I've not read a fiction book the whole way through for ages.
I'm currently reading books from the Science Master's series:

and my favourites so far are:
The Origin of Humankind by RICHARD LEAKEY - about the evolution of 'homo' from monkey men to us, and the environmental pressures that caused said evolution
River Out of Eden by RICHARD DAWKINS - the evolution story up to monkey man
The Last Three Minutes by PAUL DAVIES - theories on how the Earth / the Universe is gonna end
They're all a piece of piss to read and they're really interesting. Atm I'm more interested in this shit than your average fiction book.
If you want fiction that gives you a headfuck, which I'm guessing you do from your list of books you like, and like I do too, then The Dice Man by Luke Rhineheart tells the story of a psychiatrist who decides to forget about his own desires and his ego and the Self and to roll a dice for every decision he makes in life, eventually viewing Chance as God and starting a cult and turning into a proper nutjob. And the sequel 'the Search for the Dice Man' is also very good too, about the guy's son trying to track him down and becoming a bit of a dice man himself, although people tend to prefer the original.
