Nothing on Scientology, though.
From the Guardian:
Sam Jordison is the author of Crap Towns, a guide to the UK's worst places to live. His latest book is The Joy Of Sects - An A-Z of Cults, Cranks and Religious Eccentrics.
"Literature would be considerably poorer without cults and religious extremists. They've inspired some fine novels and riveting eye-witness accounts as well as producing rainforests' worth of mad, bad and thoroughly dangerous books themselves. Reading all this stuff made researching my book a fascinating and enjoyable experience. Here are 10 of the best I encountered on the way."
I feel like I'm a bad person because I've never read any Crowley. It's a situation that must be rectified. I'll ask my dad if he has any when I see him next.
