Lila, a quiet library assistant stumbles on her late grandma’s tattered notebook tucked between dusty old books. Inside are coded clues to her grandma’s missing rare local history collection—lost in a 20-year-old fire everyone thought destroyed it. Her estranged cousin suddenly resurfaces, insisting he’s also hunting the set to “claim family heritage.” But Lila spots holes in his story: he references details only her grandma could have shared. Now, the pair races to small-town archives and forgotten storage units. Lila’s goal: donate the collection to the historical society to honor her grandma. If she loses, her cousin will sell the books to a private collector, wiping out the town’s unique stories forever.
