Graveyard Book by Neil Gaiman (NEWBERY WINNER)

Neil Gaiman is one of my favorite authors. If you liked Goosebumps books as a kid, this is another author who will appeal to you and take you to the next level. Also look for Coraline (also a movie), Stardust (also a movie, but the book is better) and Neverwhere. He has great creepy stuff, lots of references to other stories and is just a great writer.
