During a perfect spring evening on Nantucket, a violent storm erupts and a dome of crawling, colored fire blankets the island. When the howling winds subside and the night skies clear, the stars appear to have shifted. The mainland has become a wilderness of unbroken forest, where tools of bronze and stone litter the beaches, and primitive natives scatter in terror.

Michael Havel was flying over Idaho en route to the holiday home of his passengers when the plane's engines inexplicably died, forcing a less than perfect landing in the wilderness. And, as Michael leads his charges to safety, he begins to realize that the engine failure was not an isolated incident.

Pressed into service when World War II breaks out in the Pacific, the USS Walker---a Great-War vintage "four-stacker" destroyer---finds itself in full retreat from pursuit by Japanese battleships. Its captain, Lieutenant Commander Matthew Patrick Reddy, knows that he and his crew are in dire straits. In desperation, he heads Walker into a squall, hoping it will give them cover---and emerges somewhere else.

Defeated, crushed, and driven almost to extinction, the remnants of the human race is trapped on a planet that is constantly attacked by mysterious alien starfighters. Spensa, a teenage girl living among them, longs to be a pilot. When she discovers the wreckage of an ancient ship, she realizes this dream might be possible - assuming she can repair the ship, navigate flight school, and (perhaps most importantly) persuade the strange machine to help her. Because this ship, uniquely, appears to have a soul.

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.

The impossible has spawned the unthinkable. In 2021, a quantum military experiment goes horrifically wrong. A multinational taskforce of ultramodern warships is suddenly transported back in time to 1942...right into the path of the US naval battle group bound for Midway Atoll. 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.

For Lt. Commander Colin Maclntyre, it began as a routine training flight over the moon. For Dahak, a self-aware Imperial battleship, it began millennia ago when that powerful artificial intelligence underwent a mutiny in the face of the enemy. The mutiny was never resolved - Dahak was forced to maroon not just the mutineers but the entire crew on prehistoric Earth.  

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.

 In 1912, just months before the election, President Taft dies suddenly, and Teddy Roosevelt wastes no time in grabbing power as he wins another term as president. By force of will, he ushers the United States into a new, progressive era with the help of the Black Chamber, the mysterious spy organization watching his back.  

Joe Colsco boarded a flight from San Francisco to Chicago to attend a national chemistry meeting. He would never set foot on Earth again. On planet Anyar, Joe is found unconscious on a beach of a large island inhabited by humans where the level of technology is similar to Earth circa 1700. 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.
