His Assassin

I was his exception. He favored me.
I was his secret. He was my home.
I was his midnight. He was my Alpha.
I was his assassin. He was my father.

This is the life of Angel. A mixed breed of Vampire and Werewolf. She is rare, and she is a slave. An assassin to a person whom she despises, her own father. But one day he asks of her to do the worst thing possible. Date the bad boy. She finds out that he is one of her mates and loves him unconditionally. But what happens when another person claiming to be her mate shows up, and he's a vampire.
