A loyal warrior in a crisis of faith must fight to regain her place and begin her life again while questioning the events of her past. This gripping science-fantasy novel from a Hugo, Nebula, Sturgeon, and Locus Award-winning debut author is a complex, action-packed exploration of the costs of zealous faith, ceaseless conflicts, and unquestioning obedience.

Zenya was a teenager when she ran away from home to join the mechanically-modified warrior sect. She was determined to earn mechanised wings and protect the people and city she loved. Under the strict tutelage of a mercurial, charismatic leader, Zenya became Winged Zemolai. But after twenty-six years of service, Zemolai is disillusioned with her role as an enforcer in an increasingly fascist state. After one tragic act of mercy, she is cast out, and loses everything she worked for. As Zemolai fights for her life, she begins to understand the true nature of her sect, her leader, and the gods themselves.
