The world will soon find out.

When soldiers arrive from the Holy Order of Woodsmen to claim a pagan girl for the king’s blood sacrifice, Évike is betrayed by her fellow villagers and surrendered.

But when monsters attack the Woodsmen and their captive en route, slaughtering everyone but Évike and the cold, one-eyed captain, they have no choice but to rely on each other. Except he’s no ordinary Woodsman—he’s the disgraced prince, Gáspár Bárány, whose father needs pagan magic to consolidate his power. Gáspár fears that his cruelly zealous brother plans to seize the throne and instigate a violent reign that would damn the pagans and the Yehuli alike. As the son of a reviled foreign queen, Gáspár understands what it’s like to be an outcast, and he and Évike make a tenuous pact to stop his brother.

As their mission takes them from the bitter northern tundra to the smog-choked capital, their mutual loathing slowly turns to affection, bound by a shared history of alienation and oppression. However, trust can easily turn to betrayal, and as Évike reconnects with her estranged father and discovers her own hidden magic, she and Gáspár need to decide whose side they’re on, and what they’re willing to give up for a nation that never cared for them at all.

Imagine a city where electricity is money, power the only game worth playing, and violence the most fervently worshipped religion.
