If a book mentions cults, I'm almost certain to pick it up. However, that's usually fiction. This one delves into real life cults. I was shocked at some of the grand scale of these cults, and their acts, that I had never even heard of. This comes across as a very well researched book, and the author ads a little bit of humour to the telling. Plenty of details, but without going too graphic into the treatment of others. Fascinating stuff.
