said. Personally, I love his knife-edge prose and punk aesthetic, and I find his rather unvarnished perspective of humankind's place in universe refreshing.
