Invaders from the Infinite

The alien spaceship was unthinkably huge, enormously powerful, apparently irresistible. It came from the void and settled on Earth, striking awe into the hearts of all who saw it. Its mission, however, was not conquest -- but a call for help! First contact was a job for the brilliant team of scientists, Arcot, Wade, and Morey. And what they received was an offer of an alliance against an invading foe so powerful that no known force could turn it back! John W. Campbell's INVADERS FROM THE INFINITE is a veritable odyssey of the universe, exploring world after world and uncovering cosmic secret after cosmic secret. Here is a classic space opera that may never be surpassed!
