DS11 likes science fiction and reads at graduate school level (ok, that's just a guess lol, but he can read basically any level book you give him). I'm trying to find new book ideas for him for Christmas but I've never been a fan of science fiction - any suggestions for books that are for adult-level readers but ok for an 11 year old to read? I think he's read most of the sci-fi type books you find on the teen shelf at the book store.

Thanks,
