From Amazon's review:
Whatever your opinion of Scientology, the truth is more extreme.
An in-depth overview and exploration of the Scientology religion, and its effects on some of the people who've been sucked into its world.
I'm not a fan of religion and I wanted to see how deep goes the craziness. Thing is, Scientology is crazier and more dangerous than you could have imagined. I recommend this book highly. It is a somewhat weighty tome; be prepared to slog through some chapters that detail the inner workings of a group of people who truly believe that all our problems come from an alien visitation million of years ago.
