This book has a LOT going on. Just when I thought I had a handle on things, the author would switch it up and leave me wondering again. I absolutely loved going on this ride with Mary, so much so that I was sad when it ended. I feel like I can't talk about it much without giving the surprises away, so I won't. I will say it should be on the TBR pile of anyway to likes well-written, genuinely suspenseful horror.
