Fleeing internet notoriety, Grace is scooped up by a corporate think-tank where her unnatural gifts can be studied. But disaster continues to stalk her; she’s attacked by the faux-demons of a witchy rival, befriended by a half kachina bad boy, and must fend off the advances of a love-struck mothman. If that weren’t bad enough, ISIS, a secret society, is raising Hell—and the dead—to get her to the last Halloween party ever. Surrounded by enemies, she must save the world without drawing the attention of the Lord of Shadows, her father.
