The world has ended…. The war is only beginning.

An asteroid storm has obliterated the Earth. Billy and Linda West have built enough space-going arks to save a small number of people who now roam the void in search of a new home.

Desperate to find a safe haven, Billy makes a dangerous attempt to exceed the speed of light. When his plans go terribly wrong, the Wests' severely-damaged ship is separated from the fleet and left drifting near a mysterious planet.

This world's conditions are hospitable—but its inhabitants are not. Suddenly the Wests and their fellow survivors are caught in the middle of an ancient war between two brutal nations. Faced with horrific dangers, they are forced to choose a side just to survive.
