The Fires of December (Hoid's Travails, #3)

In the next Cosmere standalone novel, Hoid has an epic tale to share: In a forgotten land sustained by colorful rivers of demon blood, a young woman named December learns a devastating plague is on its way. But who will believe her? Against impossible odds, she sets sail up the River Violet to warn the king's court, determination—and wisdom beyond her years—burning in her eyes. Along the way she’ll navigate incredulous royal officials, twisted court intrigue, and a roguish count with only her wits and her new friends: a talkative priestess and a fledgling fashion designer.
