The Alpha's Assasin

Emerson Mae was never treated quite right. Always pushed to her limits but never considered enough for her pack. She was left on the doorstep of an Alpha and Luna as a baby. Not knowing where she came from the Alpha automatically gave her the position of Omega. Everyone laughed at her, picked on her, and thought little to nothing of her. Until she turned 16, then everyone feared her. She discovered that she was not only a werewolf but a witch as well, making her more powerful than the rest of her pack. Therefore she was banned, the Alpha fearing his bloodline would no longer hold the title of Alpha. She did her best to survive on her own and ended up becoming an assassin. But what happens when she takes a job requiring her to take down the most powerful Alpha there is?
