Obligatory Blightsight recommendation for intelligence != consciousness.

That book is badass on so many levels. I'd just started it again yesterday.

that book messes with my head every time I read it, it's like I go through life in a detached way for several weeks. I need to read it again!

I read it once, was immensely impressed, can't bear to read it again. In fact I find most of what I have read from Peter Watts to be brilliant but disconcerting and uncomfortable.
