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.

Alana Fainot is a demon gate guardian, stuck in her last boring year of school. But not for long. Hunter and the rest of the gang show up when her astral form can't return to her physical form, and she's at the police station trying to talk her way out of having seen the murderer of a summoner.Hunter always knew Alana was trouble, but his kind of trouble, and he's not leaving Alana alone again.Celeste Sweetwater, a new kind of demon, joins Hunter and Alana and the rest of the demon guardians in a fight to find a new kind of portal device that can summon several demons at once. But not only that, another Matusa has been unleashed on the unsuspecting human world and the demon guardians must stop him before he wreaks much more havoc.But this time, the police are involved, paranormal investigators pounce on the area, and the whole mess seems to be spiraling out of the demon guardians' control.

Hunter is half a Matusa demon, determined to help his human-raised demon friends return to the demon world to find their families. And to help Alana learn a way to keep portals from pulling her to them, and getting herself into all kinds of trouble. Not that she can’t handle some of the trouble on her own. She’s a half demon too, and half witch. Jared is looking for his parents. Celeste is looking for hers. Samson is there to protect Alana, though Hunter keeps reminding him Alana is his to protect. It was a simple mission, but nothing for the demon guardians is ever simple. Between dealing with a demon who is organizing demon hunters—who go after Hunter and his friends, a major train wreck, and all sorts of havoc, it’s no wonder the demon gate guardians end up calling in reinforcements this time. As long as Hunter can get Alana to agree to be his mate, he can save the world. Alana will never give up her hot demon, but she believes he should work a little harder to prove he is the one for her. And he’s not going to give up trying to convince her either. But they still have one little staying alive long enough to do it.
