Empire From the Ashes

"Colin might have been forgiven for thinking that those were enough surprises for any one man, but there were a few other small problems. Like the deadly mutiny which had been raging longer than the human race had existed on Earth...and still wasn't over. Or like the millions of other starships, crewed by genocidal aliens dedicated to the extermination of all possibile competing life forms, which just happened to be headed straight towards Earth. Or like the interstellar empire whose aid offered humanity's only hope for survival...except for the minor fact that its last emperor and all of his subjects had died forty-five thousand years ago.".
