First of all, Lolita. Nabokov is a god at prose. This is by far one of the greater novels I've read in terms of sentence composure. This man can write. It's a sad, disgusting tale about how a guy named Humbert Humbert tries to rationalize to the reader that what he is doing with a 12 year old girl is morally right. Don't fall into his entrapment.
Ulysses by James Joyce. Just do it, you know you've been 'meaning' to.
