As a young child, Zerryn grew up on tales of the Lord of Death, Erlik Khan, and his penchant for stealing wild girls. In her small village, she keeps to herself and tends to the temple gardens, spending her days with her best friend Çelik. But when Çelik begins to act strangely and removes himself to live on a crumbling estate atop Mount Ida, the rumors of him becoming possessed by a demon begin to swiftly arise. Each month that passes the demon within him grows stronger, his demands of the villagers growing oddly disjointed and nonsensical.

Her chances of saving him become all but impossible once Zerryn learns that it is no lesser demon that has a hold of him but Erlik Khan-a demon of untold power who lords over the dead. It isn't long before word spreads that he is in search of a bride, and creatures of untold power come before him to rule by his side. Zerryn knows that she cannot take down Erlik without power and she cannot gain power without becoming his bride.

But becoming Erlik's wife is nothing as simple as an offer for his hand. To become the queen of the Underworld, she must complete three impossible tasks or risk losing everything she holds dear.
