New York Times Bestseller -- 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. Mercy's loyalty is under pressure from other directions, too. Werewolves are not known for there patience, and if Mercy can't decide between the two she cares for, Sam and Adam may make the choice for her.
