John Varley writes science fiction about identity, gender, artificial environments and human societies reshaped by advanced technology. The Ophiuchi Hotline imagines a solar system where humanity survives away from an alien-controlled Earth and where cloning and body change make personal identity unusually fluid. The Gaea trilogy begins with Titan, sending explorers into a vast living habitat orbiting Saturn, while Steel Beach and The Golden Globe return to a future lunar society with extensive body modification and artificial intelligence. Varley's fiction is inventive, fast and comfortable with radical social change. It fits classic science fiction, posthuman fiction, space habitats and speculative stories about gender and identity.
