"Dick's best books always describe a future that is both entirely recognizable and utterly unimaginable."--The New York Times Book Review

When a repairman accidentally discovers a parallel universe, everyone sees it as an opportunity, whether as a way to ease Earth's overcrowding, set up a personal kingdom, or hide an inconvenient mistress. But when a civilization is found already living there, the people on this side of the crack are sent scrambling to discover their motives. Will these parallel humans come in peace, or are they just as corrupt and ill-intentioned as the people...

The story is set in the distant future, where humanity is at war with "Yuks," an alien life form which does not use mechanical spaceships nor constructions. Instead, it relies on life forms. The war has been going on for a long time, and humanity has not been able to come up with a solution against the life-form based ships and mines that the Yuks use. One day, a team of researchers led by Philip Kramer decide to build a spaceship which is powered by a human brain. They find the ideal candidate, Kramer's old professor, a dying man who volunteers to donate his brain to the project. A human...

Conger, the protagonist, is given a chance to get out of jail if he agrees to travel back in time and kill a man. He has agreed to kill a stranger he has never seen. He isn't concerned about getting the wrong man. He knows what the man looked like. There was no way he could make a mistake about his target's identity -- he has the man's skull under his shoulder.

No weapon has ever been frightful enough to put a stop to war -- perhaps because we never before had any that thought for themselves "They pasted Moscow again last night." Taylor nodded his head in approval. "Gave it a real pounding. One of those R-H bombs. It's about time." He sighed, drawing in the full comfort of the kitchen, the presence of his plump, attractive wife, the breakfast dishes and coffee. This was relaxation. And the war news was good, good and satisfying. He could feel a justifiable glow at the news, a sense of pride and personal accomplishment. After all, he was an...

Theoretically, you could find this type of humor anywhere. But only a topflight science-fictionist, we thought, could have written this story, in just this way. . . . Start here: It was quite by accident I discovered this incredible invasion of Earth by lifeforms from another planet. As yet, I haven't done anything about it; I can't think of anything to do. I wrote to the Government, and they sent back a pamphlet on the repair and maintenance of frame houses. Anyhow, the whole thing is known; I'm not the first to discover it. Maybe it's even under control. "All of his work starts with the...

The Captain peered into the eyepiece of the telescope. He adjusted the focus quickly. "It was an atomic fission we saw, all right," he said presently. He sighed and pushed the eyepiece away. "Any of you who wants to look may do so. But it's not a pretty sight." "Let me look," Tance the archeologist said. He bent down to look, squinting. "Good Lord " He leaped violently back, knocking against Dorle, the Chief Navigator. But when they got there, nothing moved or stirred. Everything was silent, dead. Only the gun showed signs of life . . . and the trespassers had wrecked that for all time....

"Well, Corporal Westerburg," Doctor Henry Harris said gently, "just why do you think you're a plant?" As he spoke, Harris glanced down again at the card on his desk. It was from the Base Commander himself, made out in Cox's heavy scrawl: Doc, this is the lad I told you about. Talk to him and try to find out how he got this delusion. He's from the new Garrison, the new check-station on Asteroid Y-3, and we don't want anything to go wrong there. Especially a silly damn thing like this

The wub stood sagging, its great body settling slowly. It was sitting down, its eyes half shut. A few flies buzzed about its flank, and it switched its tail. It sat. There was silence. "It's a wub," Peterson said. "I got it from a native for fifty cents. He said it was a very unusual animal. Very respected." "This? It's a pig A huge dirty pig " "Yes sir, it's a pig. The natives call it a wub." "A huge pig. It must weigh four hundred pounds." Franco grabbed a tuft of the rough hair. The wub gasped. Its eyes opened, small and moist. Then its great mouth twitched. A tear rolled down the...

The Terran system is growing and expanding all the time. But an old and corrupt Centaurian Empire is holding Terra down, as it encircles the Terran system and will not let the humans grow out of their current empire. For this reason Terra is at war with Proxima Centauri and is trying to find a way of breaking free from the Centaurian's hold upon them.
