Spook: Science Tackles the Afterlife

Spook: Science Tackles the Afterlife - Mary Roach This book was a fascinating read, first is finding out that attempting to find the weight of a soul was actually considered scientific. Then the various "studies" to prove or debunk the spirit world or figure out when a soul entered the fetus. (after 14 days because before then you could have identical twins and each couldn't have 1/2 a soul)

I was astounded to find that reputable universities have a paranormal studies divisions. They are named somewhat differently but when you're trying to prove or disprove spirits they're paranormal. The writing style is informative and tongue in cheek.
