Catcher In The Rye and The Adventures of Huckleberry Finn. Both had such awesome heroes, how can you beat a line like "Dat truck 'dere is trash and trash is what people be puttin on the head of dey friens when dey don't deserve it" I paraphrase, but seriously both of those books really really shine. And the end of Catcher when Holden is with his younger sister, probably THE most cathartic moment ever put onto paper. I cry every time I read it.
