Seven years ago, the remarkable Stavenger family made Moonbase a reality. Now a substantial community lives, labors and flourishes under the leadership of Doug Stavenger, thanks to the wonders of nanotechnology; virus-size machines that can build, refine, cure, create and destroy. But the science that sustains the young off-Earth colony has been declared illegal by the home planet's rulers. And one man with the power to dictate policy is determined to lay claim to Stavenger's peaceful city . . . or to obliterate it if he can't have it.
Seven years ago, Moonbase rose up like the phoenix out of the luinar dust, overcoming the bitter enmity of Earthside foes for the right to exist. Now it's total war.
