After taking down a corrupt margrave, breaking a deadly curse, and finding romance with the vexingly scrupulous junior prefect Emeric Conrad, Vanja had one great mystery left: her long-lost birth family . . . and whether they would welcome a thief. But in her search for an honest trade, she hit trouble and invented a god, the Scarlet Maiden, to scam her way out. Now that lie is growing out of control - especially when Emeric arrives to investigate and the Scarlet Maiden manifests to claim him as a virgin sacrifice.

For his final test to become a prefect, Emeric must determine if Vanja is guilty of serious fraud or if the Scarlet Maiden - and her claim to him - is genuine. Meanwhile, Vanja is chasing an alternative sacrifice that could be their way out. The hunt leads her not only into the lairs of monsters and the paths of gods, but also the ties of her past. And with what should be the simplest way to save Emeric hanging over their heads, he and Vanja must face a more dangerous question: Is there a future for a thief and a prefect, and at what price?
