Something is missing in Maple Hollow... and Ellie Watson is determined to find it.

When a mysterious crash shatters the quiet morning in Maple Hollow, ten-year-old Ellie Watson is the first to spot the broken window at the local music academy. What begins as a strange incident quickly turns into a full-blown mystery when the town's prized violin; an antique with a legendary past; disappears without a trace.

With the help of her best friend Caleb, Ellie follows a trail of puzzling clues: a red feather on the lawn, a hidden passageway behind a bookcase, and whispers of a vanished violinist from decades ago. But the deeper they dig, the more tangled the mystery becomes; and someone in town seems desperate to keep the truth buried.
