What is the main conflict in Inside Scientology: The Story of America's Most Secretive Religion by Janet Reitman?

Inside Scientology is an in depth, albeit critical, look at the religious movement known as Scientology. Journalist Janet Reitman follows the religion throughout history to discover the inner workings of a controversial faith from its humble beginnings to its rise in power, slow breach with reality, and its near ending. As a nonfiction book, Inside Scientology does not include a traditional conflict, but rather, addresses the challenges and controversies of Scientology itself.
