In this story set in rural Mexico, a young girl named Rosalinda awakens one night to find that a Night Man has taken the lemons from her beloved tree. Soon after this event, the tree begins to sicken. Rosalinda asks her parents, some neighbors, and her abuela (grandmother) for advice. When her grandmother tells Rosalinda about La Anciana—the Old One—the girl begins to search for her. Just when Rosalinda discovers the Night Man selling her lemons in the market, La Anciana appears. “Perhaps he had a need,” the Old One tells Rosalinda and offers instructions for healing the tree. The story ends as Rosalinda gives away the beautiful lemons that her healthy tree now yields, including one to the Night Man whom she tells to plant the seeds while the lemon moon is still in the sky.
