Mercy Thompson's life has undergone a seismic change. Becoming the mate of Adam Hauptman—the charismatic Alpha of the local werewolf pack—has made her a stepmother to his daughter Jesse, a relationship that brings moments of blissful normalcy to Mercy's life. But on the edges of humanity, a minor mishap on an ordinary day can turn into so much more. After an accident in bumper-to-bumper traffic, Mercy and Jesse can't reach Adam—or anyone else in the pack for that matter. They've all been abducted. Through their mating bond, all Mercy knows is that Adam is angry and in pain. Outclassed and on her own, Mercy may be forced to seek assistance from the most unlikely of allies: the vampire seethe.
