Eva: a time-lost warrior who believes that God wants her to rid our world of the foul things that lurk in the shadows. Cassie Hack: a 21st century anti-heroine who has devoted her life to the elimination of 'slashers' who kill without mercy or reason. These lethal ladies and their monstrous majordomos Michael and Vlad may seem like two sides of the same coin, but they're as different as night and day. When a mysterious figure brings them together, the whole world's going to be reminded that Hell hath no fury like two women on a mission in a city full of monsters!
