A Story of the People of the SeaThe adventure begins when Johnny, who has run away from home and hidden aboard an intercontinental hovership, is shipwrecked in the middle of the South Pacific Ocean. Stranded on a raft, and in an apparently hopeless situation, he is propelled by a pack of dolphins towards an island in the Great Barrier Reef, a famous centre for Dolphin Research.Professor Kazan, the director of research, shares Johnny's bewilderment as to the reason for the dolphin rescue operation and arranges for Johnny to stay on the island to assist in unravelling the mystery. In the chapters that follow, Johnny learns how to communicate with dolphins, explores the coral reef, goes skin-diving at night, survives a fearful hurricane, unearths a horrifying underwater conspiracy, and, in an intensely exciting final episode, makes a dangerous 100 mile tip on surfboard towed, turn and turn about, by his two closest dolphin friends.
