Sometimes, you need a demon to fight demons.

Lincoln Marshall is a small-town deputy with a very big problem. Six members of his church have been found dead, killed by a rogue werewolf. He'll have to make a deal with the Devil to save victims that have gone missing — maybe literally. Elise Kavanagh, preternatural investigator and exorcist, is the expert when it comes to violent deaths at the jaws of evil. She's also among the most powerful demons that Hell has spawned.

Elise jumps at Lincoln's case, and it's not just because of his down-home charm. Someone's laid a trap for her in Northgate, and she wants to find out who. She'll have to team up with Rylie Gresham, Alpha of the last surviving werewolf pack, to figure out who's trying to blame the murders on werewolves. Only together can they stop the killings — and uncover the secrets buried in Northgate.
