A week ago, Hart came back and brought a friend. But something has changed, and Gracen is seeing Hart when she's awake too. And the other "friends" in her dreams? They have been found dead. The police want to talk to her. Her dreams are becoming more and more intense. Hell wants her. Heaven has to stop her. In the end, Gracen has to fight the evil eating away inside her or will she be forced to embrace it and destroy the world?
