Knock Three Times!

On their ninth birthday, twins Jack and Molly receive a mysterious gift from their Aunt Phoebe: a strange object called the Grey Pumpkin. The elderly aunt, who disapproves of adventures almost as much as she disapproves of bangles, has no idea what curious magic she has unleashed. Before the day is done, the twins find themselves drawn into a baffling adventure filled with uncanny happenings and secrets waiting to be uncovered. What begins as an ordinary birthday transforms into something far stranger, and the Grey Pumpkin holds secrets that will test the twins' courage and curiosity in equal measure. This is the kind of old-fashioned adventure story where children stumble upon mysteries far beyond their understanding and must rely on their wits to see them through. Perfect for readers who believe that the most extraordinary things often hide in the most ordinary packages, and that a birthday gift can change everything.
