On the eve of Ashpeak's legendary Lantern Festival, Evy and her companions arrive with one goal: to uncover the truth hidden beneath the eternal flame - a lantern that has burned for centuries without ever going out. What they find instead changes everything. When Evy discovers her long-lost parents alive, she believes the search is finally over. But shadows twist beneath the village streets, and the Watcher no longer stalks them alone. As the eternal lantern is moved to light the festival, rifts surge, secrets unravel, and the thimble reveals itself at last. To claim it, they must descend beneath the Hall of Flame into a place where fire does not warm but consumes. And even then, one question remains: what are they willing to burn away to hold onto what they love?
