This felt like a classic isolation thriller. It reminded me of the meta slasher film, Scream, because of the characters knowing so much about the mystery genre such as the rules, thinking the killer must be one of them, and never splitting up but still being outsmarted by the killer. The twist did shock me and there was a lot of elements of this book where I thought the author was smart in how he executed the story. I never suspected the killer nor the ending of this book and that’s all I can ask for with a thriller.
