S. Lewis’s adult religious books, a repackaged edition of the revered author’s definitive collection of short fiction, which explores enduring spiritual and science fiction themes such as space, time, reality, fantasy, God, and the fate of humankind.From C.S. Lewis—the great British writer, scholar, lay theologian, broadcaster, Christian apologist, and author of Mere Christianity, The Screwtape Letters, The Great Divorce, The Chronicles of Narnia, and many other beloved classics—comes a collection of his dazzling short fiction.This collection of futuristic fiction includes a breathtaking science fiction story written early in his career in which Cambridge intellectuals witness the breach of space-time through a chronoscope—a telescope that looks not just into another world, but into another time. As powerful, inventive, and profound as his theological and philosophical works, The Dark Tower reveals another side of Lewis’s creative mind and his longtime fascination with reality and spirituality. It is ideal reading for fans of J. R. R. Tolkien, Lewis’s longtime friend and colleague.

    There are some who want to improve it. There are some who want to eradicate it. And there are others who just want to exploit it.When a young scientist is caught improving Nexus, he’s thrust over his head into a world of danger and international espionage – for there is far more at stake than anyone realizes.From the halls of academe to the halls of power, from the headquarters of an elite US agency in Washington DC to a secret lab beneath a top university in Shanghai, from the underground parties of San Francisco to the illegal biotech markets of Bangkok, from an international neuroscience conference to a remote monastery in the mountains of Thailand – Nexus is a thrill ride through a future on the brink of explosion.

    Bob Johansson has just sold his software company and is looking forward to a life of leisure. There are places to go, books to read, and movies to watch. So it's a little unfair when he gets himself killed crossing the street. Bob wakes up a century later to find that corpsicles have been declared to be without rights, and he is now the property of the state. He has been uploaded into computer hardware and is slated to be the controlling AI in an interstellar probe looking for habitable planets. The stakes are high: no less than the first claim to entire worlds. If he declines the honor, he'll be switched off, and they'll try again with someone else. If he accepts, he becomes a prime target. There are at least three other countries trying to get their own probes launched first, and they play dirty. The safest place for Bob is in space, heading away from Earth at top speed. Or so he thinks. Because the universe is full of nasties, and trespassers make them mad - very mad.

    But Frampton and Carly are highly advanced (if bumbling) extraterrestrials. And boy, do they have news. The entire cosmos, they tell him, has been hopelessly hooked on humanity’s music ever since “Year Zero” (1977 to us), when American pop songs first reached alien ears. This addiction has driven a vast intergalactic society to commit the biggest copyright violation since the Big Bang. The resulting fines and penalties have bankrupted the whole universe. We humans suddenly own everything—and the aliens are not amused. Nick now has forty-eight hours to save humanity, while hopefully wowing the hot girl who lives down the hall from him.

    The title is a play on words, one meaning "the force which pulls" & the other being "extremely serious or important". It was serialized in Astounding Science Fiction, 4–7/53. Its 1st cloth publication was in '54. It was 1st published in paper in '58. Along with the novel itself, many editions (& most recent editions) of the book also include Whirligig World, an essay on creating the planet Mesklin that was published in the 6/53 Astounding. He published two sequels, a '70 novel called Star Light & a '73 short story called Lecture Demonstration. Mission of Gravity was nominated for a Retro Hugo Award for '54.For a profit & adventure Barlennan would sail thousands of miles across uncharted waters, into regions where gravity played strange tricks. He'd dare the perils of strange tribes & stranger creatures--even dicker with those aliens from beyond the skies, though the concept of another world was unknown to the inhabitants of the planet of Mesklin. But in spite of the incredible technology of the strangers & without regard for their enormous size, Barlennan had the notion of turning the deal to an unsuspected advantage for himself--a considerable enterprise for a being very much resembling a 15" caterpillar!
