Sequel to Moonrise Ben Bova's extraordinary Moonbase Saga continues with a breathtaking near-future adventure rich in character and incident. The action begins seven years after the indomitable Stavenger family has realized its cherished dream of establishing a colony on the inhospitable lunar surface. Moonbase is now a thriving community under the leadership of Doug Stavenger, a marvel of scientific ahievement created and supported by nanotechnology: virus-size machines that can build, cure, and destroy. But nanotechnology has been declared illegal by the home planet's leaders. And a powerful despot is determined to lay claim to Stavenger's peaceful city...or obliterate it, if necessary. The people of Moonbase--a colony with no arms or military--must now defend themselves from earth-born aggression with the only weapon at their disposal: the astonishing technology that sustains their endangered home.
