In a forgotten land sustained by rivers of demon blood, December has spent her life trying to fit the roles others gave her. Then she learns that a cataclysmic plague is coming, one that will curdle the rivers and ravage the kingdom, and no one is likely to believe a poor woman from a small riverbank town.

Joined by a chatty priestess, a fledgling fashion designer and a roguish count who may hold the key to her quest (and perhaps her heart), December sets out up the River Violet to warn the king's court. A standalone Cosmere novel of Hoid's travails, demons and destiny from Brandon Sanderson, perfect for new readers and longtime fans alike.
