Mizora: A Prophecy - Mary E. Bradley

A woman discovers a hidden, all-female utopian society located within the Earth’s interior. The inhabitants of Mizora have achieved scientific, social, and moral perfection through education, cooperation, and the eradication of crime and poverty. The narrator learns about their advanced technology and egalitarian ideals, which starkly contrast with the flawed world above. Ultimately, the story serves as both a visionary exploration of female potential and a critique of 19th-century gender and social inequality.
