Question:

What are some good young adult books to read over the summer?

I have already read all of Laurie Halse Anderson's books, the Sisterhood of the Traveling Pants series, all [or most of] Carolyn Mackler's books, some books by Virginia Euwer Wolff [Make Lemonade series], and a lot others. Some suggestions would be helpful but please don't list the ones I said I read. Thank you!

P.S. I know a lot of people ask questions like this but I felt like finding out for myself. Thanks!
