MissWyvern
The girl's name is Rissa Laurel.
She was a senior in highschool before she dropped out, left her family and began life as a criminal, stealing and killing just to survive.
She's a sexual sadist and murderer with an interest in young women and a creative way of committing her crimes.
Rissa thinks she'll never be caught, but when she stumbles upon the Sorrow Society, a secret and powerful organization of outlaws who serve a Master, the reality hits her.
She needs their protection, their security, but is she willing to serve a Master when the very thing she kills for is dominance?
And what if, against all odds, she finds herself truly falling in love?
