After the Nuclear Spasm in the 21st century, Homo sapiens 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.

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 Cold as Ice 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.Spider Robinson

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.Внимание!

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 His Brother’s Keeper.The book was written in 1982 and revised in 1998.

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…

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…

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.

In The Billion Dollar Boy, rich, spoiled, overweight 15-year-old Shelby Cheever is bored, so he convinces his mother to take him on a space cruise. Without proper preparation, and drunk besides, he accesses the node network alone to visit the Kuiper asteroid belt and finds himself hurtled 27 light years out to the Messina Dust Cloud, where he is rescued by a mining family.

In the hard-science Tomorrow & Tomorrow, Sheffield explores changes in the solar system and the theory of a closed vs. open system wrapped around a tale of a musician’s fanatical love for his wife. Drake Merlin has his dying wife Ana and himself cryonically frozen so they can be together once a cure for her disease is found. Several times over 15 billion years he is awakened only to find no cure and, one time, he accidentally causes Ana’s death. But if the theory of a closed system is true and the universe shrinks, he and Ana can return to a point when she is alive.
