In Sin City, a little girl suffers from a strange and terrible malady. If she dies, the Light will die along with her. Warrior, avenger, Joanna Archer has survived countless otherworldly terrors-and has found her rightful place among the agents battling the all-pervasive evil of Shadow ...even as she struggles against the darkness within herself. A war is raging for Las Vegas-a city without a heart-one that catapults Joanna into a new world hidden from mortal sight. In this lethally seductive alternate dimension the lines blur between good and evil, love and hate, and here lies the last hope for the Light. But Joanna's price of admission is a piece of her own soul-and the odds of her escaping are slim ...to none.
