Jenny Oldfield

A family marooned on an island finds loveable dolphins to help them survive: classic adventure from million-copy-selling Jenny Oldfield. Shipwrecked near a tiny island in a vast ocean, the Fisher family are guided to safety by a small pod of dolphins. Fleur, Alfie, Mia and their parents must learn to build shelter, find fresh water and hunt for food. Each of the children forms a special bond with one of the family of dolphins.
Fleur adores the fun-loving, tail-walking Jazz. Mia names her dark-grey dolphin friend Stormy. And Alfie is saved from the shipwreck by Pearl, who always looks out for him. The family have relied on their pod of dolphins for everything - but they're ready to come to the rescue when, this time, it's their dolphin friends who need the kids' help! Jenny Oldfield strikes gold in this beautifully illustrated, exciting adventure story, the fifth in the Dolphin Island series.
