I just finished reading a scary book called Prophet's Prey by Sam Bower about the fundamentalist break-off from the Mormon Church, called the FLDS.  Brainwashing and the use of the church as a breeding farm for innocent young girls as wives for the church's elder men while the boys were eliminated from the church and cast off with nothing to support them was a way of life.  The prophet and his ilk living in luxury while imposing a despotic rule and confiscating people's money was described. It is a tale of horror and anybody wanting to learn something of bizarre religious organizations will find a lot to consider.  I highly recommend it.
