A creeping blight is strangling the life from the world, turning lush forests to ash and vibrant villages to grey dust. Fiora, a young woman with fire in her hair and a secret burning in her blood, is the last spark of hope in a dying land. An ancient prophecy reveals she is the key to renewal, but the price is unimaginable. To save her people, she must journey into the heart of the skeletal woods and seek out the fading spirits of the forest—three ancient, magnificent beasts who are more shadow than substance. They are the guardians of a forgotten pact, and their power is failing. The only cure is a ritual older than memory, a primal, life-giving rite that requires the ultimate offering. Fearing for her life but driven by duty, Fiora offers herself at their altar. What begins as a terrifying sacrifice soon transforms into a stunning awakening. In the arms of the monstrous guardians, she discovers that her body holds a power she never knew, and that true surrender can lead to an ecstasy so profound it can remake the world. She came prepared to die for her people, but she may just be reborn as their queen.
