William Taylor lives with his parents in Allymera Bay, famous for its spectacular sunsets and beautiful beaches. He's enjoying his summer because he gets to spend plenty of time out on the water, swimming and surfing. He knows these waters like the back of his hand-or so he thinks.
One day, he befriends two very interesting sea creatures named Silva and Bubbles-and they need his help. Suddenly, William's usually quiet world is turned upside down by his new friends. During this strange and beautiful encounter, William makes a promise to help them save Delphi Island, their home. And in the adventure they share, an unusual friendship is born.
