Author Brandon Sanderson expands his Cosmere universe shared by The Stormlight Archive and Mistborn with a new standalone novel for everyone who loved The Princess Bride. The only life Tress has known on her island home in an emerald-green ocean has been a simple one, with the simple pleasures of collecting cups brought by sailors from faraway lands and listening to stories told by her friend Charlie. But when his father takes him on a voyage to find a bride and disaster strikes, Tress must stow away on a ship and seek the Sorceress of the deadly Midnight Sea. Amid the spore oceans where pirates abound, can Tress leave her simple life behind and make her own place sailing a sea where a single drop of water can mean instant death?

#1 New York Times bestselling author Brandon Sanderson brings us a gripping story set in the Cosmere universe told by Hoid, where two people from incredibly different worlds must compromise and work together to save their worlds from ruin. Yumi comes from a land of gardens, meditation, and spirits, while Painter lives in a world of darkness, technology, and nightmares. When their lives suddenly become intertwined in strange ways, can they put aside their differences and work together to uncover the mysteries of their situation and save each other’s communities from certain disaster?

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.
