Chosen

Two worlds lived in parallel to each other, the Magik realm, and the Humag realm. Every month, On the full moon, the demons and aliens from Magik come and feasted on the blood of the mortals. The only thing that stands in their way is the Executioners, whose job is to protect humanity.
This story follows Rose Yvoskinoskys, the youngest in her bloodline of exceptionally well trained Executioners. But when she watches her parents being murdered on her first demon hunt, and being claimed by the very demon who killed her parents, she knows that she is doomed to either die or suffer for eternity at the hands of the very demon who killed her parents.
