Written in 1963 and set in 21st century, a cargo hover ship makes an emergency stop in the Midwest for repairs.  Johnny Clinton, adventurous teenager, sneaks on board. A day later the craft is shipwrecked in the southern Pacific Ocean and starts to sink. The crew, unaware of the stowaway, leaves on a lifeboat. Johnny climbs onto a large piece of debris and is rescued by a pod of dolphins who push his raft 100 miles to an island in the heart of Australia’s Great Barrier Reef. There, Johnny meets the brilliant and eccentric Professor Kazan, who has dedicated his life to the study of dolphin communication. Johnny’s adventures include killer whales, hurricanes and an underwater conspiracy. Cover art by Christine Mowlan. Illustrations by Robin Anderson.
