When a storm uncovers a brass lantern in the attic above her grandmother's repair shop, twelve-year-old Nia Calder discovers a map that appears only when someone tells the truth.
With Tomas-a new friend who collects maps and questions-Nia follows the glowing path through a library visited by the tide, a hill of singing chimes, and an orchard that keeps the moon in its branches. Somewhere along the way, Brackenridge's missing North Star story is waiting to be remembered.
But the lantern cannot undo loss. It can only show the way. To bring the story home, Nia must learn that listening is a kind of bravery-and that some things are repaired not by changing the past, but by carrying its light forward.
