Coraline - Neil Gaiman

Simply said, watch the movie. I have never seen a movie and a book so perfectly similar.

Coraline tells the story of a girl who finds a small door in her house that leads to another world. The other world is very similar to hers except not quite. People have buttons for eyes and her other mother is trying to take her soul. Its a good read but I still think you can get the exact same experience from watching the movie which is quite good.
