But the greater the magic, the greater the peril—and Lenfell was soon devastated by a war between rival Mageborn factions that polluted land, sea, and air with Wild Magic and unleashed the hideous specters known as Wraithenbeasts.Generations after that terrible war, with the land recovered from crippling wounds and the people no longer threatened by genetic damage, Mageborns still practice their craft—but under strict constraints. Yet so long as the rivalry between the Mage Guardians and the Lords of Malerris continues, the threat of another war is ever-present. And someone has been planning just such a war for many long years, the final strike in a generations-old bid for total power....

    It's a stunning trip through the trenches of a technological war fought with product demos, press releases, and sales pitches.Natch is a master of bio/logics, the programming of the human body. He's clawed and scraped his way to the top of the bio/logics market using little more than his wits. Now his sudden notoriety has brought him to the attention of Margaret Surina, the owner of a mysterious new technology called MultiReal. Only by enlisting Natch's devious mind can Margaret keep MultiReal out of the hands of High Executive Len Borda and his ruthless armies.To fend off the intricate net of enemies closing in around him, Natch and his apprentices must accomplish the impossible. They must understand this strange new technology, run through the product development cycle, and prepare MultiReal for release to the public—all in three days.Meanwhile, hanging over everything is the specter of the infoquake, a lethal burst of energy that's disrupting the bio/logic networks and threatening to send the world crashing back into the Dark Ages.With Infoquake, David Louis Edelman has created a fully detailed world that's both as imaginative as Dune and as real as today's Wall Street Journal.

    Did some cryptic patron race begin the job long ago, then abandon us? Or did we leap all by ourselves? That question burns, yet a greater mystery looms ahead, in the furnace of a star.

    But something of earth, an ancient evil, seemed bent on destroying the Mass.

    Humanity takes to the skies in its millions, with huge resultant problems for governments and police. Virtually all aircraft are grounded, because of the risk of collision with a stray flyer. Airborne delinquents and criminals are practically impossible to control and can be lethal. Robert Hasson is a good policeman. But a near-fatal airborne confrontation with a psychopath has left him shattered, both physically and mentally. Sent to Canada to recuperate (and to escape the attentions of a local businessman whose son he has put away), Hasson is a broken man, unable to face human company, haunted by nightmares and certain that he will never again put on an anti-gravity harness. But his Canadian host, police chief Al Werry, has a major problem on his hands in the shape of a towering unfinished hotel, the Chinook, whose upper levels are inaccessible from the ground, and are used as an illegal meeting place by local gangs of flyers. Worse, the hotel's owner, Buck Morlacher, intends to take the law into his own hands to deal with them. The violence that has been simmering in the town threatens to erupt and Werry seems powerless to stop it. Unwillingly, Hasson finds himself drawn into the conflict and forced to face his own problems. "Vertigo" is vintage Bob Shaw, fast-moving, intelligent and immenselyreadable.

    When the Hunter emerged from his wreck of a ship, he soon realized that a man of earth would make a suitable host. It became obvious, too, that his quarry had already selected his host—but which human being. Then the Hunter found an excellent host in the person of young and intelligent Robert Kinnaird. He made his presence known and, in return for some clever suggestions and help with his search, he helped Robert with his problems. There follows an exciting, excellently wrought, and—you will agree—absolutely unique chase and deduction story. Tense, dramatic, and humorous, too, it's a top-drawer tale of scientific ingenuity. — From the dust jacketOriginally published in Astounding Science Fiction. Also published as From Outer Space, followed by a sequel: Through the Eye of a Needle

    He's many miles from home, half-dead, his left arm is gangrenous, and he possesses--like everyone else--a sense of smell 1000 times better than a wolf's. Ahead of him, in the stinking ruins of New York, hides Carlson, the greatest killer of all time. All Isham has to do is stay alive long enough to find Carlson and kill him. But Carlson is guarded by ghosts. They rode the winds when Earth was bubbling rock, shared the world with men for a million years, and though we sensed their presence we never truly believed in them--for in our arrogance we assumed life was an exclusive property of solids and liquids... Now they've declared war on us, and our species is nearly annihilated...thanks to the man Isham has come to kill.
