Mary finds herself far from her family, living in a beautiful castle in the Inn Valley of Tyrol. There she meets Counts, Countesses, the handsome and distant Count Johann Franz, and works hard as a teacher and consultant among the one-percenters of the day. But all is not what it seems in this gilded world, where religion, undercurrents of witchcraft, and vast sums of money create high-stakes contests, and where treachery and death await the unwary or the unprepared.

    But even in a world of prosperity and freedom there were malcontents. They called themselves Overlord, and their possession of time travel gave them the ability to change the past and shape the future according to their twisted desires. They built a time gate, then picked a crucial turning point in the previous century and traveled back to transmute an obscure figure on the lunatic fringe of German politics into an invincible conqueror. His name: Adolph Hitler. By the 1970s, only North America and Australia remained free, but time was running out and both would soon be faced with a choice of surrender or nuclear annihilation.

    After convincing General Groves of his new method, Cohen and his team of scientists work at Oak Ridge preparing to have a nuclear bomb ready to drop by the summer of 1944 in an effort to stop the war on the western front. What ensues is an altered account of World War II in this taut thriller. Combining fascinating science with intimate and true accounts of several members of The Manhattan Project, The Berlin Project is an astounding novel that reimagines history and what could have happened if the atom bomb was ready in time to stop Hitler from killing millions of people.

    See, my name is Karen Memery, like memory only spelt with an e, and I'm one of the girls what works in the Hôtel Mon Cherie on Amity Street. Hôtel has a little hat over the o like that. It's French, so Beatrice tells me."Set in the late 19th century—when the city we now call Seattle Underground was the whole town (and still on the surface), when airships plied the trade routes, would-be gold miners were heading to the gold fields of Alaska, and steam-powered mechanicals stalked the waterfront, Karen is a young woman on her own, is making the best of her orphaned state by working in Madame Damnable's high-quality bordello. Through Karen's eyes we get to know the other girls in the house—a resourceful group—and the poor and the powerful of the town. Trouble erupts one night when a badly injured girl arrives at their door, begging sanctuary, followed by the man who holds her indenture, and who has a machine that can take over anyone's mind and control their actions. And as if that wasn't bad enough, the next night brings a body dumped in their rubbish heap—a streetwalker who has been brutally murdered.Bear brings alive this Jack-the-Ripper yarn of the old west with a light touch in Karen's own memorable voice, and a mesmerizing evocation of classic steam-powered science.

    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.

    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.

    Tom, a contemporary historian, and his theoretical physicist girlfriend Sharon, become interested. Tom indeed becomes obsessed. By all logic, the town should have survived, but it didn't and that violates everything Tom knows about history. What's was special about Eifelheim that it utterly disappeared more than 600 years ago? Father Dietrich is the village priest of Oberhochwald, the village that will soon gain the name of Teufelheim, in later years corrupted to Eifelheim, in the year 1348, when the Black Death is gathering strength across Europe but is still not nearby. Dietrich is an educated man, knows science and philosophy, and to his astonishment becomes the first contact between humanity and an alien race from a distant star when their interstellar ship crashes in the nearby forest. It is a time of wonders, in the shadow of the plague.Tom and Sharon, and Father Dietrich, have a strange and intertwined destiny of tragedy and triumph in this brilliant SF novel by the winner of the Robert A. Heinlein Award.

    That single tragedy set off a whole series of events, resulting in the Spanish Armada's defeat of England and subsequent demise of Protestantism. Now it's the 20th century, and the Church of Rome reigns supreme. People live a pastoral existence of guilds and farming, with technology held back to the level of the steam locomotive and primitive radio. Still, science cannot be held back forever...a revolution is building.

    Michael Davies is prepping to go to Pearl Harbor. Merope Ward is coping with a bunch of bratty 1940 evacuees and trying to talk her thesis adviser into letting her go to VE-Day. Polly Churchill’s next assignment will be as a shopgirl in the middle of London’s Blitz. But now the time-travel lab is suddenly canceling assignments and switching around everyone’s schedules. And when Michael, Merope, and Polly finally get to World War II, things just get worse. For there they face air raids, blackouts, and dive-bombing Stukas--to say nothing of a growing feeling that not only their assignments but the war and history itself are spiraling out of control. Because suddenly the once-reliable mechanisms of time travel are showing significant glitches, and our heroes are beginning to question their most firmly held belief: that no historian can possibly change the past.

    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
