    For aeons this golden-skinned, golden-eyed race had provided the universe mercenary soldiers of almost unimaginable ability. But now the mri have faced an enemy unlike any other - an enemy whose only way of war is widespread destruction. These "humans" are mass fighters, creatures of the herd, and the mri have been slaughtered like animals.Now, in the aftermath of war, the mri face extinction. It will be up to three individuals to save whatever remains of this devastated race: a warrior - one of the last survivors of his kind; a priestess of this honorable people; and a lone human - a man sworn to aid the enemy of his own kind. Can they retrace the galaxy-wide path of this nomadic race back through millennia to reclaim the ancient world which first gave them life?

    Nine misfit academics on an expedition to find the volcryn, a mythic race of intersteller nomads, and the only ship available for this strange quest is the Nightflyer, a cybernetic wonder with a never-seen captain...Nine innocents are about to find themselves in deep space, trapped with an insane murderer who can go anywhere, do anything, and intends to kill them all.

    It is the monumental story of a Galactic Empire in decline, and the secret society of scientists who seek to shorten the inevitable Dark Age with the science of psychohistory. Now, with the permission -- and blessing -- of the Asimov estate, the epic saga continues.Fate -- and a cruel Emperor's arbitrary power -- have thrust Hari Seldon into the First Ministership of the Empire against his will. As the story opens, Hari is about to leave his quiet professorship and take on the all but impossible task of administering 25 million inhabited worlds from the all-steel planet of Trantor. With the help of his beautiful bio-engineered "wife" Dors and his alien companion Yugo, Seldon is still developing the science that will transform history, never dreaming that it will ultimately pit him against future history's most awesome threat.

    This volume, The Weapon Shops of Isher, includes the first three parts of the saga and introduces perhaps the most famous political slogan of science fiction: The Right to Buy Weapons is the Right to Be Free. Born at the height of Nazi conquest, the Isher stories suggested that an oppressive government could never completely subjugate its own citizens if they were well armed. The audience appeal was immediate and has endured long beyond other stories of alien invasion, global conflict and post war nuclear angst.

    But if that is the case, what is his real world like, and what is he actually doing every day when he thinks he is guessing 'Where Will The Little Green Man Be Next?'

    Now the abscess was about to burst. Captain Harris had left the controls on autopilot and was talking to the front row of passengers as the first tremor shook the boat. For a fraction of a second he wondered if a fan blade had hit some submerged obstacle; then, quite literally, the bottom fell out of his world.It fell slowly, as all things must upon the Moon. The sea was alive and moving . . . Every stage of that nightmare transformation was pitilessly illuminated by the earth light, until the crater was so deep that its firewall was completely lost in shadow, and it seemed as if Selene were racing into a curving crescent of utter blackness – an arc of annihilation.In darkness and in silence, they were sinking into the Moon. . . .

    There was no credit card, birth record, or passport for him in the International Data Bank. His names were many...any he chose. His occupation was taking megarisks in the service of a vast global detective agency. His interworld assignments were highly lucrative, incalculably vital, and terrifyingly deadly. And more often then not, his life was a living hell!Contents:1 · The Eve of RUMOKO · na Three for Tomorrow, ed.

    When they reach the planet Grudgrodd, they come across another space-faring species. It's a case of instant dislike. The gentle Utods do not feel pain, they change sex as the planet changes suns, they live long pleasurable lives, free of stress. They wallow in their own middens. But 'Civilisation is the distance man has placed between himself and his excreta'. So the carnage begins.

    But hours after his arrival he witnesses a murder and is forced into hiding.It is also the first visit for celebrity travel reporter Ta Shu. He has contacts and influence, but he too will find that the moon can be a perilous place for any traveler.Finally, there is Chan Qi. She is the daughter of the Minister of Finance, and without doubt a person of interest to those in power. She is on the moon for reasons of her own, but when she attempts to return to China, in secret, the events that unfold will change everything - on the moon, and on Earth.

    Foul play by the Soviets is suspected, and the world draws close to nuclear war. But the answer has nothing to do with human deeds.

    Hellstrom's Project 40 was a cover for a secret laboratory, a special team of agents was immediately dispatched to discover its true purpose and its weaknesses—it could not be allowed to continue. What they discovered was a nightmare more horrific and hideous than even their paranoid government minds could devise.First published in Galaxy magazine in 1973 as "Project 40," Frank Herbert's vivid imagination and brilliant view of nature and ecology have never been more evident than in this classic of science fiction.

    As scientists frantically work to prevent the ultimate disaster, they discover that the entire planet could be destroyed within a year. But while they look for an answer, some claim that the only way to save Earth is to let its human inhabitants become extinct: to reset the evolutionary clock and start over.

    The planet attracted unwary travelers, hardened space-sailors, and merchant buccaneers -- a teeming, constantly shifting horde that provided a comfortable income for certain quick-witted fellows like Flinx and his pet flying snake Pip. With his odd talents, the pickings were easy enough so that Flinx did not have to be dishonest ... most of the time.In fact, it hardly seemed dishonest at all to steal a starmap from a dead body that didn't really need it anymore. But Flinx wasn't quite smart enough. He should have wondered why the body was dead in the first place...
