. . and an ice cooler containing the head of a freshly killed Stegosaurus. For Leyster and a select group of scientific colleagues an impossible fantasy has come true: the ability to study dinosaurs up close, in their own era and milieu. But tampering with time and paradox can have disastrous effects on the future and the past alike, breeding a violent new strain of fundamentalist terror -- and, worse still, encouraging brilliant rebels like Dr. Gertrude Salley to toy with the working mechanisms of natural law, no matter what the consequences. And when they concern the largest, most savage creatures that ever walked the Earth, the consequences may be too horrifying to imagine . . .

    But before humanity arrived, another species had already claimed Grass for its own. It too had developed a culture...... Now a deadly plague is spreading across the stars, leaving no planet untouched, save for Grass. But the secret of the planet's immunity hides a truth so shattering it could mean the end of life itself.

    Machines soared through the air, churned through the seas, crawled across the surface, pushing ever forward, carrying death. Earth was engaged in titanic struggle. Germany, Russia, France, China, Japan: the maps were changing day by day. The hostilities spread in ever-widening ripples of destruction: Britain, Italy, Africa...The fate of the world hung in the balance. Then the real enemy came. Out of the dark of night, out of the soft glow of dawn, out of the clear blue sky came an invasion force the likes of which Earth had never known - and worldwar was truly joined. The invaders were inhuman and they were unstoppable. Their technology was far beyond our reach, and their goal was simple. Fleetlord Atvar had arrived to claim Earth for the Empire. Never before had Earth's people been more divided. Never had the need for unity been greater. And grudgingly, inexpertly, humanity took up the challenge. In this epic novel of alternate history, Harry Turtledove takes us around the globe. We roll with German panzers; watch the coast of Britain with the RAF; and welcome alien-liberators to the Warsaw ghetto. In tiny planes we skim the vast Russian steppe, and we push the envelope of technology in secret labs at the University of Chicago. Turtledove's saga covers all the Earth, and beyond, as mankind - in all its folly and glory - faces the ultimate threat; and a turning point in history shows us a past that never was and a future that could yet come to be...

    It's the beginning of an incredible odyssey in which John Carter, a gentleman from Virginia and a Civil War veteran, unexpectedly finds himself on to the red planet, scene of continuing combat among rival tribes. Captured by a band of six-limbed, green-skinned savage giants called Tharks, Carter soon is accorded all the honor of a chieftain after it's discovered that his muscles, accustomed to Earth's greater gravity, now give him a decided advantage in strength. And when his captors take as prisoner Dejah Thoris, the lovely human-looking princess of the city of Helium, Carter must call upon every ounce of strength, courage, and ingenuity to rescue her-before Dejah becomes the slave of the depraved Thark leader, Tal Hajus!Excerpt:Her oval face was beautiful in the extreme, her every feature finely chisled and exquisite, her eyes large and lustrous and her head surmounted by a mass of coal black, waving hair, caught loosely into a strange yet becoming coiffure. Similar in face and figure to women of Earth, she was nevertheless a true Martian--and prisoner of the fierce green giants who held me captive, as well!

    Or almost no one. A few people, perhaps one in ten thousand, can still sleep, and they’ve all shared the same mysterious dream. A handful of silent children can still sleep as well, but what they’re dreaming remains a mystery. Global panic ensues. A medical fact: after six days of absolute sleep deprivation, psychosis sets in. After four weeks, the body dies. In the interim, a bizarre new world arises and swallows the old one whole. A world called Nod.

    Even as many on Earth deny their existence, the giant wormlike carnivores prepare the world for the ultimate violation--the enslavement of humanity for food!

    Most of the planet's wild terrain was unexplored...and many of its peoples seclusive and secretive.But for Andrew Carr there was an attraction he could not evade. Darkover drew him, Darkover haunted him--and when his mapping plane crashed in unknown heights, Darkover prepared to destroy him.Until the planet's magic asserted itself--and his destiny began to unfold along lines predicted only by phantoms and wonder workers of the kind Terran science could never acknowledge.THE SPELL SWORD is a Darkover novel to stand with the great ones of the series.

    But mankind is too busy hating, stealing, scheming, and killing to care. As luminous green trails of cosmic dust and vapor stream across the heavens, blood flows beneath: nations wage all-out war, bitter strikes erupt, and jealous lovers plot revenge and murder. The earth slips past the comet by the narrowest of margins, but all succumb to the gases in its tail. When mankind wakes up, everyone is completely and profoundly different. An ill-fated romance between Willie Leadford and Nettie Stuart unfolds in a world buried in misery and bent on its own destruction. After the earth passes through the comet's tail, suffering, pettiness, and injustice melt away. Willie, Nettie, and everyone around them are reborn. They now see themselves and their world in a dramatically new and wonderful way.

    Tracks the progress of a giant black cloud that comes towards Earth and sits in front of the sun, causing widespread panic and death. A select group of scientists and astronomers - including the dignified Astronomer Royal, the pipe smoking Dr Marlowe and the maverick, eccentric Professor Kingsly - engage in a mad race to understand and communicate with the cloud, battling against trigger happy politicians.

    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...

    Ballard's mesmerizing and ferociously prescient novel imagines a terrifying future in which solar radiation and global warming have melted the polar ice caps and Triassic-era jungles have overrun a submerged and tropical London. Set during the year 2145, the novel follows biologist Dr. Robert Kerans and his team of scientists as they confront a surreal cityscape populated by giant iguanas, albino alligators, and endless swarms of malarial insects. Nature has swallowed all but a few remnants of human civilization, and, slowly, Kerans and his companions are transformed—both physically and psychologically—by this prehistoric environment. Echoing Joseph Conrad's Heart of Darkness—complete with a mad white hunter and his hordes of native soldiers—this "powerful and beautifully clear" (Brian Aldiss) work becomes a thrilling adventure and a haunting examination of the effects of environmental collapse on the human mind.
