Alana is a half Kubiteron demon, half witch who witnesses a Matusa demon's murder of his summoners. He sees her in her astral form watching him and she's next on his list of victims. Hunter is half human, half Matusa demon, fighting to keep the evil ones out of the human world. When he's poisoned, he sees the vision of a girl watching him, only she's not really all demon and not really all there. She offers to save his life, if he offers to protect her from one of his kind. But no lesser demon dictates terms to a Matusa. Jared is a full Elantus demon, raised by humans, who's searching for his real parents. When Hunter saves his life, he vows his loyalty to him and designs a tracker device to locate demons entering the human world. When Alana beats on Hunter's chest to get his heart beating again after he dies, twice, he knows the half demon is hot for him. Often at odds, the three teens work together to stop the plans of a group of Matusa to take over the human race before it’s too late.
