Family reunions suck.

What's a woman to do when her dad's the antichrist, her grandma's the devil, the end of the world is at her doorstep, and she's out to avenge the murders of her husband and kids?

Kill everything in her way.

Quarter-demon Peri Takata exists with but one goal in mind: annihilate everyone responsible for the death of her family. Then—her need for vengeance quelled—she plans to take her own life.

Her mission brings her to vampire Zara Lain, the only known survivor of the event that destroyed Peri's family five years ago. Hunting down a secret society of those who don't want to be found has its challenges, however, especially when forces are working to keep the antichrist's daughter very much alive. The apocalypse is closing in and Peri may be playing a role in it whether she wants to or not.

And when a heart long-thought dead begins to beat again with love for another, she's not so sure about anything anymore.
