Jon Atack is generally acknowledged as the world's leading authority on the cult of Scientology. He spent nine years in the cult, training as an 'auditor' and becoming 'OT V.’ He’s the author of the definitive biography of Ron Hubbard, “Let’s Sell These People a Piece of Blue Sky.” His new book "Opening Minds," is a must-read that helps explain undue influence and in particular, how to protect yourself from predators.
