The story itself is fascinating and scary. For me though, the writing style kept me detached. While I understand that the majority of the story had to be recreated from third-party sources, those portions of the book felt very clinical. I enjoyed the last quarter of the book better, when the author was actually drawing on her own memories. It had more of the feeling of an investigative piece rather than the memoir style I was expecting, but it was a quick and interesting read.
