Earth. The birthplace of human civilization. A civilization on the verge of collapse. While survivors on the planet struggle to fight back against the occupation force, the upper echelons of Earth's government – safely ensconced in the Thor's Hammer space station – remain mired in political infighting that seems fated to lead to disaster. Recovering from injury, Commander Finn Radko marshals his allies – including the newly-crowned War Matriarch of an alien race, Freyja Sigurdsson – to set in motion their ultimate end-game: the liberation of Earth. But the enemy armada has begun a redeployment that, if successful, would completely cut off Radko and his friends from Earth. The clock is ticking. The war has come home.
