Not terribly exciting. The characters were flat. The setting was strange in a fairly unbelievable and uncompelling way. I disliked the ending because it relies on my least favorite mystery thriller trope: when a first-person narrator knows all or part of the big mystery but never shares this in the narration.

Grady knew that he attempted to kill Abby but never shares this in his narration despite constantly wondering about the circumstances of Abby's disappearance.

I think is lazy writing and a way to come up with a thriller without writing a real twist.
