Wright knows how to weave an informative narrative in an engaging manner: his style is not lurid, but neither is it dry. I read this on my Ipad, and embedded within the text were some video interviews with the various ex-members whose stories are featured in the book. One of my only criticisms of the book would be that the long list of names was sometimes difficult to keep straight--the video clips helped to clarify the identities of the players.
As to the content of the book, it's hard to describe concisely. The book traces Scientology more or less chronologically, starting with Hubbard's childhood and progressing through his life, then, as his movement is handed off to others once he becomes ill and subsequently dies, following his inheritors. Wright dutifully supplies endnotes to either verify his own reporting or provide pro forma denials from the Church (and sometimes both). The exercise quickly becomes farcical, as Wright's heavily researched events clash against flat and unsubstantiated denials from the Church (or, in the latter part of the book, Tom Cruise's agent). Wright will detail an event, backed up by several corroborating witnesses and court documents, while the Church will simply issue a statement that says more or less, "That never happened."
There can be little doubt that Hubbard was mentally unstable at best, outright insane at worst. This, I knew, if dimly. What I did not know was the level of cruel depravity he could and did sink to--depravity which is even now still present in the Church. I won't go into detail--you need to read the book for that--but suffice to say if you are, as I was, thinking that Scientology is a wacky but largely harmless pseudoreligion you are quite wrong.
It's as evil a cult as ever was. Read this book.
Be seeing you!
