What first caught my attention with this book was the concept of a character trying to solve what turns out to be a decades-long mystery. I enjoyed the way the story was told through different time periods and different characters and getting to read along to see how it was all connected. 

It was sufficiently creepy with a kick-you-in-the-gut ending that always makes for a satisfying horror read.

It was fast-moving and reminiscent of an X-Files-type Monster of the Week story, which I loved. In a strange way, it also reminded me a little bit of The Invisible Life of Addie LaRue - if Addie LaRue was a much darker and much more evil person. 

I would recommend it to anyone looking for a quick, dark, and mysterious read with a creative premise. However, if you enjoy happy endings that are tied up neatly in a bow, this might not be the best book for you!
