Dahak Series by David Weber

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.

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. Dahak has been helplessly waiting as the descendants of the loyal crew regressed while the mutineers maintained control of technology that kept them alive as the millennia passed. But now Dahak's sensors indicate that the enemy that devastated the Imperium so long ago has returned--and Earth is in their path. For the sake of the planet, Dahak must mobilize its defenses. And that it cannot do until the mutineers are put down. So Dahak has picked Colin Maclntyre to be its new captain. Now Maclntyre must mobilize humanity to destroy the mutineers once and for all--or Earth will become a cinder in the path of galactic conquest. less

For really tough jobs, Emperor Colin, the first of that name, is your man. The only person in the galaxy ever to stop the genocidal Achuutani, he went on from there to resurrect an empire that died fourty-five thousand years ago. He's still got a few problems - like a traitor out to murder him and three-quarters of a billion of his subjects - but if anyone can handle the job, it's Colin. But the rest of the galaxy better brace itself, because his progeny are on the way... moreFor really tough jobs, Emperor Colin, the first of that name, is your man.

But the rest of the galaxy better brace itself, because his progeny are on the way. Not that Sean and Harriet aren't nice kids; it's just that they've had a bad day.They're a long way from home, marooned with a blown up starship that's left them stranded on a theocratic world of gun powder and pikes, and Mother Church of that world doesn't like them very much. In fact, she's declared them demons, proclaimed Holy War, marshalled the Holy Host, and ordered them exterminated. You might think that things look pretty bleak for the kids, but in reality it's Mother Church that's in trouble - because Sean and Harry are chips off the old block - and they're about to get angry... less
