She is the beginning and the end.

She is peace and chaos.

She is terror knocking at the gates.

Estranged from her powerful family, Lilith Leviathan finds refuge in Nineveh, a district in the city of Eden devoted to sin. There, she uses her magic to steal for a living, attracting the attention of the five governing families as well as the church, which expects women to remain pious and silent. When Lilith comes into possession of a beautiful blade, she thinks all her worries are over . . . until her usual buyer dies while inspecting it.

Frantic, Lilith turns to the only man who can help her: Zahariev, head of the Zareth family and ruler of Nineveh. His currency is information, and his power is extortion, though he's always had a soft spot for Lilith. But when the dagger appears, he isn't sure he can protect her from what's to come.

Together, they embark on a mission to discover the true power running their world. As their lives intertwine, Lilith realizes Zahariev is more than just a friend, but their devotion to each other is a threat—to the truth, to the church, and to those who want to tear it all down.
