Eighteen years have passed since the battlestar Galatica and its ragtag fleet of survivors began their epic journey to find the legendary planet Earth. Commander Adama has died, and the brash Colonial warrior Starbuck has disappeared during a recon patrol and is presumed dead. Confronted by a deadly force of Cylon warriors on the outside, and a rebellion led by the embodiment of evil aboard the battlestar, Apollo fights for his life, the survival of the fleet, and the ultimate fate of humanity itself.
