Finn has always been different, and in the tiny fishing village of
Stromhead he sticks out like a sore thumb. Always told to keep away from
the water, he's felt that something was missing until one day he dives
in and finds that, swimming with the dolphins, he feels completely at
home. But his new friends are in danger of being injured by 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. Desperate to help the dolphins, Finn goes to the Lighthouse
Crew, a group of kids who have always left Finn out. Will they be able
to set aside their differences to save the dolphins? And what will Finn
discover about his past along the way? A moving adventure about the
impact of plastic pollution on our seas, and the campaigning power of
friendship.
