Earth, 2512 A.D. Humans have spread across the six arms of the Milky Way galaxy. The Unified Authority controls Earth's colonies with its military made up almost entirely of clones -- until civil war breaks out. Now the U.A. struggles to survive after a devastating attack cut its communications and left its fleets isolated...

But the rebel factions are warring among themselves, and Harris is contacted by a group that wants to return to the Unified Authority's command and protection -- and they want Harris to deliver their offer of allegiance.

Unable to resist the thrill of battle, Harris finds himself in the uniform of a U.A. Marine once more, leading a strike against the enemy. But the rebels have a powerful ally no one could have imagined...
