Suddenly the planet and every living thing on it no longer exist in a single timeline. Instead, the world becomes a patchwork of eras, from prehistory to 2037, each with its own indigenous inhabitants.Scattered across the planet are floating silver orbs impervious to all weapons and impossible to communicate with. Are these technologically advanced devices responsible for creating and sustaining the rifts in time? Are they cameras through which inscrutable alien eyes are watching? Or are they something stranger and more terrifying still?The answer may lie in the ancient city of Babylon, where two groups of refugees from 2037: three cosmonauts returning to Earth from the International Space Station, and three United Nations peacekeepers on a mission in Afghanistan have detected radio signals: the only such signals on the planet, apart from their own. The peacekeepers find allies in nineteenth-century British troops and in the armies of Alexander the Great. The astronauts, crash-landed in the steppes of Asia, join forces with the Mongol horde led by Genghis Khan. The two sides set out for Babylon, each determined to win the race for knowledge . . . and the power that lies within.Yet the real power is beyond human control, perhaps even human understanding. As two great armies face off before the gates of Babylon, it watches, waiting. . . .

    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.

    . . . The impossible has spawned the unthinkable. A military experiment in the year 2021 has thrust an American-led multinational armada back to 1942, right into the middle of the U.S. naval task force speeding toward Midway Atoll—and what was to be the most spectacular U.S. triumph of the entire war. Thousands died in the chaos, but the ripples had only begun. For these veterans of Pearl Harbor—led by Admirals Nimitz, Halsey, and Spruance—have never seen a helicopter, or a satellite link, or a nuclear weapon. And they’ve never encountered an African American colonel or a British naval commander who was a woman and half-Pakistani. While they embrace the armada’s awesome firepower, they may find the twenty-first century sailors themselves far from acceptable.Initial jubilation at news the Allies would win the war is quickly doused by the chilling realization that the time travelers themselves—by their very presence—have rendered history null and void. Celebration turns to dread when the possibility arises that other elements of the twenty-first century task force may have also made the trip—and might now be aiding Yamamoto and the Japanese.What happens next is anybody’s guess—and everybody’s nightmare. . . .From the Trade Paperback edition.
