Brandon Sanderson's Cosmereuniverse includes an ever-expanding library of unique new adventures for fans of both Mistborn and The Stormlight Archive. That will continue with The Fires of December, Sanderson's next standalone Cosmere novel, which receives its wider physical release on December 8, 2026, following an earlier premium release for crowdfunding backers. The new story offers another opportunity to explore the massive interconnected universe Sanderson has spent decades building.
