Seemore the Seagull is a loveable people-watcher who observes the behavior of the diverse beach-goers on Revere Beach. He wants everyone to get along no matter what color, language, shape, or size. He becomes very upset when he sees some children argue and fight about sharing sand toys and destroying each other's sandcastles. He helps them learn to cooperate, and together they build a castle that makes them all happy. By listening or reading the story, young children learn respect for diversity and the benefits of sharing and cooperation. The illustrations and photos in the book capture the essence of historic Revere Beach, the first public beach in the United States.
