George is about to spend his third Christmas without his mum. Since she died, George’s life has felt dull and grey; his dad has thrown himself into his work and has no time for family, and definitely no time for Christmas. Then, George stumbles across Marley’s Curiosity Shop. There he finds a mysterious snow globe, which – though George can’t quite understand how – appears to show a scene from George’s past. A Christmas in which he and his family were together, and happy. That night, George and his dad are swept on an adventure to three Christmases – past, present, and future. With help from new friends, and just a touch of magic, can they begin living life in full colour again?
