When Sera Littlejohn meets a violet-eyed stranger, he reveals a supernatural battle veiled in the shadows, and Sera is tempted to the edge of madness by a dangerous desire. Ferris Archer takes Sera under his wing, now that she is a talyan—possessed by a repentant demon with hellish powers. Archer's league of warriors have never fought beside a female before, and never in all his centuries has Archer found a woman who captivates him like Sera.

With the balance shifting between good and evil, passion and possession, Sera and Archer must defy the darkness and dare to embrace a love that will mark them forever.
