In Need of a Fantastic Book?

I just went on summer break from college and don't know what to do with myself. Know any good books? I adore fantasy, and am a fan of Robin McKinley, Phillip Pullman, J.R.R. Tolkien, C.S. Lewis, J.K. Rowling, and Christopher Paolini. However, I've read all of their books and am looking for something new. Any suggestions of a similar author or genre? My husband recommended the Dragonlance books, but I thought they were a little lame. Any help would be appreciated. Thanks a'bunches!!
