In effect Professor Newland declared that the curious astronomical phenomena of the previous November--the new "stars" observed, the two meteors that had fallen with their red and green light-fire--were all evidence of the existence of intelligent life on the planet Mercury. (An excerpt from chapter 1. )

There were nine major planets in the Solar System and it was within their boundaries that man first set up interplanetary commerce and began trading with the ancient Martian civilization. And then they discovered a tenth planet--a maverick! This tenth world, if it had an orbit, had a strange one, for it was heading inwards from interstellar space, heading close to the Earth-Mars spaceways, upsetting astronautic calculations and raising turmoil on the two inhabited worlds. But even so none suspected then just how much trouble this new world would make...

In "Tarrano the Conqueror" is presented a tale of the year 2430 A.D.--a time somewhat farther beyond our present-day era than we are beyond Columbus' discovery of America. My desire has been to create for you the impression that you have suddenly been plunged forward into that time--to give you the feeling Columbus might have had could he have read a novel of our present-day life. To this end I have conceived myself a writer of that future time, addressing his contemporary public. You are to imagine...

This famous Pohl story explores cybernetic robots and implanted personalities in a way that certainly expanded my way of looking at reality. Is that wall really real? or is it just kinda, sorta real? And who am I? The protagonist, Guy Burckhardt, wakes up screaming from a horrible dream of explosions, searing fire, choking gas and other terrible ways to die. But he wakes up so it must have been just a bad nightmare, right? To find out that piece of information you will need to listen to this inventive and scary story.

Trigger Argee was his closest associate—she means to find him. She's brilliant, beautiful, and skilled in every known martial art. She's worth plenty—dead or alive—to more than one faction in this obscure battle.

Layard was a curiosity to sociologists. The planet supported thriving tribes of natives but they were genderless. How could tribes form without families? But Gavin Duncan didn’t care. He had come to Layard to farm vua plants. Their berries cured mental illnesses and were one of the most expensive commodities in the galaxy. He was going to make his fortune if he could just keep the Cytha at bay, a big, dumb animal that could munch through 10 rows of vua in a night. Despite native superstitions he was going to have to hunt and kill the pest if he was to protect his crop...

Clifford Simak deals with the implications of time travel in his own unique way in this story. What if a group of guys did it on their own, without any help from government or industry? On a shoestring,so to speak? Would anyone believe them? What would you do if you could go back 150,000 years to a time when mastodons and saber toothed tigers roamed North America? And what happens when they run out of money? All these questions are explored in the usual humorous, wry Simak way in this story.

"I was one hundred miles from Nowhere—and I mean that literally—when I spotted this girl out of the corner of my eye. I'd been keeping an extra lookout because I still expected the other undead bugger left over from the murder party at Nowhere to be stalking me." In a Post apocalyptic world, the few people left must be strong. And must not hesitate to kill. Of course, killing another Deathlander was one of the chief pleasures and urges of all the solitary wanders in this vast wasteland. Kill and kill again. But this other was a girl and that brought up the second great urge: sex. Which was it to be today? Perhaps both?

A classic locked room mystery, in a not-so-classic setting. (Intro by Karen Savage)

They were a traveling group of Shakespearean players; perfectly harmless, right? Wrong. For one thing, why did they have spacemen costumes in their wardrobes, right next to caveman ones? Why was the girl in charge of backstage suffering from amnesia and agoraphobia? No Great Magic is needed to perform the plays they put on, but sometimes great science. No matter where, or when.

The star Mira was unpredictably variable. Sometimes it was blazing, brilliant and hot. Other times it was oddly dim, cool, shedding little warmth on its many planets. Gresth Gkae, leader of the Mirans, was seeking a better star, one to which his "people" could migrate. That star had to be steady, reliable, with a good planetary system. And in his astronomical searching, he found Sol.With hundreds of ships, each larger than whole Terrestrial spaceports, and traveling faster than the speed of light, the Mirans set out to move in to Solar regions and take over...

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, into prominence as a master of the inventive imagination.

As Earth's faster-than-light spaceship hung in the void between galaxies, Arcot, Wade, Morey and Fuller could see below them, like a vast shining horizon, the mass of stars that formed their own island universe. Morey worked a moment with his slide rule, then said, "We made good time! Twenty-nine light years in ten seconds! Yet you had it on at only half power...." Arcot pushed the control lever all the way to full power. The ship filled with the strain of flowing energy, and sparks snapped in the air of the control room as they raced at an inconceivable speed through the darkness of intergalactic space...

The famous scientific trio of Arcot, Wade and Morey, challenged by the most ruthless aliens in all the universes, blasted off on an intergalactic search for defenses against the invaders of Earth and all her allies.

Mighty battles between huge space armadas were but skirmishes in the galactic war, as the invincible aliens savagely advanced and the Earth team hurled bolt after bolt of pure ravening energy--until it appeared that the universe itself might end in one final flare of furious torrential power....

“Mr. Benson sees the world, four or five generations hence, free at last from all minor quarrels, and ranged against itself in two camps, Humanitarianism for those who believe in no divinity but that of man, Catholicism for those who believe in no divinity but that of God.” This apocalyptic novel from the early 1900's is sometimes deemed one of the first modern dystopias.

In a former book, called "Lord of the World," I attempted to sketch the kind of developments a hundred years hence which, I thought, might reasonably be expected if the present lines of what is called "modern thought" were only prolonged far enough; and I was informed repeatedly that the effect of the book was exceedingly depressing and discouraging to optimistic Christians. In the present book I am attempting -- also in parable form -- not in the least to withdraw anything that I said in the former,...
