I like James Joyce, "Ulysses" and "A Portrait of the Artist as a Young Man". "1984" is my all-time fav. I've read it about 7 times. I loved "On the Road", Kerouac; "The Maltese Falcon" Dashiell Hammett; "Cat's Cradle" and anything Vonnugut; "Point Counter-Point" Huxley; "Farewell to Arms" Hemingway; "One Flew over the Cuckoo's Nest" Ken Kesey; "Catcher in the Rye" or anything JD Salinger. The last book I read was "The Way of all Flesh" by Samuel Butler and to be honest, I couldn't get through it, it was too midwest-frontier-y to me. All the others I listed aren't like that, they really held my interest.
Supposedly Catcher In the Rye is not good unless you read it before you're eighteen. Otherwise people find it dumb and childish. If you do read it as a teenager though, most everyone can relate to the protagonist in some way.
Is Portrait really good? For my Lit class this year we were supposed to read four books during the summer and then we spend all year disecting them. Portrait is the last one we do and I haven't read it yet, though supposedly from what I heard in class..it's horrible.
