Gelya is a Vessel, a girl who channels the word of the One True God through song. Cloistered with the other Vessels of her faith, she believes—as all Ovinists do—that a saint imprisoned Elath the Great Demon centuries ago, saving humanity from earthly temptation.

When Gelya stumbles into a deadly cover-up by the Ovinists’ military, she reluctantly teams up with Tavik, an enemy soldier, to survive. Tavik believes that Elath is actually a mother goddess who must be set free, but while he succeeds in opening Her prison, he inadvertently turns Gelya into Elath’s unwilling human vessel.

Now the church that raised Gelya considers her a threat. In a race against the clock, she and Tavik must find a way to exorcise Elath’s presence from her body. But will this release stop the countdown to the end of the world, or will it be the cause of the earth’s destruction?

And as Tavik and Gelya grow closer, another question lingers between them: What will become of Gelya?

• Enemies to Lovers: She’s a holy Vessel; he’s an enemy soldier who worships the very being she now carries. To survive, Gelya and Tavik must trust each other, but their growing closeness might be the most dangerous thing of all.
• A Chosen One with a Terrible Destiny: Gelya has spent her life channeling her god through song. Now, betrayed by her church, she has become the unwilling vessel for the Great Demon her faith taught her to fear.
• Gods, Goddesses, and Betrayal: The Ovinist church is built on a lie, and the ‘demon’ Elath may actually be a mother goddess. Uncovering the secret history of her world will force Gelya to question everything she holds sacred.
• A Race Against the Apocalypse: As Gelya and Tavik search for a way to exorcise Elath, the end of the world ticks closer. But is freeing the goddess the key to salvation, or the cause of total destruction?
