Abgrall details the mechanisms by which cults attract, ensnare and brainwash new members, and discusses types of people most vulnerable to cult recruitment.
This book covers many different angles on the subject. The writer is French, but the organization and methods of cults seems to be universal. It's interesting that his research may outlaw (or has already) many practices of Scientology in France, but in America they are more protected by freedoms granted by our laws.
I didn't get a chance to finish this one before I had to take it back to the library. I'll have to check it out again sometime.
