I'm currently reading Ghosts Among Us: Uncovering the Truth about the Other Side by James Van Praagh. A co-worker lent me this book and I'm enjoying this nice easy read. James Van Praagh is a medium who also developed the television show The Ghost Whisperer, which is based on the life of a friend of his, who is also a medium. In the book, James talks about his experience with ghosts and explains his beliefs regarding the afterlife. There are lots of anecdotes and well as protection techniques and exercises.
