The second novel in the #1 New York Times bestselling series. A demon-riding vampire has gone on a killing spree unlike any the Tri- Cities has ever seen-and the undead and werewolves sent to stop him haven't returned. A coyote is no match for a demon, but shapeshifting mechanic Mercy Thompson is immune to many vampiric powers-and those are her friends who are missing, including the two werewolves circling around her heart. Game on.
