This is a mystery fantasy. We follow this detective who has been invited to stay at this mansion of a billionaire. It's in an isolated island.
What I like about this story is the atmosphere. In this world there are angels flying around and the depiction of the angels are creepy! They have no face, they have long arms and legs and wings like a bat. Whether it's intentional or not, if you kill two people, the angels will come and get you and drag you down to hell. It's dystopian.
It was fun trying to figure out who dunnit and how.
I enjoyed reading about a detective who is a live person rather than a "tool" used by the author. He even had some friends and their stories are very well blended in with the whole setting. Even though the trick was not so surprising, the story itself is worth 4 stars.
