When Danica Marsden isn't tailing cheaters or tracking missing persons, she's grappling with a lifetime of chaos. Years of therapy haven't helped; even the raucous barfights and one-night stands are losing their savor. Danica has learned to live with the fire inside her, along with the dreams that haunt her nights, of a celestial tree and a winged, divine woman who seems to know her. Until the night her reality shatters. Pursuing a target, Danica encounters a man whose face warps into something inhuman, yet familiar. Then her own reflection begins to flicker, revealing a stranger beneath her skin. Desperate for answers, she's intercepted by two intoxicating half-demons with a taste for blood: Shahara, stunning and lethal, and her half-brother Rhavin, a charming predator with a gentle touch. They claim Danica isn't who she thinks she is, and that her blood ties her to an infernal empire ruled by Lilith, goddess of serpents and shadows. Drawn to both dae'val, Danica follows them to a lush, depraved realm of feral witches, hellbeasts, and captive gods. But Danica's true heritage is only the beginning. If she can't unravel the secret at her core and stop the forces gathering in Lilith's court, her world will be the next to fall. Her only chance at salvation lies with Rhavin and Shahara, who have been vying for her love for centuries. And they won't settle for less now.
