An enormous, mysterious box descends upon smalltown Minnesota, spelling trouble for the world, in this classic adventure from a Science Fiction Grand Master. Forestry student Jerry Conklin is fly-fishing when something huge lands on his car, crushing it into the earth. It looks like a big black box—about fifty feet high and two hundred feet long—and the object stirs up quite a commotion among the townspeople of Lone Pine, Minnesota. One of them even shoots at it—and quickly pays for it with his life. Around the country, people scramble to determine what exactly the box is. Is it a machine? Or maybe a sentient being? What does it want? They have no way of knowing. Jerry, meanwhile, has firsthand knowledge after the visitor abducts him. Then, just as he discovers it is a living, intelligent creature, it releases him into the darkness of night. As Jerry searches for a way back to civilization, more visitors descend upon Earth. They seem harmless enough. Then they begin eating trees, and that’s only the beginning . . . Praise for The Visitors “One of the most engaging novels of alien invasion ever written.” —Library Journal

A volume of eleven stories from the Hugo Award–winning science fiction author that explore inner space, future worlds, and the peculiar lives of robots. One of the twentieth century’s most pioneering science fiction authors, Clifford D. Simak had a special fondness for robots. Not only did these thinking machines represent the boundless possibilities of technology, they also had the potential to bring—in his words—“the kindness and the courage that I thought were needed in the world.” The stories in this volume offer a variety of Simak’s unique robot visions. In “Lulu,” a robot built for planetary exploration takes on a female identity, causing unforeseen challenges for her three-man crew. An examination of an unknown planet reveals the celestial body to be a single, gigantic computer whose origins and purpose are a mystery, in “Limiting Factor.” And in the title story, Simak returns to his longest-running robot character, Jenkins, who reflects on all that has come and gone one last time. Each story includes an introduction by David W. Wixon, literary executor of the Clifford D. Simak estate and editor of this ebook.

In this classic novel by the Science Fiction Grand Master, a writer searching for explanations uncovers the existence of mutants and multiple Earths: “First-rate Simak” (The New York Times). Author Jay Vickers would like nothing more than to be left alone so he can finish his next book. But “there’s something strange going on,” as his peculiar neighbor, Horton Flanders, says. For instance, the market is filling with new inventions that supposedly last forever—cars, razors, cigarette lighters, and more. Individuals and whole families are disappearing. Soon, even Mr. Flanders vanishes—but not before leaving Vickers a note. Following Flanders’s advice, Vickers travels to his childhood home, where he makes a fantastic discovery. It is a mere child’s toy, a brightly colored whistling top. But for Jay Vickers, it leads to other worlds and answers all his questions. What happened to all the vanished people? Who is behind these helpful inventions? And what sort of being would want to stop them. . . ? “Unforgettable.” —New York Herald Tribune “Solid entertainment, with plenty of startling plot twists.” —The Magazine of Fantasy & Science Fiction “Some of the most ingenious plot twists in recent science-fiction.” —Galaxy

Adventurers journey into the foreboding unknown regions of outer space in these two classic science fiction tales from the Hugo and Nebula Award–winning author. The Trouble with Tycho Prospecting on the moon is grim, dangerous, and usually unrewarding. Most greenhorns don’t know that until after they arrive, and Chris Jackson is no exception. He put everything he owns, and then some, into this venture, and he’ll be ruined if he fails. Jackson’s last chance at success is hidden in the uncharted crater Tycho—where three expeditions have already disappeared. Jackson, a beautiful immigrant, and a visiting doctor set out to find their fortunes . . . and discover whether the terrifying rumors of what lurks within Tycho are true. Cosmic Engineers “Upon you and you alone must rest the fate of the universe. You are the only ones to save it.” Thus spoke the mysterious Cosmic Engineers to a small group of human beings on the rim of the Solar System. Courageously journeying beyond uncharted stars, somewhere in the vastness of the galaxy, they will meet the greatest challenge of their lives—the catastrophic fury of the Hellhounds of Space.
