Inside Scientology: The Story of America's Most Secretive Religion

Inside Scientology: The Story of America's Most Secretive Religion is a 2011 book by journalist Janet Reitman that examines the Church of Scientology. Reitman, a contributing editor for Rolling Stone, began studying the church in 2005. She published an article in Rolling Stone about Scientology the next year and continued her research for five years.

The book covers the history of Scientology and discusses prominent Scientologists such as L. Ron Hubbard and Tom Cruise. It details the church's business model under the leadership of David Miscavige. It also describes Scientology controversies, such as the Death of Lisa McPherson. The book devotes some attention to Scientology's broader teachings.

After its release the book was criticized by the Church of Scientology. A spokesperson for the church alleged that the book was poorly researched and contained numerous inaccuracies. Reitman disputed their claims, maintaining that she did extensive research.

According to a review published on The Village Voice, Reitman's book is a "stunning overview of everything" and calls the author a "thorough, brave journalist."
