In this dark, sweeping fantasy perfect for fans of Girls of Paper and Fire and Wicked Saints, Princesses Lu and Min find themselves on opposite sides of a war to rule their Empire.

Sisters Lu and Min have always known their places as the princesses of the Empire of the First Flame: assertive Lu will be named her father's heir and become the dynasty's first female ruler, while timid Min will lead a quiet life in Lu's shadow. Until their father names a new heir--their male cousin, Set.

Determined to reclaim her birthright, Lu goes in search of allies, leaving Min to face the volatile court alone. Lu soon crosses paths with Nokhai, the lone, unlikely survivor of the Ashina, a clan of nomadic wolf shapeshifters. Nok never learned to shift--or to trust the empire that killed his family--but working with the princess might be the only way to unlock his true power.

As Lu and Nok form a tenuous alliance, Min's own hidden power awakens, a forbidden, deadly magic that could secure Set's reign . . . or allow her to claim the throne herself. But there can only be one emperor, and the sisters' greatest enemy could very well turn out to be each other.

This sweeping fantasy set against a world of ancient magic and political intrigue weaves an unforgettable story of ambition, betrayal, and sacrifice.
