This memoir is an extremely thorough account of the historically significant and mysterious Sea Org (the original Sea Org, not the modern iteration operating on dry land) as well as the time period leading up to, during, and after Scientology was banned in parts of Australia (where Grady is from). In contrast to memoirs by other ex-Scientologists, Grady was quick to recount her positive experiences in Scientology, of which she had many. She was also quick to defend Scientology and its members when they were repressed or falsely accused of wrong-doing by governments and the media. That lends much more weight to her descriptions of her negative experiences, than if she were to only focus on the harmful aspects of Scientology. Also, like many other ex-Scientologists, she did not sensor full names, dates, or locations for the sake other people's privacy. I imagine that this memoir (and its sequel) would stand up in court as a first-hand testimony. And it would be invaluable to historians or anyone else doing a deep-dive into early Scientology history.
Unfortunately, I found the entire memoir boring. Sorry, I just did. It read more like a ships log -- a series of unrelated anecdotes and facts with no real plot line, with a very neutral tone of voice. Ironically, all of these factors are exactly what would make it invaluable in certain settings. She include details which would seem mundane to the casual reader but could be pivotal pieces of the puzzle for an investigator. The fact that her tone of voice is neutral and unflowery, makes her words much more trustworthy and unambiguous. But, unfortunately, it also makes the memoir boring for the casual reader.
So, if you are a casual reader just looking for entertainment, skip this one. But if entertainment is irrelevant to you and you are looking for a fair, unbiased, and extremely thorough account of the early Sea Org and early Australian Scientology history, this one is for you.
