Any good books recommended for a pre-teen kid?

Huh. I'm getting a lot more bored lately, and the books that I have right now are starting to get old. *sigh* Anyways, I'm planning a trip to the library later on, and I'm thinking of taking out a few books. Can you give me some good books that are recommended for a Young Adult Audience? (I already read Hunger Games, Read the entire Artemis Fowl series, have Catching Fire on reserve...)
