D | I don't mind reading books with gore and dark topics so it's not even the contents of the book itself that dropped this down to this grade. If anything, it's the fact that this book reads like a rough draft. It's simply an outline. There's absolutely no substance what so ever in this book. The only reason it's not getting a lower star rating (or none at all) is because the author did a good job depicting how cults work and what they do to their members. Aside from that, this book was a straight-up disappointment. I should have expected it when I saw how short the book was, but I was at least expecting something more than a rough draft getting published somehow.
