Uranus

Ben Bova, author of Earth, continues his exploration of the future of a human-settled Solar System with the science fiction action adventure Uranus, the first of his Outer Planets trilogy.
On a privately financed orbital habitat above the planet Uranus, political idealism conflicts with pragmatic, and illegal, methods of financing. Add a scientist who has funding to launch a probe deep into Uranus's ocean depths to search for signs of life, and you have a three-way struggle for control.
