To the citizens of the planet Erin, the Godspeed Drive is a legendary device from a lost age before the isolation of the Forty Worlds. To teenager Jay Hara, however, it is his one chance to claim his future in deep space—if he can find it. The author of sets this coming-of-age adventure against the backdrop of a planet struggling in quiet desperation to hold onto the remnants of a dying technology. Despite the high-action content of his plot, Sheffield never slights his characters or his science. A good choice for most sf collections.

Charles Sheffield es uno de esos escritores de ciencia ficción que hace que el resto de nosotros piense seriamente en hacer carrera como vendedores de saldos. De hecho, la única razón por la que le permitimos vivir es que también somos lectores de ciencia ficción. Tiene la base científica de un Clarke, la capacidad narrativa de un Heinlein, la aguda ironía de un Pohl o un Kornbluth y la habilidad como constructor de universos de un Niven.

En el siglo XXII, la combinación de una bio-realimentación potenciada por ordenador con unas nuevas técnicas de quimioterapia ha permitido al ser humano no sólo curarse (eliminando la profesión médica), sino también alterar a voluntad su forma física. La alteración física, sin embargo, presenta aspectos oscuros, y la Agencia de Control de Formas que dirige Behrooz Wolf tiene la misión de impedir que formas ilegales o peligrosas se difundan.

Mientras investiga proyectos de apariencia siniestra, Wolf encuentra pistas que lo conducen al mensaje legado hace millones de años por una especie extraterrestre. Más tarde, la recurrente imagen mental de un misterioso Bailarín le llevará a enfrentarse con los rebeldes que, desde el espacio exterior, se oponen al poder de la Tierra. Razones más que suficientes para replantear lo que significa ser humano precisamente en una época en la cual los humanos adquieren cualquier forma física si lo desean y cuando el nuevo Test de Humanidad resulta esencial para identificar a los miembros de la propia especie.

A estos mundos llegan los inmortales, seres con extraños lazos con la vieja tierra, que parecen vivir eternamente, que pueden recorres años luz en sólo unos días, y que utilizan sus extraños poderes apara controlar la existencia de los simples mortales. En el planeta Pentecostes, un pequeño grupo se prepara para encontrar a los Inmortales y enfrentarse a ellos.

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 a hunch that during this unusal Summertide she might find the Builders themselves. Louis Nenda and the Cecropian Atvar H’sial had their own interests in Quake, and would do anything to get there. And Councilor Julius Graves was hunting murderers — if they were hiding on Quake, he needed no one’s permission to search for them.

Planetary Administrators Hans Rebka and Max Perry had no choice but to go to Quake themselves — risking their lives to protect the others — and to learn, just maybe, the secret of Summertide and the Builders…

Una inteligencia artifical escapa al control de sus creadores y elabora sus propios planes sobre lo que quiere hacer, sin imporrtarle para ello el ser violenta para conseguirlo. Los humanos se unen a un grupo de razas alienígenas para trabajar juntas en la solución del problema, pero tienen muy diferentes ideas sobre cómo abordar el asunto.

Der Gezeitensturm rückt näher: die Zeit, wenn die Zwillingsplaneten Opal und Erdstoß ihrer Sonne am nächsten kommen. Unglaubliche Gezeitenkräfte wirken auf die beiden Welten ein. Diesmal soll es besonders schlimm werden, denn die Große Konjunktion der Sterne und Planeten steht bevor. Über Erdstoß wurde ein absolutes Einreiseverbot verhängt. Doch einige Leichtsinnige lassen sich davon nicht abschrecken. Manche von ihnen sind einer untergegangenen Zivilisation auf der Spur. Andere sind auf Verbrecherjagd. Die Planetenverwalter Hans Rebka und May Perry haben keine Wahl: Sie müssen selbst nach Erdstoß reisen, um die Besucher von der Welt zu schaffen. Sie begeben sich auf eine lebensgefährliche Mission, die ungeahnte Geheimnisse bereithält?

In the 22nd century biofeedback techniques have enabled humans the ultimate expression—the ability to transform the body into any viable form. What began as an innocent technique to reduce anxiety without drugs has raised fundamental questions about what it is to be human. Enter the Humanity Test.

Como Newton en el siglo XVII o Eintein en el XX, McAndrew es el genio indiscutido de la física del siglo XXII. Los , minúsculos agujeros negros cargados y en rotación, no tienen secretos para quien ha descubierto la forma de usarlos como fuente de energía. Su dominio de la ciencia y un sin par sentido práctico le llevan a inventar los más sorprendentes artilugios como la primera nave interestelar sin efectos de inercia. La pilota su compañera, la capitana Jeanie Roker y juntos explorarán a fondo el sistema solar interior, el Halo de cometas que le rodea y llegarán a viajar a Alfa Centauro, en medio de las más sorprendentes situaciones.

Seguir a McAndrew en sus aventuras es adentrarse con gran amenidad en un mundo de brillante especulación y saborear las delicias de la inteligencia.

