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 three challenges 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, Jr. , into prominence as a master of the inventive imagination -- long before he became the editor of Astounding/Analog and changed the field of science fiction forever!
