Prominent ex-Scientologist Leah Remini is penning a tell-all about her experiences inside the Church, Random House’s Ballantine Books revealed Thursday.

The “King of Queens” actress defected from Scientology back in 2013, and has been an outspoken opponent of the organization since then. “Troublemaker: Surviving Hollywood and Scientology” will focus on Remini’s indoctrination into the church at the age of 10, her rise to fame, and her eventual break with the Church. Per Ballantine:

"In Troublemaker, Remini, best known as the star of the popular long-running sitcom King of Queens, will detail for the first time her life growing-up in the Church of Scientology and her rise to fame in Hollywood. Indoctrinated into the church as a child while living with her mother and sister in New York, Remini eventually moved to Los Angeles, where her dreams of becoming an actress and advancing Scientology’s causes grew increasingly intertwined. But when she began to raise questions about some of the church’s actions, she found herself a target, which led to her—and her family’s—break from the church. Bold, brash, and bravely confessional, Troublemaker chronicles Leah Remini’s remarkable journey toward emotional and spiritual freedom, both for herself and for her family.”

Remini’s memoir comes on the heels of “Going Clear,” Lawrence Wright’s tell-all expose and Alex Gibney’s follow-up documentary, which shone light on allegations of the Church’s abuses and featured testimony from numerous ex-Scientologists. Now it seems that Remini is joining the chorus.

“Thank you to the brave who did something about it,” Remini tweeted in March, praising the team behind Gibney’s “Going Clear” doc. “And to those who didn't have a voice, you do now.”
