Sam the Seagull: Manchester by the Sea is a true story of three boys: Brian, John, and Cliffy, who lived by the ocean. It was the day of their big adventure to Dana's Island. They explored seaweed, shells, sea glass, and more. When they stumbled on a small, fuzzy, little chick seagull, they knew, instinctively, that they had to keep it safe. Their lives changed that day. Brian's ducks, Daffney and Drake took on the role of foster parents, and the adventures began and lasted for forty years.
