After a mysterious explosion destroyed her millionaire uncle’s yacht, Sandy Fuller and her tutor Jonas Withers were rescued by the strange inhabitants of the lost island of Mu, never seen before by other human eyes. They gave Sandy special powers in the fight against evil and arranged for her to be picked up by a passing liner. Back home she was forbidden from making any friends or she would lose her powers.
