Galactica Discovers Earth — Glen A. Larson; Mike Resnick

GALACTICA DISCOVERS EARTH

Galactica was trapped! A Cylon warfleet was lurking just a lightjump away. And Earth -- hopelessly primitive! -- was completely unaware that the renegade Xaviar was rearranging history to make the planet into his private empire...

Only Captain Troy and Lieutenant Dillon knew just how dangerous Earth's predicament was. And if they had to save the ancient homeworld single-handedly -- well, that was a warrior's job!
