The young man from a shadowy government entity approaches Mel, a low-level faculty member, with an incredible offer. The only condition: she must sign a nondisclosure agreement in return for the rather large sum of money.Tristan needs Mel to translate some very old documents, which, if authentic, are earth-shattering. They prove that magic actually existed and was practiced for centuries. But the arrival of the scientific revolution and the Age of Enlightenment weakened its power and endangered its practitioners. Magic stopped working altogether in 1851, at the time of the Great Exhibition at London’s Crystal Palace—the world’s fair celebrating the rise of industrial technology and commerce. Something about the modern world "jams" the "frequencies" used by magic, and it’s up to Tristan to find out why.And so the Department of Diachronic Operations—D.O.D.O. —gets cracking on its real mission: to develop a device that can bring magic back, and send Diachronic Operatives back in time to keep it alive . . . and meddle with a little history at the same time. But while Tristan and his expanding operation master the science and build the technology, they overlook the mercurial—and treacherous—nature of the human heart.Written with the genius, complexity, and innovation that characterize all of Neal Stephenson’s work and steeped with the down-to-earth warmth and humor of Nicole Galland’s storytelling style, this exciting and vividly realized work of science fiction will make you believe in the impossible, and take you to places—and times—beyond imagining.

    When HMS Reliant captures a French frigate and seizes the precious cargo, an unhatched dragon egg, fate sweeps Captain Will Laurence from his seafaring life into an uncertain future – and an unexpected kinship with a most extraordinary creature. Thrust into the rarified world of the Aerial Corps as master of the dragon Temeraire, he will face a crash course in the daring tactics of airborne battle. For as France’s own dragon-borne forces rally to breach British soil in Bonaparte’s boldest gambit, Laurence and Temeraire must soar into their own baptism of fire.

    His skills of deduction are legendary, and her own sorcery is not inconsiderable. It doesn't help much that they barely tolerate each other, or that Bannon's Shield, Mikal, might just be a traitor himself. Or that the conspiracy killing registered mentaths and sorcerers alike will just as likely kill them as seduce them into treachery toward their Queen. In an alternate London where illogical magic has turned the Industrial Revolution on its head, Bannon and Clare now face hostility, treason, cannon fire, black sorcery, and the problem of reliably finding hansom cabs. The game is afoot..

    However, when rocks shake off their ancient dust and begin to roll—seemingly of their own volition—carving canals as they converge to form a towering structure amid the ruddy terrain, Lt. Jain and her JSC team realize that their routine geological survey of a Martian cave system is anything but. The only clues they have stem from the emissions of a mysterious blue radiation, and a 300-year-old journal that is writing itself.Lt. Thomas Weatherby of His Majesty’s Royal Navy is an honest 18th-century man of modest beginnings, doing his part for King and Country aboard the HMS Daedalus, a frigate sailing the high seas between continents…and the immense Void between the Known Worlds.With the aid of his fierce captain, a drug-addled alchemist, and a servant girl with a remarkable past, Weatherby must track a great and powerful mystic, who has embarked upon a sinister quest to upset the balance of the planets—the consequences of which may reach far beyond the Solar System, threatening the very fabric of space itself.

    history where the British control with magic and the colonists rebel by inventing.It’s 1888, and sixteen-year-old Verity Newton lands a job in New York as a governess to a wealthy leading family—but she quickly learns that the family has big secrets. Magisters have always ruled the colonies, but now an underground society of mechanics and engineers are developing non-magical sources of power via steam engines that they hope will help them gain freedom from British rule. The family Verity works for is magister—but it seems like the children's young guardian uncle is sympathetic to the rebel cause. As Verity falls for a charming rebel inventor and agrees to become a spy, she also becomes more and more enmeshed in the magister family’s life. She soon realizes she’s uniquely positioned to advance the cause—but to do so, she’ll have to reveal her own dangerous secret.

    or had not occurred at all? In this stellar collection, twelve of science fiction's most imaginative minds have altered the past to reveal a present of astonishing and startling possibilities...a rare glimpse of what might have been. From a Germany that won the war to a modern exodus from Egypt, from the death of ancient Greece to the true secret of the Soviets, these hold excursions in time depict bizarre new worlds -- oddly familiar, disturbingly different.Summary:Poul Anderson's "In the House of Sorrows" Gregory Benford's "We Could Do Worse"George Alec Effinger's "Everything but Honor"Karen Joy Fowler's "Game Night at the Fox and Goose"Barry N.

