Everyone expected Violet Sorrengail to die during her first year at Basgiath War College—no one expected her to rise as one of its most formidable riders. But the real war is only beginning. As secrets unravel and the enemy grows bolder, Violet must question everything: her command, her relationships, and even the truth about magic itself. With danger closing in and trust harder to come by, survival isn’t enough—Violet must choose what she's willing to sacrifice to change the future.
