The gates of hell have opened, and one woman will stand in the crossfire as the Dark Breed—vampyre, demons, shape shifters—and mankind fight their last battle for survival. Kyana is half Vampyre, half Lychen... and the last of her kind. Determined, dangerous, and damned, she has no love for the mortals who have imprisoned and misused her. But when the Order of Ancients entrusts her with a mission—to find the key that will send the Dark Breed back into Hell for eternity—Kyana has no choice but to accept. She is furious to learn her assignment comes with an escort... Ryker, a demigod and fierce warrior who long ago found a way under her skin and stayed there. In a shaky alliance, they discover an ancient cult with dangerous motive and a god who seeks to destroy all others. And as Kyana begins to feel the heat that threatens to bind her to Ryker, she knows she has to resist. For it could only mean the undoing of them both...
