Invasion 2132

A powerful alien ship. Heading to Earth. Intent unknown.
Bad enough, mission control lost contact with the interstellar explorers on Concordia. Worse, mission control now detects an unknown ship leaving the Alpha Centauri system. Heading to Earth at relativistic speeds. Driven by engines more potent than anything humans ever built. Silent about its purpose. Its crew unknown.
Leclerc, head of mission control, knows what he must do. If the ship comes to conquer or destroy Earth, the planet has only one chance. Its rival factions must set aside their cold war. They must turn their weapons of mass destruction to the common good. They must come together to prepare a mutual, desperate defense.
But powerful alien technology could give one faction a military edge over the other. Enough to risk blowing up the world for a chance to conquer it.
Leclerc must do more than find common ground with his former foes. He must face the lust for power of shadowy figures on his own side.
All the while not knowing who flies the alien ship.
Not knowing why they threaten Earth.
