A sequel to Coral Reef Castaway, this story of modern piracy continues the adventures of 16 year old Con and his old friend Ginty. Manning their own ship the Con-Ginty, the two start out on a world cruise from the South Sea Islands, only to be captured by three crooks intent on stealing a fortune of pearls from the Wahito, a pearling lugger. When the crooks' plan goes awry and the Wahito sinks, Con and Ginty are forced to camouflage their ship and go ashore on a deserted island with their captors. Al Deen, who is obsessed with retrieving the pearls now on the ocean floor, compels Con to dive for them. Con and Ginty devise several exciting plans of escape, all of which fail, until Con's cleverness finally outwits the bandits and brings about their eventual capture. Diving sequences are described with the accuracy of realistic experience. Cyclones, underwater adventure and intriguing plans and counter-plans, all treated in an exuberant fast-moving style, create a tale of breathless suspense guaranteed to please youngsters (especially boys) from 11 to 13.
