It keeps getting weirder.

The only thing that might be more fascinating than Leah Remini's riveting Oct. 30 "20/20" interview about her three decades as a Scientologist is what's in her upcoming book "Troublemaker: Surviving Hollywood and Scientology."

Various media outlets have been sharing tidbits from the memoir ahead of its Nov. 3 release and it's juicy, to say the least. Many of the headline-making tidbits concern the Church of Scientology's most famous member, Tom Cruise, 53, whose power within the faith worried the "King of Queens" actress, 45.

"I had seen behind the curtain. There, in the role of the great and powerful Oz, was not [Scientology founder L. Ron Hubbard], as I had come to believe, but instead, it seemed to be Tom Cruise," Leah writes in the book, according to Radar Online. "Was my church falling apart? Was Tom in charge?"

Among the revelations Leah shares:

- According to Radar Online, Leah writes that she was invited to be a part of Tom's entourage, which also included actors Ethan Suplee, Jenna Elfman and her husband Bodhi Elfman, and Marosol Nichols. Leah alleges that high-ranking Scientologists Kirstie Alley and John Travolta were not welcomed into Tom's inner circle of friends. "I had heard Tom didn't like them," Leah explains.

- Leah got the impression that Tom was a "big kid" with "goofy ideas of fun." For example? He decided a group of friends -- which that night included Jada Pinkett Smith -- should play hide-and-seek in his 7,000-square-foot home, Radar Online reports.

- Leah also writes about witnessing Tom going off on subordinates, according to the Radar Online report. He once allegedly berated a female assistant for, he believed, failing to properly prepare cookie dough and screamed at her, "Get in the f---ing present time, is what you need to do," before it emerged that the cookie dough was there in front of him. "It was horrible to watch someone I admired come undone," Leah wrote, "and even worse to witness the fear in the assistant's eyes." She alleges that Tom also had a meltdown when another assistant handed him a chipped coffee mug and implied that the helper was a "f---ing DB" -- a derogatory term in the faith that stands for "Degraded Being."

- Leah reportedly claims that after Tom and Katie Holmes' 2006 wedding, his daughter Bella Cruise -- whose mother is Tom's second ex-wife Nicole Kidman -- trashed the Oscar winner: When Leah asked Bella during a shuttle ride to the airport how Nicole was doing and if she and brother Connor Cruise got to see her often, Bella allegedly replied, "Not if I have a choice. Our mom is a f---ing SP." SP Is a Scientology term for "Suppressive Person," or someone who has defied or failed to support the church and its teachings.

- Leah's book confirms reports that "Homeland" actress Nazanin Boniadi, one of Leah's friends, was prepped by church leaders to become Tom's secret girlfriend, which allegedly involved being told to dump her then-boyfriend and wear a new church-approved designer wardrobe. After three months of secretly dating, Leah says Nazanin was dumped by Tom and then -- after she spoke about her experience with a friend -- tattled on by a fellow Scientologist and punished with four months of menial labor. Leah writes that the actress and her family left the faith while Tom got engaged to Katie Holmes. "Naz had been manipulated and lied to, all in an effort to keep Tom Cruise happy," Remini writes, according to Radar. "For him to have dismissed her without saying goodbye or speaking directly to her seemed beyond cruel."

- According to a report in the Daily Mail, Leah writes about how before Tom and Katie's 2006 wedding in Italy, she witnessed their daughter Suri Cruise, who was then 7 months old, crying on a bathroom floor while Tom's sister, assistant and another woman stared at the infant as if she was "L. Ron Hubbard incarnate." Leah, a mother of one, explains that she eventually convinced the women to pick up crying Suri and give her a warm bottle.

Scientology officials have slammed Leah -- who, along with her entire family, left the religion in 2013 -- and her book, telling "20/20" that "She needs to move on with her life instead of pathetically exploiting her former religion, her former friends and other celebrities for money and attention to appear relevant again." The church also accused Leah of "revisionist history."

Leah has said she knew there would be backlash, but thought it was important to share her story. "I decided I didn't want to raise my daughter in the church because from what I've experience and what I saw, the church becomes your everything," she said on her TLC reality show "Leah Remini: It's All Relative" earlier this year. "It becomes your mother, your father, your everything. You are dependent on the church."

"Troublemaker" is available on Nov. 3 via Random House imprint Ballantine Books.
