In 2013, the actor Leah Remini left the Church of Scientology after more than 30 years. Her new memoir, Troublemaker, might make her the most famous former Scientologist to publicly criticize the religion. (The Church calls the book "revisionist history.")
The story starts when Remini was nine, growing up in Brooklyn. Her dad had just left, and her mom got a new boyfriend. He was a Scientologist. Her mom joined the church, too.
