Thousands of years in the past, three colony ships, the Britannia, Australia, and America, fled from Earth to escape dictatorial rule and a coming nuclear war and set out to find habitable planets for settlements far from Earth. The planet the Britannia Colony Ship settled has been destroyed by an advanced alien civilization. Its cities were laid waste and burned to the ground by orbital bombardment from a thousand alien warships. Many of Britannia's survivors were moved to, Melbourne, the second colony which was founded by the Australia, but many chose to remain behind; they died when the aliens returned a year later and killed every one still alive on the planet. Grady and Taffy Henricks, along with Rory and Abby Dunhan, are committed to distracting Earth and the aliens from discovering Melbourne's location. For over two years they have been using two small advanced warships which Grady developed to harass their enemies and keep them fighting against each other. However, the aliens have discovered Earth's location and the war between them is taking on a new direction and intensity. The coming confrontation is going to be cataclysmic. The whereabouts of the third colony ship, the America, has remained a mystery. No one knows where in the Milky Way it went or even if it survived; Grady Henricks intends to go and find out. There are two dangerous civilizations that could destroy Melbourne if either of them discovers its existence. The aliens that destroyed Britannia, as well as Earth, have huge fleets of warships that greatly outnumber the forces Melbourne has available to defend it; construction of new warships is currently the prime focus of their government. Finding America is going to make the situation even more dangerous.
