The Dangerous Caves of Botown is a children's adventure/fantasy story set in the fictional seaside town of Botown, where Zach and Lucy Watson are on holiday with their parents. The year is 1995, and the adventure is sparked off by the family's interest in Botown Museum's fiftieth anniversary celebrations. These include a tour of the local dangerous caves where ancient artefacts were discovered during a dig in 1970. The Watsons join the tour and learn that Botown has a history of human settlement dating back to the earliest of times. Further exploration by the children and their friends, Ben and Cathy, leads them to an exciting adventure and the discovery of something amazing about the caves, which helps explain a mystery that has troubled inhabitants of Botown for centuries.
