Song of the Dolphin Boy

In the tiny fishing village of Stromhead, Finn sticks out like a sore thumb. Always told to keep away from the water, he's always felt out of place and as though something was missing until one day he dives in and finds that, swimming with dolphins, he feels completely at home. But Finn's new friends are in danger from the rubbish that floats out into the water, and now a supermarket is going to release thousands of balloons that could drift out to sea and cause even more damage! Can Finn help his dolphin friends?
