The Graveyard Book by Neil Gaiman
I love this book! Gaiman is a beautiful writer--both his person and his words. Nobody Owens' adventures are the perfect way to end the day and every chapter is its own little story. You and the littler ones will enjoy reading about ghouls, ghosts, the hounds of god, vampires, and the man Jack.
