Beneath the peaceful streets of Bramblebrook lies a world of secrets. And the Curio Club—Lila, Mia, Toby, and Jake—are the guardians of them all.
Life has been quiet since they discovered the Heart of Bramblebrook, but when the village prepares for its annual Summer Festival, a strange new mystery arises. An old stone statue, long covered in moss, is suddenly restored to gleaming white, and a mysterious message painted on its base warns of shadows, speaking stones, and a secret about to be taken.
As the full moon approaches, the friends realize they aren't the only ones who know about the tunnels beneath the village. A mysterious woman in black has arrived, claiming to be descended from a legendary figure from the village's past, and she will stop at nothing to claim the Heart as her own.
With time running out, the Curio Club must follow a trail of clues, raven symbols, and hidden passages to protect what they love. But will they be ready when the statue finally speaks?
