For her, it’s her late grandma’s legacy. For him, the mother of all black magic spoils, granting one demon the power of a God. Immortality.

When jaded Ruby does shots with a charming stranger at a bar, her life goes to Hell… literally. Demon Lord and darkness incarnate, Drayvex’s viperous allure becomes the least of her problems when she loses a sentient dark relic to his light fingers. But when Drayvex himself loses it to a dangerous foe, Ruby enlists him –the tyrant with a soft spot for humanity– into helping her save her pokey village from becoming a ground zero of mass demonic carnage.

Both equally obsessed with reclaiming the relic, the only thing Ruby and Drayvex agree on is that it’s in the wrong hands. Co-existing in a volatile, hot-and-cold accord between predator and prey, to save the planet they both love for different reasons they must become a formidable double-team in the face of an apocalyptic takeover. Now, the fate of both human and demon alike rests with a killer that walks between worlds, and a woman with a curse in her bloodline.
