Undercover even to myself

Aria Bright is a normal teenage girl who has to move to a different school at 16. Strange boys are always near her and she doesn't know why. So she does what she normally does at school try to avoid everyone and everything possible. There are some very different things about her though. Aria is an assassin. She is known as Shadow because of her clothing and the fact no one lives to see her without her consent. How will she hide her secret when there are so many people paying attention to her. What happens when she meets some odd wolves almost like they are protecting her. SO what is she to do when there are so many confusing things happening what is an alpha, what about a luna, or perhaps a beta and why do people keep saying lu, but stoping themselves from finishing it? Last question, why do people keep bowing to her when she commands them to do something. "Ok lu, Aria where would you like me to move it?" Blake asks. "Over there," I say pointing to the right. "Alright now, what do you want me to move lu, Aria?" Blake asks. "Take a break and answer me this, why does everyone keep calling me lu, I have been here for 2 months you should know my name by now?" I say slightly annoyed. "Sorry lu, Aria it's just natural for us," Blake says.
