I was intrigued by this book because I am so interested in human psychology and this sounded like such a cool thriller. I ended up not liking it as much as I'd hoped, but it was still very creepy and I read it super fast! It's written as a series of blog posts chronicling one doctor's experience with a particularly dangerous and difficult patient in the psych ward. Multiple other patients in the hospital and other doctors would go mad or commit suicide after interacting with him. The blog post-format meant that the perspective was very one sided and based on files and memories rather than being in the action. The ending was very unbelievable and took a turn from a complex psychological thriller to a fantastical horror story. I would recommend to people who like horror and stories written to seem like they're based on real life - it was a quick and engaging read. Trigger warnings: sexual assault, domestic abuse, mental health issues.
