Yumi, a demon saintess raised in isolation, survives the destruction of her village only to discover she's too valuable to kill. Decades within temple walls left her ignorant to the world -- and the worlds -- beyond them. Her powers were repressed. Her life, controlled. Now she's a prisoner in a foreign court where even kindness feels like a weapon at her throat. The crown prince is dying. Only she can save him. Survival means learning to trust the people who destroyed everything she knew, for better or worse -- and Yumi's not sure that's something she can do.

A tale of power, deception, and unexpected connections in a world where demons, spirits and humans collide. A story of a long, long time.
