A powerful alien ship. Heading to Earth. Intent unknown.
Bad, 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 tempts insiders of both factions. Instead of peace through cooperation, peace through conquest. 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 its crew threatens Earth.
