So what's on everyone's summer reading list? I still need to look through my stack of books and see what I have waiting. I'm also looking for good titles to share with my sons-- they're just finishing 4th and 5th grades, but read well above grade level so it's always a challenge to find the right books. Challenging enough, but not too "mature".

I'm thinking of giving them the Earthsea books since they loved Le Guin's Catwing books.

What are you reading?
