An international colony ship has left an exhausted Earth, headed for a distant planet in the Epsilon Eridani system. Thirteen generations will be born on this vessel before it reaches its destination, each generation a steward of the hopes and ideals of the human species.
For six generations everything has gone as planned.
Now, just as a new command team takes control of the ship, a terrible mystery emerges that will threaten the entire mission. The commanders of Gen7 are about to discover that everything is not as it seems, and the fate of the human species will hang on the choices they make.
