Irish ballad

Hyland Barnes, is not your normal Irish girl: A hunter, a Marine, an assassin
Every single day, she looks into a mirror, and yells monster. She can make a kill from more than half a mile away, and she is unbeatable in hand to hand fighting. She wants one wish: to kill herself. That is until she meets Sam Winchester...
Sam Winchester: A hunter, a brother, and loves Hyland Barnes
Will he be able to fix a broken soldier with the help of a few friends?
"Sam enough! You can't fix something that is in pieces!"
"Watch me Hyland. I made a promise that I would fix you. And I don't break promises. Let me in, I'll fix you!"
