Enter Mary Roach, and her research into this subject as well as The Spiritualist movement, Reincarnation, and multitude of other misunderstood subjects.
Mary travels with experts along this crazy revealing ride. She even enrolls in medium school, to try to understand what it means to be a medium, delves into what creates life, even tackles the Ghostbuster associated Ectoplasm.
Spook: Science Tackles The Afterlife is a well written informative read that kept my attention throughout and was very difficult to put down.
For anyone interested in the science's take on the afterlife this is a must read. For those in the paranormal field this would be like doing homework in school, meaning this is absolutely essential to understanding both sides of the coin.
