In 2026, the Earth faces an unexpected disaster. A supernova in the nearby Alpha Centauri system has apparently wiped out nearly every electronic component on the planet, leaving human civilization paralyzed. Phones don't work, transportation grinds to a halt, and essential services such as medical care are thrown back into the Stone Age. As the world tries to cope with this technological cut-off, a man dying of cancer begins a journey to save his life and that of his fellow patients, a master criminal escapes a sentence of “judiciary sleep,” a returning Mars expedition faces what looks like certain death, and U.S. president Saul Steinmetz strives to keep his country from falling apart. Author Charles Sheffield has taken a classic hard-SF concept, applied it to the real world, and created a gripping story of survival.
After the Nuclear Spasm in the 21st century, was extinct, save for a tiny remnant scattered in small, primitive space colonies. At first Solar Humanity had only one goal: survival. But when the battle for existence was won, humankind began moving outward in slow, multi-generation space ships, and as then millennia passed, planet-based civilizations emerged in many star systems. In the year 27,698 A.D, to these new worlds come the Immortals, beings with strange ties to ancient Earth, who seem to live forever, who can travel light years in days — and who use their strange powers to control the existence of ordinary mortals. On the planet Pentecost, a small group sets out to find and challenge the Immortals. But in the search they themselves are changed: as Immortals, they discover a new threat, not just to themselves, but to the galaxy itself.
The discovery of an ancient alien technology known as the Artifacts enables the human race to jump from galaxy to galaxy, but when a strange new Artifact emerges and changes all the other Artifacts, chaos ensues.
The Great War is over and humans have spread across the solar system, but mathematician Alex Ligon’s complex computer model has just predicted that humanity is inexplicably doomed within a century. At the same time, scientist Milly Wu has identified what appears to be an extraterrestrial signal, and the idiosyncratic genius Bat searches for weapons from the Great War to add to his collection, finding much more than he bargained for. Their stories and others are intertwined in this tightly plotted and thoroughly engaging follow-up to Sheffield’s . Nebula Award winner Sheffield distinguishes himself as a writer ...

Lionel Salkind was a rising musical star. His twin brother, Leo Foss, was a researcher in government work that he couldn’t talk about. Then the helicopter they were flying crashed. When he woke up, Lionel learned that both he and Leo had sustained fatal injuries, and he was only alive because the surgeon had used organs from Leo to repair Lionel’s slightly less damaged body. More than half of Lionel’s brain was gone, and had been replaced with Leo’s. Lionel, in fact, had become The book was written in 1982 and revised in 1998.

The sky is falling — again. Following up on 1998’s excellent , subjects planet Earth to yet another cosmic blast from the Alpha Centauri supernova. But while the blast that hit Earth in simply cooked the Southern hemisphere and knocked out unshielded technology with a flash of gamma rays, this wave promises to do some real damage, with a sleet of trillion-nuclei bundles moving at one-tenth the speed of light.Warned by the first catastrophe, Earth began building an electromagnetic shield out of the orbiting station to divert the incoming apocalypse. But not only will the storm come earlier than ...
It was just before Summertide, the time when the twin planets, Opal and Quake, would orbit closest to their sun, subjecting both — but Quake in particular — to vast tidal forces. And it was to be the most violent Summertide ever, due to the Grand Conjunction of the system’s stars and planets, something that happened only every 350,000 years.Access to the unstable Quake was supposed to be prohibited, but some very insistent travelers were determined to make the trip. Professor Darya Lang, who had made a career studying artifacts left by the long-vanished aliens called the Builders, had ...

Presenting the space adventures of Arthur Morton McAndrew, space-time expert and scientist extraordinaire, and his long-suffering companion, spaceship skipper Jeanie Roker. Jeanie first met McAndrew on a routine run to Titan and quickly learned he was a genius of the caliber of Newton or Einstein. When McAndrew invented a space drive that let frail humans survive hundreds of gravities of acceleration, he disappeared while testing it, and Jeanie had to find him, using a trail of cryptic messages he had left behind. That was the beginning of a beautiful friendship, in spite of the gray hairs that Jeanie began accumulating as a result of McAndrew’s impractical nature and his talent for getting himself into trouble with much more practical villains, such as…

His skill at blending hard science with fast-paced plotting and colorful characters makes this a first-rate SF adventure that belongs in most libraries.
Rob Merlin was the best engineer who had ever lived. That was why "The King of Space" had to have him for the most spectacular construction project ever — even though Rob was a potentially fatal threat to his power…Thus begins a breakthrough novel by the former President of the American Astronautical Society, about an idea whose time has come: a shimmering bridge between Earth and space that mankind will climb to the stars!Sound like fantasy? The concept has been in the literature of physics for over three decades, but only a writer with the scientific background of a Sheffield or a Clarke could bring the idea to life.
