Earth, 2508 A.D. Humans populate the six arms of the Milky Way Galaxy. The oppressive Unified Authority controls Earth's colonies with an iron fist, stamping out revolt with a powerful military made up almost entirely of expendable, mass-produced clones.
Private First Class Wayson Harris was raised in a Unified Authority orphanage among thousands of clones, bred to be the ultimate soldiers. But unlike the other Marines, programmed to obey first and think later, Harris has a mind of his own. When he fends of an attack from a rogue general, Harris is thrust into the middle of a galactic conflict that forces him to question his existence as a weapon of the U.A, and the cost of rebellion.
