How can Cal live when the monster remains in the mirror?

Cal is struggling. After his past unravelled into a torment that claimed nearly his whole family, how could he not be? The only good left in his life is Layla, even if she comes with a pain-in-the-haunches incubus. Dealing with Ink is one more problem he's ignoring, until the werewolf issues he's refused to face come for him.

A second pack is hunting him and they're threatening his mother. Cal has no choice but to travel back to Santa Fe and confront them or lose the last family he has left. While a road trip with Layla sounds nice, Ink has to come along, and the demon keeps driving a growing wedge between Cal and his tenuous grasp on humanity.

Cal, Ink and Layla come face to face with an enemy Cal once believed to be nothing but a myth, his claws and fangs useless against their firepower. What do they want with the witch, werewolf, and demon? And, most of all, how can they be stopped?
