Dahak

For Lt. Commander Colin Maclntyre, it began as a routine training flight over the moon. For Dahak, a self-aware Imperial battleship, it began millennia ago when that powerful artificial intelligence underwent a mutiny in the face of the enemy. The mutiny was never resolved - Dahak was forced to maroon not just the mutineers but the entire crew on prehistoric Earth.  

Colin MacIntyre's life as a NASA astronaut might not have been exciting, but at least it was orderly. Unfortunately, he's been tapped for greater things, and he isn't too sure he likes it. First he was kidnapped by an ancient, self-aware starship masquerading as Earth's moon. Then he was drafted as its captain to suppress a 5,000-year-old mutiny. And then he had to mobilize the planet against the attack of an eons-old ancient menace dedicated to the eradication of all intelligent life in the galaxy! It's hard to blame him for feeling a little stressed....

Restoring the empire that had been destroyed 45 years earlier, Emperor Colin finds problems in the genocidal Achuutani and in his children, Sean and Harriet, who have been marooned on a hostile planet.
