What are some good teen books?

I don't believe that people give Neal Shusterman enough credit. His book "Full Tilt" is easily in my top five best books ever, and hey, I read adult fiction. Not to say it's similar to adult fiction as it is still a teen novel, but yeah. Full Tilt was amazing-- better than a lot of other books of his I've read. It's about a boy who gets trapped in a phantom carnival and has to try and find his brother while he has to ride seven rides in order to get out . . . and he also only has a certain time to do it.
