This original paper back (1988) has now been updated, revised, and expanded in the 25th anniversary edition, released in March 2015. This book has helped thousands of ex-members and their families, therapists, clergy, as well as law enforcement understand the use of mind control techniques in cults. A former cult member, now a counselor helping those affected by destructive cults, Hassan exposes the troubling facts about cults' recruitment, their use of psychological manipulation, and their often subtle influence on government, the legal system, and society as a whole.
