In the mid-1870s, a violent spray of comets hits Earth, decimating cities, erasing shorelines, and changing the world's climate forever. And just as Earth's temperature dropped, so was civilization frozen in time. Instead of advancing technologically, humanity had to piece itself back together.... In the 21st century, boats still run on steam, messages arrive by telegraph, and the British Empire, with its capital now in Delhi, controls much of the world.

Marc Vitrac was born in the early 1960's, about the time the first interplanetary probes delivered the news that Mars and Venus were teeming with life, even human life.

But there are flies in this ointment - and not only the Venusian dragonflies, with their yard-wide wings....Extravagant and effervescent, The Sky People is alternate-history SF adventure at its best.

They discover groups of the similarly displaced: imperial Romans, Neolithic Europeans, and a small cadre of East Indian peasants.

War seethed across the planet. Machines soared through the air, churned through the seas, crawled across the surface, pushing ever forward, carrying death. Earth was engaged in titanic struggle. Germany, Russia, France, China, Japan: the maps were changing day by day. The hostilities spread in ever-widening ripples of destruction: Britain, Italy, Africa...the fate of the world hung in the balance. Then the real enemy came.

Boarding a transport ship after the Battle of Gettysburg, Colonel Andrew Keane and his 35th Maine regiment are swept into an alternate world. The first human civilization they encounter on this planet resembles medieval Russia, with boyars and priests ruling over the peasants and townspeople.

When an experiment to study quantum uncertainty goes spectacularly wrong, physics student Bill Rustad and his friends find that they have accidentally created an inter-dimensional portal. They connect to Outland - an alternate Earth with identical geology, but where humans never evolved. The group races to establish control of the portal before the government, the military, or evildoers can take it away. Then everything changes when the Yellowstone supervolcano erupts in an explosion large enough to destroy civilization and kill half the planet.

Joe Colsco boarded a flight from San Francisco to Chicago to attend a national chemistry meeting. He would never set foot on Earth again.

He awakes amid strangers speaking an unintelligible language and struggles to accept losing his previous life and finding a place in a society with different customs, needing a way to support himself and not knowing a single soul.

Humanity pushed its way to the stars—and encountered the Gbaba, a ruthless alien race that nearly wiped us out. Earth and her colonies are now smoldering ruins, and the few survivors have fled to distant, Earth-like Safehold, to try to rebuild. But the Gbaba can detect the emissions of an industrial civilization, so the human rulers of Safehold have taken extraordinary measures: with mind control and hidden high technology, they've built a religion in which every Safeholdian believes, a religion designed to keep Safehold society medieval forever.

History is rewritten in an instant as the future smashes into the past, and high-tech hardware goes head to head with World War Two technology. In the chaos that ensues, thousands are killed, but the maelstrom has only just begun. The veterans of Pearl Harbor have never seen a helicopter, or a cruise missile - let alone nanotechnology, ceramic bullets, and F22 Raptor stealth jetfighters.

Everyone could see it coming. But one man could do something about it. Oh, he couldn't avert the nuclear holocaust, but a scientist in Austria, ruthlessly using billions of research dollars for his own purposes, set himself up and out: he created a time machine, and filled a warehouse with low-tech survival gear. Too bad he didn't get to use it himself. Instead, a team of American grad students, led by their professor, is sent back to the late Roman Empire. Even though they are experts in this time and place, they are about to realize that books and actual experience are very different things.

When the convulsions subside, the crew and passengers of the ship discover that they have arrived in a new and frightening world. They are in the Mediterranean now, not the Caribbean.

In this alternate history of the American frontier and the Jacksonian era, a small change takes place in the Battle of the Horseshoe Bend during the War of 1812. What results is a cascade of new developments that becomes an avalanche. In our world, Ensign Sam Houston, just turned 21, led the charge on the creek barricade in that battle and almost died from a terrible wound that took him a year to recover from. In this world, his wound is minor, so he is able to continue fighting the British—and develop his close relationship with Andrew Jackson much sooner.
