It's all Calum's fault. When Calum made a model castle, he had no idea he and his grandmother would end up inside it...
and all because of one silly wish. Follow Calum and Grand back in time to a world of castles, knights, pages and spies in The Secret Weapon. Find out if bananas and chewing gum can help save them on their adventure.
