I'm not one of you

Ella is a pretty damn good hunter if there ever one but there was one thing she hunted her own kind. Her adoptive mother taught her everything she knows and being a werewolf did help her a lot on missions, even though no one other than the hunters she's close to can know of what she truly is .
But now she's been sent to take out the alpha of one of the most major packs in the world what will happen?

Sorry I'm not very good at descriptions and not very good at grammer/spellings either :S but please read :)
