The Peace War


Book Description

First in a quintessential hard-science fiction adventure, Hugo Award-winning author Vernor Vinge's The Peace War follows a scientist determined to put an end to the militarization of his greatest invention--and of the government behind it. The Peace Authority conquered the world with a weapon that never should have been a weapon--the "bobble," a spherical force-field impenetrable by any force known to mankind. Encasing governmental installations and military bases in bobbles, the Authority becomes virtually omnipotent. But they've never caught Paul Hoehler, the maverick who invented the technology, and who has been working quietly for decades to develop a way to defeat the Authority. With the help of an underground network of determined, independent scientists and a teenager who may be the apprentice genius he's needed for so long, he will shake the world.

A Pause in Space-Time (a Stasis Story #1)


Book Description

This novella length hard Sci-Fi book begins the "Stasis Stories," a series of tales from the near future. They tell us about Kaem Seba, a sickly and financially destitute young man who uses his extraordinary math talents to work out a way to stop time within limited volumes of space-time. He and Arya Vaii, a business student, set out to develop the phenomenon.It quickly becomes obvious that, beyond the fact that time stops inside the stasis field, the volume of space-time in stasis might be useful for some of its other phenomenal properties. Since it essentially can't be altered (time's stopped inside) it's stronger than any known substance and, unlike matter, does not melt. This makes it the perfect material for building rocket engines. They set out to sell such engines in order to provide their budding business enough profit to let them develop other useful products.Unfortunately, the owner of the lab that tested the properties of their samples also recognizes their potential. His desire to share in their profits unhinges his shaky grasp on reality. When he can't talk them into letting him join their enterprise, he demands a share at gunpoint.




The Keeper of the Isis Light


Book Description

Sixteen-year-old Olwen, who lives alone on the planet Isis with her faithful robot, falls tragically in love with an arrival from earth who is unaware that her natural form has been hidden in a humanlike space suit.




Blindsight


Book Description

Hugo and Shirley Jackson award-winning Peter Watts stands on the cutting edge of hard SF with his acclaimed novel, Blindsight Two months since the stars fell... Two months of silence, while a world held its breath. Now some half-derelict space probe, sparking fitfully past Neptune's orbit, hears a whisper from the edge of the solar system: a faint signal sweeping the cosmos like a lighthouse beam. Whatever's out there isn't talking to us. It's talking to some distant star, perhaps. Or perhaps to something closer, something en route. So who do you send to force introductions with unknown and unknowable alien intellect that doesn't wish to be met? You send a linguist with multiple personalities, her brain surgically partitioned into separate, sentient processing cores. You send a biologist so radically interfaced with machinery that he sees x-rays and tastes ultrasound. You send a pacifist warrior in the faint hope she won't be needed. You send a monster to command them all, an extinct hominid predator once called vampire, recalled from the grave with the voodoo of recombinant genetics and the blood of sociopaths. And you send a synthesist—an informational topologist with half his mind gone—as an interface between here and there. Pray they can be trusted with the fate of a world. They may be more alien than the thing they've been sent to find. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.




Radiation Hazard (The Stasis Stories #3)


Book Description

This hard Sci-Fi novel is the third book in the "Stasis Stories," a series of optimistic tales of technological innovation in the near future. They follow Kaem Seba, a sickly and financially destitute young man with extraordinary math talents. With his friends, he's developed a device that allows him to stop time within limited volumes of space-time. In this story, Kaem and company are commercially developing "Stade," which is what they call a piece of space-time that's in stasis. Stade's phenomenal properties (because it essentially can't be altered since time's been stopped within it) allow it to reflect all radiation. When a nearby nuclear reactor undergoes a meltdown, the first thought is that stade might be used to limit the radioactivity from the accident.But a little further thought makes it obvious that stade is also the perfect material for dealing with radioactive waste. They also become interested in using it to remediate a toxic chemical dump.They're still using it to build rocket engines. And working on plans for a space elevator!




Ringworld


Book Description

Winner of the Hugo and Nebula Awards for best novel Four travelers come to the ringworld. . . Louis Wu: human and old; bored with having lived too fully for far too many years. Seeking a challenge, and all too capable of handling it. Nessus: a trembling coward, a puppeteer with a built-in survival pattern of nonviolence. Except that this particular puppeteer is insane. Teela Brown: human; a wide-eyed youngster with no allegiances, no experience, no abilities. And all the luck in the world. Speaker-To-Animals: kzin; large, orange-furred, and carnivorous. And one of the most savage life-forms known in the galaxy. Why did these disparate individuals come together? How could they possibly function together? And where, in the name of anything sane, were they headed?

The Thunder of Engines (a Stasis Story #2)


Book Description

This hard Sci-Fi novel is the second book in the "Stasis Stories," a series of tales from the near future. They tell us about Kaem Seba, a sickly and financially destitute young man with extraordinary math talents. He's developed a theory and an electronic device that allows him to stop time within limited volumes of space-time. In this story Kaem and Arya are trying to sell "stade," which is what they call a piece of space-time that's in stasis. Stade has phenomenal mechanical properties because it essentially can't be altered (time's stopped within it). It's stronger than any known substance because, unlike matter, stade cannot not melt, burn, bend or break. It's also a perfect insulator and reflects all radiation.Though it's the perfect material for thousands of different purposes, they've initially focused on selling it to companies that can use it to build rocket engines. Stade truly shines under the extreme conditions of rocketry, and that renders it precious. He and Arya are struggling to negotiate the best prices they can, while simultaneously fighting another company's bid to preempt their patent.As if those struggles weren't sufficient, Kaem's beloved father develops cancer. Kaem must try to help his family through that crisis while simultaneously attempting to save the new company they're calling "Staze."




To Be Taught, If Fortunate


Book Description

“Extraordinary . . . A future sci-fi masterwork in a new and welcome tradition.” -- Joanne Harris, author of Chocolat A stand-alone science fiction novella from the award-winning, bestselling, critically-acclaimed author of the Wayfarer series. At the turn of the twenty-second century, scientists make a breakthrough in human spaceflight. Through a revolutionary method known as somaforming, astronauts can survive in hostile environments off Earth using synthetic biological supplementations. They can produce antifreeze in subzero temperatures, absorb radiation and convert it for food, and conveniently adjust to the pull of different gravitational forces. With the fragility of the body no longer a limiting factor, human beings are at last able to journey to neighboring exoplanets long known to harbor life. A team of these explorers, Ariadne O’Neill and her three crewmates, are hard at work in a planetary system fifteen light-years from Sol, on a mission to ecologically survey four habitable worlds. But as Ariadne shifts through both form and time, the culture back on Earth has also been transformed. Faced with the possibility of returning to a planet that has forgotten those who have left, Ariadne begins to chronicle the story of the wonders and dangers of her mission, in the hope that someone back home might still be listening.
