His body for his life. Cass has been fleeing his brutal sister since high school, but when she unleashes an Eldritch Horror that hungers only for his blood, he quickly runs out of time. He has one chance to save his life, one chance to build a future that involves something beyond terror and bloodshed. The deal is simple, he gives his body to a demon in exchange for protection. But Cass never expected Colm to take his heart too, and their arrangement’s lifespan is only as long as the rest of his sister’s life. And with both ticking down, Cass fears that despite everything he’s given to secure his future, none of it is worth anything if he must face it alone.
