I enjoyed the creepiness of Coraline by Neil Gaiman, so I was keen to read The Graveyard Book by him. As it happens, I haven't read it. But I've begun listening to Neil Gaiman reading from it, as he's read the whole thing and put it on the Internet:
There's a great review of the book by Patrick Ness. The story is a kind of supernatural, spooky mystery. From the start, you are not told who the murderous "man Jack" is. Will Bod who at the age of two narrowly escaped the murderer find out? How will he grow up in a graveyard, with only ghosts to look after him? Mystery upon mystery.
