In 1985, Jo Thornely needed to choose a subject for a talk. She decided on cults because she figured ‘almost everyone is at least a little bit fascinated’ by them. She has been obsessed with them ever since, and her popular podcast on the subject — also titled Zealot — has captivated listeners since 2017. In the book Zealot, Thornely details the history and practices of ten cults, with particular emphasis on their leaders.
Zealot makes for frightening reading.
