Like every member of the Dirk & Steele Agency, Blue Perrineau is far from "normal"—and he believes in the organization's creed: Protect the innocent in secrecy. Now an obligation to the family that rejected him is leading Blue into the light and shadow of Sin City . . . and to a remarkable woman, beautiful, desirable, and untamed. Iris is a headliner in Vegas, dazzling crowds with her feral sensuality and her uncanny affinity for dangerous beasts. But there is a darkness in her world that she never knew existed, and a champion has appeared to protect her—a man charged with electricity, who guards a secret as strange and powerful as her own. And every secret is a liability when darkest evil exists that follows no rule under heaven. Yet with passion and love sustaining them, together Blue and Iris might yet live to see the dawn.
