Shapeshifter Mercy Thompson's life is calming down, at least enough that she can focus on mundane matters like Black Friday sales. But on her return, Mercy is unable to contact her mate, Alpha Adam Hauptman, or the other members of their pack. All she knows is that Adam is angry and in pain. With the werewolves fighting a political battle to gain acceptance from the public, Mercy fears Adam's disappearance may be related - and that he and the pack are in serious danger. Outclassed and on her own, Mercy may be forced to seek assistance from the most unlikely of allies: the vampire seethe.
