Hirka has been sent to the world of the blind, a powerful and immortal people whom she has been taught to fear since infancy—and who now see her as their only chance to reignite a thousand-year-old war. The blind will use Hirka's ability to travel between worlds to return to Ym, the land where Hirka grew up and where the blind were betrayed all those years ago. And this time, they will prevail. Hirka is torn between her loyalties to the people who birthed her and the people who raised her, between the savior she is expected to be and the individual she wants to be. Every choice she makes pulls her further away from Rime, the love of her life, who is doing everything he can to stop Ym from falling to pieces all around him. A million things stand between Hirka and Rime. But only together can they stop the end of the worlds.
