Wild Eyes

Aylins mother is murdered and her father is given the death penalty when he is found guilty of her murder. She and her sister Lilith live with their aunt and a year and a half after their fathers death a freak run in leads Aylin to discover secrets about her mothers death that she was unaware of. Her mother wasn't just murdered but murdered by a werewolf and its possible the murderer was still her father. Aylin and her sister are half werewolves.
She finds this out from Mr. Lane, a leader of a government branch that takes out magical races who are too dangerous, which is all of them. Luckily as only a half werewolf Aylin and her sister don't pose much of a threat because they can not shift. In fact she could be very helpful to the organization if she chooses to help eliminate these threats to the human race.
In the process maybe she can find out what really happened to her mother and father.
