If you'd like to try a Children's Book ...

Read The Graveyard Book by Neil Gaiman. Presented as a set of interlinked stories, it tells of Nobody (Bod) a lad whose life was saved as a tot when he wandered into said graveyard. Someone Very Bad had just done away with his family and wants to do the same to him. I know! It totally sounds familiar! The tone is both lighter and more mysterious than those books about the kid with the glasses. Bod is raised by ghosts and learns their ways - disappearing, walking through walls - but if he leaves the graveyard the Very Bad Someone will immediately pounce. The Graveyard Book is even better than Coraline, and that's saying something kids.
