Mercy Thompson is a mechanic in Washington. She is also a shapeshifter who was raised by werewolves. She bought her shop from her mentor Zee when the Fae were forced to come out to the public. Most of them now live on reservations. Humans think that this is keeping them under control. The Fae have other ideas.
There have been a series of murders on the reservation. Zee brings in Mercy in hopes that she will be able to smell someone who has been at all the crime scenes. When she pinpoints the common person, Zee and another Fae go to confront him. They find that someone else has already killed him and Zee is found in the house when the police arrive. He is arrested and the powers that be in the Fae world decide that he is a convenient scapegoat for the human police. They don’t want them digging any deeper into the worlds that the Fae have set up on the reservation.
Mercy doesn’t want to let Zee be set up. She decides to dig deeper into the murders which bring her in contact with a human anti-Fae group.
This is my favorite book in the series so far. In the first two there is a love triangle, which I am not a fan of. This is resolved in this book.
The ending is unexpected and actually made me a bit teary. I’m moving over to the Spoilers page to talk more about it.
