What are some good books for a 15 year old girl?

I have read the Twilight series. In fact, I'm re-reading Eclipse right now. I have The Host. Ummmm I like stories about animals....It's really hard to find REALLY good books. I'm somewhat reading The Canterwood Crest series even though it's for younger readers I still love it. I don't like books like the Clique series. I'm going to see if I can go to Borders or Barnes & Noble today....but I can always walk to the library. What are some books that you have read that you really like?
