It was a simple mission. A standard crew.THE PROBLEMKai and his beautiful co-leader Varian, the best xenob-vet in the business, followed all the standard procedures -- but the results of their investigations were totally unexpected. Not only were the planet's creatures larger than anyone had anticipated and the geological finds smaller, but the rescue ship had inexplicably disappeared.THE NIGHTMAREThen suddenly on a world of giant swamp creatures and deadly predators, a curious change had come over many of the members of the ARCT-10 crew... a change that would lead all of them, in one way or another, into the primitive darkness of a future world.

    On an island with a glass shore - relic of some even more ancient conflict - she discovers she is to be hunted by the Huhsz, a religious cult which believes she is the last obstacle before their faith's apotheosis. She has to run, knowing her only hope of finally escaping the Huhsz is to find the last of the ancient, apocalyptically powerful but seemingly cursed Lazy Guns. But that is just the first as well as the final step on a search that takes her on an odyssey through the exotic Golterian system and results in both a trail of destruction and a journey into her own past, as well as that of her family and the system itself; a journey that changes everything.

    Donaldson returns with this exciting and long-awaited new series that takes us into a stunningly imagined future to tell a timeless story of adventure and the implacable conflict of good and evil within each of us.Angus Thermopyle was an ore pirate and a murderer; even the most disreputable asteroid pilots of Delta Sector stayed locked out of his way.  Those who didn't ended up in the lockup--or dead.  But when Thermopyle arrived at Mallory's Bar & Sleep with a gorgeous woman by his side the regulars had to take notice.  Her name was Morn Hyland, and she had been a police officer--until she met up with Thermopyle.But one person in Mallory's Bar wasn't intimidated.  Nick Succorso had his own reputation as a bold pirate and he had a sleek frigate fitted for deep space.  Everyone knew that Thermopyle and Succorso were on a collision course.  What nobody expected was how quickly it would be over--or how devastating victory would be.  It was common enough example of rivalry and revenge--or so everyone thought.  The REAL story was something entirely different.In The Real Story, Stephen R. Donaldson takes us to a remarkably detailed world of faster-than-light travel, politics, betrayal, and a shadowy presence just outside our view to tell the fiercest, most profound story he has ever written.

    His mission: save, develop, and protect the group of Pak breeders sent out into space some two and a half million years before...Brennan was a Belter, the product of a fiercely independent, somewhat anarchic society living in, on, and around an outer asteroid belt. The Belters were rebels, one and all, and Brennan was a smuggler. The Belt worlds had been tracking the Pak ship for days -- Brennan figured to meet that ship first...He was never seen again -- at least not by those alive at the time.

    Titan, an independent republic, was originally colonized from Earth three generations earlier. Duncan's initial challenge is to prepare, physically and intellectually, for the 500-million-mile trip to Earth. Once there, he is caught up in a sweep of new experiences, including the social and political whirl in Washington, a strange visit to a carefully preserved ancient city once prominent in the 20th century, and a search for and meeting with a woman he loved since she visited Titan years before.

    More than a century of ecological damage, industrial and technological expansion, and unchecked population growth has left the Earth on the brink of devastation. As the world’s governments turn inward, one man dares to envision a bolder, brighter future. That man, Reid Malenfant, has a very different solution to the problems plaguing the planet: the exploration and colonization of space. Now Malenfant gambles the very existence of time on a single desperate throw of the dice. Battling national sabotage and international outcry, as apocalyptic riots sweep the globe, he builds a spacecraft and launches it into deep space. The odds are a trillion to one against him. Or are they?

    But when an alien spacecraft crash-lands in the South Pacific bearing visitors from another world, the Vulcans, Earth must decide whether to extend the hand of friendship, or the fist of war. In the distant future, horrible dreams torment Admiral James T. Kirk, dreams prompted by his reading of Strangers from the Sky, a book about that historic first contact. He dreams of an alternate reality where he somehow changed the course of history, and destroyed the Federation before it began.

    Humanity’s greatest dreams have become reality. Along with dozens of other sentient races, the people of Earth have formed the United Federation of Planets—a galactic civilization that governs much of the known universe for the good of all. Over the past two centuries, mankind has tamed its basest instincts, and reached the stars…But suppose it hadn’t happened that way at all? Suppose instead humanity’s darkest impulses, its most savage, animalistic desires had triumphed? Suppose that the empire mankind made out in the stars was one ruled by terror, where only those willing to brutalize their own kind and their neighbors could survive?One hundred years ago, four crewmembers of the U.S.S. Enterprise crossed the dimensional barrier and found just such an empire. A mirror image of their own universe, populated by nightmare duplicates of their shipmates. Barely able to escape with their lives, they returned thankful that the accident that brought them there could not be duplicated. Or so they thought.But now the scientists of that empire have found a doorway into our universe. Thier plan: to destroy from within, to replace one of our starships with one of theirs. Their victims: the crew of the U.S.S. Enterprise NCC 1701-D.

    Dennis Nuel is a physicist who, during his research, develops a machine that allows him to explore alternate realities, each of which sport some very strange scientific properties.

    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.

    Then came the announcement that the whole thing was a hoax. End of story. Case closed.Except that two agents of the most secret intelligence agency in the U.S. government were on the scene and disappeared without reporting back. Then four more follow up agents also disappeared. So the head of the agency and his two top agents went in and managed to get out with their discovery: an invasion is underway by slug-like aliens who can touch a human and completely control his or her mind. What the humans know, they know. What the slugs want, no matter what, the human will do. And most of Iowa is already under their control.Sam Cavanaugh was one of the agents who discovered the truth. Unfortunately, that was just before he was taken over by one of the aliens and began working for the invaders, with no will of his own. And he has just learned that a high official in the Treasury Department is now under control of the aliens. Since the Treasury Department includes the Secret Service, which safeguards the President of the United States, control of the entire nation is near at hand.

    Whether it wanted to or not. When the Amplitur and their allies stumbled upon the races called the Weave, the Purpose seemed poised for a great leap forward. But the Weave's surprising unity also gave it the ability to fight the Amplitur and their cause. And fight it did, for thousands of years.Will Dulac was a New Orleans composer who thought the tiny reef off Belize would be the perfect spot to drop anchor and finish his latest symphony in solitude. What he found instead was a group of alien visitors, a scouting party for the Weave, looking for allies among what they believed to be a uniquely warlike race, Humans.Will tried to convince the aliens that Man was fundamentally peaceful, for he understood that Human involvement would destroy the race. But all too soon, it didn't matter. The Amplitur had discovered Earth...
