Mindfuck Books

Anyone have any recommendations for books that will fuck with your head for a person that doesn't read all that often?
I read American Psycho, Lolita, A Clockwork Orange, and A Scanner Darkly (Most particularly enjoyed Lolita). Are there any books in that general sense?

Much appreciated.

That list is total BS. Real literature like Dune, Fight Club, and Snowcrash mixed in with lots of pretentious shit. Wow, just wow. At least he puts the best as A People's History of the United States by Howard Zinn. That almost saves that God-forsaken list.
