Piloting a space ship called for nerves of steel and an instantaneous set of reflexes; in addition there was a tougher requirement…

His choice would govern a boy’s fate—and, incidentally, Earth’s entire future.

It was in wide-eyed horror that Roy Gardner heard the news from the Chief of Security. In just sixty-seven years the Earth would be totally destroyed by the planet Lurion.That data had been compiled by the invincible computer. With unwavering faith in the machine, humans had only one thing to do—destroy Lurion first.And the man to do the job was Gardner. If he did it successfully the blood of billions would be on his hands; if he fouled up he would be the worst traitor in Terrestrial history. And not even he knew which course he would pursue when he finally learned that even the all-wise machine had not known all the right answers.

The death-stars had come, and they had kept on coming for hundreds of thousands of years, falling upon the Earth, swept upon it by a vagrant star that had passed through the outer reaches of the solar system. They brought with them a time of unending darkness and cold. It was a thing that happened every twenty-six million years, and there was no turning it aside. But all that was done with now. At last the death-stars had ceased to fall, the sky had cleared of dust and cinders, the sun’s warmth again was able to break through the clouds. The glaciers relinquished their hold on the land; the Long Winter ended; the New Springtime began. The world was born anew.Now each year was warmer than the last. The fair seasons of spring and summer, long lost from the world, came again with increasing power. And the People, having survived the dark time in their sealed cocoons, were spreading rapidly across the fertile land.But others were already there. The hjjks, the somber cold-eyed insect-folk, had never retreated, even at the time of greatest chill. The world had fallen to them by default, and they had been its sole masters for seven hundred thousand years. They were not likely to share it gladly now.