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.

Solo una minima parte dell’umanità riuscì a sfuggire alla catastrofe nucleare che nel 21° secolo devastò la Terra, rifugiandosi in primitive colonie orbitali attorno al pianeta. Ma una volta vinta la battaglia per la sopravvivenza, cominciò il grande esodo verso nuovi mondi nelle zone più remote dello spazio.

Dopo vari millenni ecco incombere su questi mondi la presenza degli Immortali, esseri che possiedono strani legami con la vecchia Terra, apparentemente in grado di estendere la propria vita all’infinito e di superare distanze di anni luce in pochi giorni. Sul pianeta Pentecoste, alcuni lontanissimi discendenti dell’umanità cercano di scoprire la vera natura degli Immortali, intuendo appena che il contatto con tali creature li porterà ad acquisire conoscenze inimmaginabili, tra cui il segreto dell’S-spazio normale. Ma si tratta solo del principio, perché seguono altre rivelazioni sull’intera storia dell’umanità, dall’origine alla distruzione della Terra e alla secolare diaspora nello spazio, che scatenano nuove inquietudini e rilanciano appassionanti interrogativi. Qual è infatti il segreto dell’enigmatico Punto di Convergenza, una zona lontanissima da ogni stella conosciuta? E fino a dove si estendono i poteri degli Immortali e la loro conoscenza del passato e del futuro dell’umanità? E quali sono, infine, le loro reali intenzioni?

Un epico e illuminante viaggio che interroga il destino dell’uomo nella vastità del cosmo, tra grandiose intuizioni ed ipotesi inedite che esaltano le virtù della miglior fantascienza.

In the aftermath of the “summertide” that nearly destroyed twin planets of Opal and Quake, a few humans and aliens representing various civilized worlds confront the remnants of an ancient technology and discover a threat to life as they know it. Excitement builds rapidly in this fast-paced sequel to . Recommended for large libraries.

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…

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.

18th Century Europe: It is an age when superstition is beginning to give way to the force of human reason, and no man so fully embodies the spirit of the times as Dr. Erasmus Darwin. Thinker, healer, and explorer of the bizarre and the seemingly supernatural, no mystery can stand for long against Darwin’s enlightened analysis. And there are far more mysteries than history knows…

For Erasmus Darwin’s world is filled with oddities that most cannot believe: from unknown beings lurking just outside the boundaries of civilization, to anomalies that even the greatest natural philosophers will be hard-pressed to explain, to mysterious deaths that give rise to fears of malevolent sorcery.

And when the renowned Dr. Darwin is called upon to heal a man dying of an ailment that seems impossible, he has no idea that it is the beginning of a quest that will lead him to the darkest corners of Europe, and a stunning encounter with the most famous inhabitant of a certain Scottish loch…

A few years after the disappearance of the mysterious Builder Artifacts salted throughout the inhabited regions of the universe, a new phenomenon appears in the unexplored Sagittarian Arm of the galaxy, a force with the power to destroy planets. Capt. Hans Rebka and his team of galactic troubleshooters travel to the threatened Marglot system only to find themselves directly in the path of destruction.

En el brazo espiral de la galaxia se han encontrado más de mil doscientos misteriosos y gigantescos artefactos creados por la ignota y ya desaparecida especie de los Constructores. La próxima “Marea Estival” en el sistema planetario formado por los gemelos Sismo y Ópalo, ha de ser el fruto de una Gran Conjunción de estrellas y planetas que sólo sucede cada 350.000 años. Los mejores estudiosos de la tecnología de los Constructores coinciden en suponer que será una oportunidad única para desentrañar el misterio de esos sorprendentes artefactos. Por ello, humanos y alienígenas, con sus rencillas y enfrentamientos, se dan cita en el sistema y se exponen a sus peligros.

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.

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 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 of intelligence, humor, and a pleasing balance of hard science and interesting, engaging characters. Fans will be particularly delighted to renew their acquaintance with Bat, but readers new to Sheffield’s work should take the plunge enthusiastically — this novel easily and gracefully stands alone as a story of people, science, and the puzzles that both can produce.

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 expected, the carnage may be worse than anyone imagined — preliminary data shows that the supernova was no accident, and that the wave of particles may in fact be a beam. Crackerjack hard-SF author Charles Sheffield brings back much of the cast of for this suspenseful, well-paced follow-up, the two most satisfying returnees being sociopath-savant Oliver Guest and his former patient Seth Parsigian. In the book’s subplot, the brilliant Guest and gruff Parsigian must team up to solve a string of grisly child murders on that threatens to push the shield project even further behind schedule.

In the 23rd century, out of all the races of the galaxy, only humanity has discovered the secret of travel between the stars. When a threat to all life arises from non-living cyborgs, suddenly the peculiar human virtues of valor and stubbornness make the despised Earthlings the saviors of all.
