Hallie. A Tit for a Tat. Deamhan Chronicles, #3.5

A teenager turned into a supernatural predator must survive a world she never asked to join while powerful enemies target her for a war she doesn't understand. Hallie Mortenson never wanted this life. She never asked to become a Deamhan. She never asked to lose the sun, inherit a supernatural hunger, or be thrown into a world where survival often comes at the expense of morality. Sired in violation of ancient laws and forced to adapt to a life she barely understands, Hallie struggles to find her place among creatures who have spent centuries navigating darkness.
While powerful factions wage war around her, she is still trying to understand what it means to become one of them. But when her sire returns to the city, Hallie's fragile sense of stability begins to unravel. He carries dangerous secrets and a hidden agenda involving an ancient Deamhan determined to exact revenge on his entire sire line-including Hallie. As enemies close in and old grudges resurface, Hallie must decide what kind of person she wants to become before someone else decides for her.
Set in the world of the Deamhan Chronicles, A Tit for a Tat is a dark urban fantasy novella about identity, survival, and finding your place in a world of monsters.
