Warren Jeffs is the current and infamous leader of Fundamentalist Church of Jesus Christ of Latter-Day Saints (FLDS). He is also the half-brother of Wallace Jeffs, the author of Destroying Their God. FLDS is an offshoot of Mormonism, though the Mormon Church does not recognize it. Polygamist Mormons formed FLDS after the Mormon Church renounced polygamy in 1890.
Warren Jeffs is currently serving a life sentence for child sexual assault. He married and raped young girls, forced his wives to have sex with each other, and built a creepy ranch to keep his followers from having any contact with the outside world. Destroying Their God is a fascinating glimpse into the insular FLDS community and how Warren Jeffs used fear, exploitation, and isolation to consolidate power and commit loathsome crimes in the name of God.
