The Triumvirate — John W. Campbell

THREE AGAINST THE STARS A sky pirate armed with superior weapons of his own invention.... First contact with an alien race dangerous enough to threaten the safety of two planets.... The arrival of an unseen dark sun whose attendant marauders aimed at the very end of civilization in this Solar System.... These were the first three challenges of many that tested the skill and minds of the brilliant team of scientist-astronauts Arcot, Wade, and Morey. Their initial adventures are a classic of science-fiction which first brought the name of their author, John W. Campbell, into prominence as a master of the inventive imagination. Contains the complete adventures of the Triumvirate, including Pirates Preferred, Solarite, The Black Star Passes, Islands of Space, and Invaders from the Infinite.
