In an empire on the brink of war . . . Ahn is no one, with no past and no family. Altan is a lost heir, his future stolen away as a child. When they meet, Altan sees in Ahn a path to reclaiming the throne. Ahn sees a way to finally unlock her past and understand her arcane magical abilities. But with kingdoms crumbling around them and war on the horizon, they may have to pay a far deadlier price than either could have imagined.
