Adopted into the mafia

My name is Athena, but some know me as The Huntress, I'm a well-known assassin, I can make a grown man cower in fear, and can lure them in just one look, hence the name.
I've been in foster care since I was a baby, every time I'm adopted, I'm thrown into an abusive home, so I became a cold-hearted bitch at ten years old, and started street fighting and street racing, never in the six years I was there has someone defeated me.
One day a group of Elite assassins saw my skills and hired and trained me to be the assassin I am today. I'm the best at what I do.
Now I'm almost eighteen which means almost out of foster care, but of course something had to get in the way.
Let's say that the Italian mafia has no idea of what is about to hit them.
