Six years ago, little Katherine Harlow killed her own parents. Showing no signs of remorse or regret, she was said to be a girl without a soul. Now, dressed in black except for an expressionless white mask, Kat kills for the dead - a willing vessel for the souls of the wrongfully killed that call out for vengeance.
