Don't miss the shot

I am a killer, a murder, an assasin. I kill for money. All so I can survive. But I made a bad choice, and it may cost my life. Rick Green is a feared mafia leader. He doesn't like me. I tried to kill him, didn't succeed and now he is hunting me down... or so I thought.

Kasey is a 19 year old girl in the city of Luminaries who lacks a feminine look. She's sharp shooter that hardly ever misses her targets. One day she misses her target and is now on the radar of the infamous Rick Green. Avoiding him at every turn, she runs into him in the most inconvenient places. He try's recruiting her to join him for her skills, or so she believes. Could there be another reason....
