Five hundred years have passed since the territory war that permanently separated two neighboring kingdoms, Verna and Hanin, destroying all hope and birthing even darker shadows from the depths of its trenches. Yona of the Song family has dedicated her entire life to protecting her twin brother, Suoh, who was cursed with magic in a world that actively seeks to destroy it.

But when Suoh and the imperial princess disappear, leaving a trail of bodies behind, Yona finds herself trekking across The Waste with an unlikely ally in search of them.

Her journey takes her to places she's never seen before and threatens to flip her entire world—as well as her sense of self—on its head.
