The Graveyard Book by Neil Gaiman
"Recently dead, poor love, she thought. It's always easier to die gently, to wake in due time in the place you were buried, to come to terms with your death and to get acquainted with the other inhabitants."
The Graveyard Book was a recommendation from the Cousin-Who-Shall-Not-Be-Named (pictured below with his mom). It's by the same author as Coraline, and is written for a "tween age" audience. It's a great story, although a bit intense for younger children, and is a good read for anyone over 12. Including me.
