The book makes several references to Hazel as an influential figure in founding the Lunar colony. Fourteen years later, Heinlein published "The Moon Is a Harsh Mistress", which tells the story of the Lunar revolution, including a small but vital role that Hazel Stone played as a child (no specifics of this role are mentioned in "The Rolling Stones"; she is portrayed here simply as a "founding Father"). Hazel, Castor, and Pollux reappear in "Number of the Beast" and "The Cat Who Walks Through Walls". Hazel, alone, appears in "To Sail Beyond the Sunset".
