In a city where only warriors rule, one girl's forbidden power could change everything—if it doesn't destroy her first. Ellie has failed at everything. Transferred from Quarter to Quarter, she can't manifest the right magic or escape her own inadequacy. When she's assigned to an elite mission with Mace Hardfield—the golden boy she's loved since childhood—it's her last chance. But Ellie isn't broken. She's a Shield, a wielder of ancient magic that Central Command has spent centuries erasing. As she uncovers forbidden truths, Ellie learns her city is built on lies—now she must lead a revolution and prove the girl everyone dismissed is their strongest weapon—all while fighting for the one person she can't live without. For fans of Red Queen, An Ember in the Ashes, and Fourth Wing.