    Only three things stand between the Malwa and the conquest of Earth: Byzantium, the empire of Rome in the East; a crystal that urges mankind to fight; and Belisarius, general of the Byzantine Empire, and arguably the greatest commmander the Earth has ever known.

     Future America is dangerous and bankrupt. The interstate highways are littered with the rusted hulks of ambushed cars and trucks, and only Mad Max would dare travel the back roads. When an arms race with Russia and China to develop time travel for military purposes achieves success, the body count skyrockets as both patriot and enemy try to hijack the new technology. Like the Manhattan Project and Operation Overtime before it, such a project attracts the best and the brightest as well as the worst and the psychotic. But not everyone has given up on the rule of law. In Tennessee, Fayette County D.A. Pete Dance wants to prosecute the murder of a man whose fossilized remains turn up after a series of devastating earthquakes. The problem is that the victim is still alive. When the violence starts, it doesn’t stop until the final whirlwind of teeth and claws and lasers. The first spinoff series from William Alan Webb’s immensely popular series The Last Brigade is described by one critic as “…Spectre agents chasing Fast and Furious through Jurassic World,” while another reviewer added “…with a heavy dose of Harry Bosch for good measure.” “After the heart-pounding finale, you won’t see the shocking ending coming. Guaranteed to keep you awake at night.”

    The Allies are wildly out maneuvered and sent home in disgrace. Back in the States things are looking rather grim as the ultra-secret Manhattan Project runs into snafus that greatly delay the final production of the atomic bomb. President Roosevelt's approval ratings drop dramatically. Congress is desperate and the country cries out for a hero. That hero might just be Douglas MacArthur, who vowed that he would return to his beloved Philippines. He plans to do so with the backing of the entire US Armed Forces.MacArthur's plan of action is simple: take the war back to the Japanese, island by bloody island, until standing on the shores of Japan, he can proclaim victory. And possibly gain the leadership of the United States as well.

    The Separation suggests an alternate history lying along a road not taken in World War II. But there are complications. In 1999, history author Stuart Gratton is intrigued by a minor mystery of the European war which ended on 10 May 1941. The British-German armistice signed that month has had far-reaching consequences, including a resettlement of European Jews in Madagascar. In 1936, the identical twin brothers Joe and Jack Sawyer win a rowing medal for Britain in the Berlin Olympics: it's presented to them by Rudolf Hess. The brothers are separated not only by a twin's fierce need "to be treated as a separate human being", but by sexual rivalry and even ideology. When war breaks out Jack becomes a gung-ho bomber pilot, Joe a conscientious objector. Still they're inescapably linked, and sometimes confused. Both suffer injuries and hauntingly similar ambulance journeys. Churchill writes a puzzled memo (later unearthed by Gratton) about the anomaly of a registered-pacifist Red Cross worker flying planes for Bomber Command. Hess has significant, eventually incompatible meetings with both men. Contradictions are everywhere. As in his magical 1995 novel The Prestige Priest is fruitfully fascinated by the legerdemain of twins, doubles, impostors, symmetrical roles. Churchill's double briefly appears. So does the famous conspiracy theory that the Hess who flew to Britain with his quixotic peace deal wasn't the real Hess ring true? Clearly The Separation was impressively, extensively researched. Its evocations of bombing raids--from either side of the bomb sites--are memorable. The unfolding story strands become increasingly disorienting and hallucinatory; the easy escape route of dismissing one strand as delusion is itself subtly undermined. The Separation is filled with a sense of the precariousness of history; of small events and choices with extraordinary consequences. --David Langford

    With the Nazis recently defeated, Stalin gathers half a dozen of the top Soviet science fiction authors in a dacha in the countryside. Convinced that the defeat of America is only a few years away—and equally convinced that the Soviet Union needs a massive external threat to hold it together—Stalin orders the writers to compose a massively detailed and highly believable story about an alien race poised to invade the earth. The little group of writers gets down to the task and spends months working until new orders come from Moscow to immediately halt the project. The scientists obey and live their lives until, in the aftermath of Chernobyl, the survivors gather again, because something strange has happened: the story they invented in 1946 is starting to come true.
