"I never thought life could get more complicated after death. I guess I was terribly mistaken."
Michelle Dorin seems to be your average seventeen-year-old rich girl with dysfunctional parents--except for the fact that she's been dead before. Months after her revival, she discovers that a demon is sharing her body and plans on snuffing her out completely. Her only confidant is Julian, an edgy classmate that has the same condition, but has mastered it. He offers to teach Michelle how to handle living with the demon if she agrees to train and help hunt them. But it's not easy to steer clear of temptation when you're not sure if the voice inside your head is your own or something else.
Can the unlikely duo save our world from demons that disguise themselves as ordinary humans, or will their strange and growing attraction toward each other drag them both to hell?
On the eve of Michelle's first official demon hunt, her mentor and love, Julian, briefly loses himself and sets off a chain of events that make Michelle question if he ever had control in the first place.
With the help of her new ally, Diana, she is able to cast out Zariel once and for all. But there's hardly cause for celebration when Balthazar unleashes a full-scale attack on Julian's mind.
Balthazar and Maria transform Michelle's life into a constant state of horror while moving on with their plans for humanity's end. Michelle trains her new powerhouse protege to help her face the upcoming evil, but Balthazar's terror extends further than Michelle can imagine.
Michelle desperately searches for a way to save what's left of Julian's soul, but the only salvation may very well be his death.
