For being a short book, I think it took too long to get to the “thriller” aspect. It was mysterious, but nothing was really happening until the halfway point to make it a thriller. I really liked the first half and thought the buildup would be better. The writing is a bit amateur, but it makes for a quick read. I really enjoyed the excerpt from the book inside the book. I would probably read that book and like it better than this one! The ending was a bit unsatisfying. Overall, if you’re looking for something quick, this is a great choice, but it’s not super unique.
