By day, Mercy is a car mechanic in the sprawling Tri-Cities of Eastern Washington. By night, she explores her preternatural side. As a shapeshifter with some unique talents, Mercy has often found herself having to maintain a tenuous harmony between the human and the not so human. This time she may get more than she bargained for.
Marsilia, the local Vampire Queen, has learned that Mercy crossed her by slaying a member of her clan—and she's out for blood. But since Mercy is protected from direct reprisal by the werewolf pack (and her close relationship with its sexy Alpha), it won't be Mercy's blood Marsilia is after.
It'll be her friends'.

Mechanic Mercy Thompson can shift her shape - but not her loyalty. When her former boss and mentor is arrested for murder and left to rot behind bars by his own kind, it's up to Mercy to clear his name, whether he wants her to or not.

Mechanic Mercy Thompson has friends in low places-and in dark ones. And now she owes one of them a favor. Since she can shapeshift at will, she agrees to act as some extra muscle when her vampire friend Stefan goes to deliver a message to another of his kind.
But this new vampire is hardly ordinary-and neither is the demon inside of him.

Mercedes Thompson, aka Mercy, is a talented Volkswagen mechanic living in the Tri-Cities area of Washington. She also happens to be a walker, a magical being with the power to shift into a coyote at will. Mercy's next-door neighbor is a werewolf. Her former boss is a gremlin. And she's fixing a bus for a vampire. This is the world of Mercy Thompson, one that looks a lot like ours but is populated by those things that go bump in the night. And Mercy's connection to those things is about to get her into some serious hot water...
