Five on Brexit Island is a parody novel from the Enid Blyton for Grown Ups series, aimed at adult readers. The book uses the familiar characters of the Famous Five—now adults—to satirize the political and social discussions surrounding Brexit. The plot takes the five back to Kirrin Island, where their differing opinions on leaving the European Union lead to a humorous, exaggerated, and often absurd set of arguments and scenarios, commenting on contemporary British life.
