Sarah Halifax decoded the first-ever radio transmission received from aliens. Thirty-eight years later, a second message is received and Sarah, now 87, may hold the key to deciphering this one, too... if she lives long enough. A wealthy industrialist offers to pay for Sarah to have a rollback—a hugely expensive experimental rejuvenation procedure. She accepts on condition that Don, her husband of sixty years, gets a rollback, too. The process works for Don, making him physically twenty-five again. But in a tragic twist, the rollback fails for Sarah, leaving her in her eighties. While Don tries to deal with his newfound youth and the suddenly vast age gap between him and his wife, Sarah struggles to do again what she’d done once before: figure out what a signal from the stars contains.

    Each sought his own brand of happiness. But none could have guessed what awaited them. Not even in a million years....

    They can't contact the aliens in any way or understand their language. All they can do is watch.Then, without warning, a military cordon is imposed on the Blind Lake site. All communication with the outside world is cut off. Food and other vital supplies are delivered by remote control. No one knows why.The scientists, nevertheless, go on with their research. Among them are Nerissa Iverson and the man she recently divorced, Raymond Scutter. They continue to work together despite the difficult conditions and the bitterness between them. Ray believes their efforts are doomed; that culture is arbitrary, and the aliens will forever be an enigma.Nerissa believes there is a commonality of sentient thought, and that our failure to understand is our own ignorance, not a fact of nature. The behavior of the alien she has been tracking seems to be developing an elusive narrative logic--and she comes to feel that the alien is somehow, impossibly, aware of the project's observers.But her time is running out. Ray is turning hostile, stalking her. The military cordon is tightening. Understanding had better come soon...

But Leisha and a few others remain behind, preaching acceptance for all humans, Sleepless and Sleeper alike. With the conspiracy and revenge that unwinds, the world needs a little preaching on tolerance.

    McHugh established herself as one of the decade's best science fiction writers. In its pages, we enter a post-revolution America, moving from the hyper-urbanized eastern seaboard to the Arctic bleakness of Baffin Island; from the new Imperial City to an agricultural commune on Mars. The overlapping lives of cyber-kite fliers, lonely colonists, illicit neural-pressball players, and organic engineers blend into a powerful, taut story of a young man's journey of discovery. This is a macroscopic world of microscopic intensity, one of the most brilliant visions of modern SF.

    Rails must be freshly laid ahead of the city & carefully removed in its wake. Rivers & mountains present nearly insurmountable challenges to the ingenuity of the city's engineers. But if the city does not move, it will fall farther & farther behind the optimum & into the crushing gravitational field that has transformed life on Earth. The only alternative to progress is death. The secret directorate that governs the city makes sure that its inhabitants know nothing of this. Raised in common in creches, nurtured on synthetic food, prevented above all from venturing outside the closed circuit of the city, they're carefully sheltered from the dire necessities that have come to define human existence. Yet the city is in crisis. People are growing restive. The population is dwindling. The rulers know that, for all their efforts, slowly but surely the city is slipping ever farther behind the optimum. Helward Mann is a member of the city's elite. Better than anyone, he knows how tenuous is the city's continued existence. But the world he's about to discover is infinitely stranger than the strange world he believes he knows so well.

    But the journey has a terrible cost. It alters not only the future but the "present" in which we live.A century after the publication of H. G. Wells' immortal The Time Machine, Stephen Baxter, today's most acclaimed new "hard SF" author, and the acknowledged Clarke, returns to the distant conflict between the Eloi and the Morlocks in a story that is at once an exciting expansion, and a radical departure based on the astonishing new understandings of quantum physics.

    A constant stream of new technology spawns crime before it hits the streets; the human mind and the external landscape have fused to the point where any encounter with "reality" is incidental.

    A stunning collection of the kind of fiction that has only one source--the unparalleled Ray Bradbury.

    He's lived long enough to see the cure for death and the end of scarcity, to learn ten languages and compose three symphonies...and to realize his boyhood dream of taking up residence in Disney World.Disney World! The greatest artistic achievement of the long-ago twentieth century. Now in the keeping of a network of "ad-hocs" who keep the classic attractions running as they always have, enhanced with only the smallest high-tech touches.Now, though, the "ad hocs" are under attack. A new group has taken over the Hall of the Presidents, and is replacing its venerable audioanimatronics with new, immersive direct-to-brain interfaces that give guests the illusion of being Washington, Lincoln, and all the others. For Jules, this is an attack on the artistic purity of Disney World itself. Worse: it appears this new group has had Jules killed. This upsets him. (It's only his fourth death and revival, after all.) Now it's war....
