Dolphin Island : a story of the people of the sea

A seventeen-year-old boy becomes involved in communication experiments with dolphins off the Great Barrier Reef. "'It was the first time Johnny had ever felt utter, unreasoning panic. His limbs had turned to jelly; he could hardly breathe for the weight pressing on his chest.' Johnny Clinton has stowed away - almost by accident - on an enormous hovership. But even before his hide-out is discovered, the Santa Anna is shipwrecked, and Johnny finds himself at the beginning of an exciting and dangerous adventure. Dolphins, killer whales, a hurricane and an underwater conspiracy all add up to a thrilling tale, set in the twenty-first century, from a master of science fiction."--Back cover
