it depends entirely on what you are interested in. i like challenging books, books with great prose, epic battles, good and evil, the dark underbelly and the brightest lights, moral struggle and the birth of new ideas.
tell me what you are interested in and I'll see what i can think of.
i'd read lolita, though. it is such an incredible book. he almost convinces you that Humbert's act of preying upon an innocent child is an act of love and caring. almost. but the reality is that he's a monster. "an artist and a monster."
