That bought them some time, but wasn't nearly far enough away. The Spacers knew it would come to a bad end. The only question was how, when, and would they survive it? The only refuge was in the stars where they had friends.

It is 2076: Lancer, Earth’s first starship, is on a mission to find interstellar civilizations.
