Milly Niceman is a fourteen-year-old girl who has grown frustrated with her mother's attempts to curtail her tomboyish nature. Her mother, Doris, believes that Milly's actions are inappropriate for a girl, and that she'd be better off showing more interest in dances and dresses. When her best friend's younger brother, Malcolm, sells her a spell that will grant her deepest wish, that will only work with the upcoming eclipse. Milly jumps at the chance. She performs the spell, and believes that it has failed. The next morning, Milly discovers that not only was the spell successful, but turned her into a boy. She tells her family about what happened, and to her surprise, her father encourages her to explore her new masculinity.
