Looking at the church of Scientology, one can’t help but ask what constitutes a religion in the first place. Going Clear takes an in-depth look at the faith, from its creation by science fiction writer L. Ron Hubbard to its current celebrity followers like Tom Cruise. Along the way, the book questions how much power the church really has, and if its clergy are actually being held captive under billion-year contracts. Whether you’re already familiar with Scientology or not, this eye-opening book is definitely worth checking out.
