For two hundred years - since her nightmare days in a Sultan's harem - Kyana has straddled two worlds. Mercifully "turned" by a stranger, she's half-Vampyre, half-Lychen - the last of her kind - with no love for the mortal race that once imprisoned her. But the Order of the Ancients fears humanity's annihilation is at hand, and entrusts Kyana with a mission: find the mythical key that will seal the realm of Hades for eternity...whatever the cost.
Kyana is furious to learn her mission 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 resists. For it could only mean the undoing of them both now that a traitor walks among the gods.
