Mysterious Skin (by Scott Heim)

I saw this movie when it came out, and it's just astonishing. One of those incredibly powerful, beautiful films that will disturb you and stay with you. The novel is just as good, and in fact, has one of the most amazing last lines ever. I recommend both very highly, although they do tackle subjects such as child abuse and male rape, very graphically, so not for the faint of heart.
