ok, i might have posted here before, but nevertheless, here is my list of absolute favourites:
1) Gulag Archipelago - Alexander Solzhenitsin (just mind-blowing)
2) THE CASTLE and THE TRIAL by Kafka
3) Atomic Particles (atomised) by Michel Houellebecq
4) Lolita by Vladimir Nabokov (a book that is brilliant in so many ways, also funny as hell)
5) Hunger by Knut Hamson
6) Sophie's Choice - William Styron - A really good read, great story
7) It's me, Eddie - Edward Limonov, very honest, raw, dirty, if you liked Tropic of Cancer, well, its a much better choice
There are just so so many other books, Parfume (yes, briliant book), 1985 and, oh yeah, The Holographic Universe by Michael Talbot - mind-blowing, totally anxiety-inducing, controversial and unproved, if you're into that.
