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.
