Mary Roach, also the author of Stiff (the lives of human cadavers) is an investigative journalist with a large funnybone that will keep you turning the pages. Spook gives an overview of society's various theories and experiments related to the afterlife, mediums, ghosts, psychoacoustics,near-death experiences, etc. Facsinating!
Funny in some places, a tad boring in some places, but over all, a good read. I found the chapter on ectoplasm more than just a little interesting and more than a little bit gross.
This book had a lot of potential, but it fell a bit short of meeting my high expectations. Some chapters were really interesting, and I truly loved the author's subtle touches of humor. But other chapters just dragggged. Overall, it's an interesting read, but you might want to prepare yourself to skim through (or even skip) a few of the sections.
If you will be offended by her mocking tone toward God near the beginning of the book, then you might want to avoid this. If you can set that aside, the book is quite fascinating and at some points laugh out loud funny.
Interesting look at the efforts to scientifically investigate the existence of an afterlife. Seemed a bit lightweight, I preferred her previous book Stiff.
