Brielle of Thornbrook has dedicated her life to the abbey. She spends her days forging iron and her evenings studying the Text, all in preparation of becoming an acolyte. Twenty-one years on this earth and she has never touched a man. And she never will. But when she finds an injured stranger in the forest, Brielle can’t resist the urge to help him. The encounter leads her to the realm of Under, where the air breathes rot, and the fair folk dance and whisper. Where she discovers that the man she helped is actually a Zephyrus, the West Wind, Bringer of Spring. There are few Brielle can trust in Under, least of all Zephyrus. He is charming, dangerously so, and never has a man so thoroughly ensnared her. As she embarks on a journey through the eerie banks and caves of Under, Brielle finds herself in a perilous situation. For here is where faith and heart collide – and where she risks not only her future… but her life.
