A good book to one person is a piece of crap to another.
But if you don't mind reading in the YA area, the book, The Hunger Games, is wonderful. That whole series is quite good. It's a futuristic tale of a forced game played by teens to the death. Only one can survive and if your picked to play, you'll probably die and if you don't die, you'll have to kill friends. It's quite excellent. It doesn't feel like YA at all.
