Cecilia Holland’s 1976 Floating Worlds is a standalone SF novel.
Thousands of years in the future, Earth is a polluted wasteland where to venture outside unprotected is to commit suicide. This is a lamentable state of affairs but not one that the anarchists running Earth, for very loose values of running, seem interested in fixing … or able to fix. The Moon, Mars, Venus, the Asteroids, and the Outer Planets, however, are all home to thriving human communities. All of which seem to be managing their affairs, and their environments, more successfully than is Earth.
Paula Mendoza is a doctrinaire anarchist, the last person one would expect to get drawn into government work. She has a rare skill, however, one that is of unique value to Earth’s Committee for the Revolution. Paula is multilingual.
