Twins Nancy and Peter, with their friend Jolyon, are exploring caves in the South of France when they stumble upon a gang of kidnappers. In the confusion that follows the whole group becomes lost. They emerge at last into a very strange world and the children face a hard and desperate flight to safety.



I think this book is most likely to appeal to those with a reading age of 11 upwards. It is a book of magic and adventure. Enjoy!
