In July 2004, Brent Jeffs filed the first sexual abuse lawsuit against Warren Jeffs, his uncle, the president and prophet of the Fundamentalist Church of Jesus Christ of Latter Day Saints, the polygamous Mormon sect. This suit catalysed a chain of events that eventually led to Warren Jeffs' appearance on the FBI's Most Wanted list and to his arrest and conviction on charges of arranging the rape of an under-age girl. Until now, Brent has never told his whole story. Lost Boy shows what the FLDS is like from the inside, from the unique perspective of a man who was raised in the group and witnessed many of the extraordinary events that led to the largest removal of children into foster care in American history. Through his incredible story, Brent explains how cults like FLDS control their members, how their absolute power corrupts their leaders, how hard it is to escape, and how these challenges affect the many 'lost boys' like Brent who are expelled as teenagers.
