After four centuries of space travel Man was supreme. Human civilization had spread to hundreds of planets, and never, never had the colonists found a trace of another intelligent species. Humanity was alone, with the entire galaxy to command.

And then the unthinkable happened. An experimental ship, probing far beyond Earth's most distant outposts, discovered a new colonyand the colonists were not human.

An alien empire was advancing inexorably on Earth. Imperial Norgla believed they were alone in the galaxy, and that th stars were theirs to claim. Earth and Norgla would have to compromise—or both would be destroyed.
