In July 2049, Dr. Thomas McKinsey and a small band of scientists rebelled against the recently installed Congress-In-Council to declare the moon a republic. Six months later, McKinsey’s followers were dead and he was dying. With the world below him entering a prolonged global struggle, McKinsey programmed the computers of Tranquility to continue his strategic vision, a plan to establish world unity even at a terrible cost. As an afterthought, he instructed the machines to raise the colony’s only surviving resident, a baby destined to grow up on an abandoned moonbase with computers as his only companions. Now it’s August 2070 and freedom has at last been won for the rebel Lunar Republic, but is time running out on Earth’s future? With an alien invasion fleet only a few years away, there are still space ships to build and a world to unite. But when misunderstandings occur and old enemies reappear, Grey Waters must face his greatest challenge yet. Is it a challenge he will need to face alone?
