They first appear as a series of dots on astronomical plates, heading from Saturn directly toward Earth. Since the ringed planet carries no life, scientists deduce the mysterious ship to be a visitor from another star. The world's frantic efforts to signal the aliens go unanswered. The first contact is hostile: the invaders blast a Soviet space station, seize the survivors, and then destroy every dam and installation on Earth with a hail of asteriods.

The Mote In God's Eye is their acknowledged masterpiece, an epic novel of mankind's first encounter with alien life that transcends the genre. No lesser an authority than Robert A. Heinlein called it "possibly the finest science fiction novel I have ever read".

Welcome to Ringworld, an intermediate step between Dyson Spheres and planets. The gravitational force created by a rotation on its axis of 770 miles per second means no need for a roof. Walls 1,000 miles high at each rim will let in the sun and prevent much air from escaping. Larry Niven's novel, Ringworld, is the winner of the 1970 Hugo Award for Best Novel, the 1970 Nebula Award for Best Novel, and the 1972 Ditmars, an Australian award for Best International Science Fiction.

Already cited on the floor of Congress and discussed in the corridors of the Pentagon as a book all Americans should read, One Second After is the story of a war scenario that could become all too terrifyingly real.

Winner of the 1961 Hugo Award for Best Novel and widely considered one of the most accomplished, powerful, and enduring classics of modern speculative fiction, Walter M. Miller’s A Canticle for Leibowitz is a true landmark of 20th-century literature—a chilling and still-provocative look at a postapocalyptic future.

The cabin had always been a special retreat for Isherwood Williams, a haven from the demands of society. But one day while hiking, Ish was bitten by a rattlesnake, and the solitude he had so desired took on dire new significance. Ish headed home when he finally felt himself again—and noticed the strangeness almost immediately. No cars passed him on the road; the gas station not far from his cabin looked abandoned; and he was shocked to see the body of a man on the roadside near a small town. Without a radio or phone, Ish had no idea of humanity’s abrupt demise.

This true modern masterpiece is built around the two fateful words that make up the title and herald the end - “Alas, Babylon.” When a nuclear holocaust ravages the United States, a thousand years of civilization are stripped away overnight, and tens of millions of people are killed instantly.

For dinosaurs, it was a big rock. For humans: Coronal Mass Ejection (CME). When the Earth is hit by the greatest CME in recorded history (several times larger than the Carrington Event of 1859), the combined societies of the planet's most developed nations struggle to adapt to a life thrust back into the Dark Ages. In the United States, the military scrambles to speed the nation's recovery on multiple fronts including putting down riots, establishing relief camps, delivering medical aid, and bringing communication and travel back on line. Just as a real foothold is established in retaking the skies (utilizing existing commercial aircraft supplemented by military resources and ground control systems), a mysterious virus takes hold of the population, spreading globally over the very flight routes that the survivors fought so hard to rebuild.

They were armed and highly trained. But then, Barb was kidnapped. The kidnappers didn’t know why Conor was known as The Mad Mick. They didn’t know the fear and respect his name invoked in the shadowy underworld of covert operations. They didn’t know that when it came to protecting his family, he was without conscience, without compassion, and without equal. But they would soon find out.

This is the way the world ends: with a nanosecond of computer error in a Defense Department laboratory and a million casual contacts that form the links in a chain letter of death. And here is the bleak new world of the day after: a world stripped of its institutions and emptied of 99 percent of its people. A world in which a handful of panicky survivors choose sides - or are chosen.
