Talking to dead people

The thought of talking to the dead really intrigues me, mostly because it's not really something I believe in. My initial thought was that the book was based on an interesting concept. I enjoy reading the most when the story can be considered "outside of the box." The idea of talking to the dead has been done before but it is such a versatile subject that the author could really go in any direction with it. I'm looking forward to reading more of the book (I've already begun) and finding out where the author takes it.
