Still hesitant about giving away too much, but I tihnk this is what I'm gonna put on the back of the book (This takes place in tha late 1800's to early 1900's, by the way):

Orphaned at 7, homeless at 10... viscious murderer by 16

Life for Evolette Brandon has never been easy. From the time she was young, she was surrounded by death and suffering. But instead of letting the pain get to her, Evolette has found a new way to deal with it: Vengance. She does everything from brutally murdering her arch nemesis to blowing up the place where her parents died in an accident. After all, who would suspect a young lady? Evolette is taking her revenge on the world- one sinner at a time.
