Scientology and the Sociopath Next Door

Going Clear is probably the best single synopsis of the subject, from Hubbard to what goes on in Scientology. I also highly, highly recommend bare-faced Messiah, the unauthorized biography of El Run Hubbard by Russell Miller. If you want some fun supplements to reading Mike's book, there are things you can look up on YouTube like you had very dramatic experience on BBC show Panorama with John Sweeney.
