Connie Willis draws upon her understanding of the universalities of human nature to explore the ageless issues of evil, suffering, and the indomitable will of the human spirit. “A tour de force.”—The New York Times Book Review For Kivrin, preparing to travel back in time to study one of the deadliest eras in humanity’s history was as simple as receiving inoculations against the diseases of the fourteenth century and inventing an alibi for a woman traveling alone. For her instructors in the twenty-first century, it meant painstaking calculations and careful monitoring of the rendezvous location where Kivrin would be received. But a crisis strangely linking past and future strands Kivrin in a bygone age as her fellows try desperately to rescue her. In a time of superstition and fear, Kivrin—barely of age herself—finds she has become an unlikely angel of hope during one of history’s darkest hours.

How might the world as we know it end? In this illustrated guide, How Stuff Works author Marshall Brain explores myriad doomsday scenarios and the science behind them. What if the unimaginable happens? A nuclear bomb detonates over a major city, for example, or a deadly virus infects millions around the world. There are other disasters we don’t even have to imagine because they’ve already occurred, like violent hurricanes or cataclysmic tsunamis that have caused horrific loss of life and damage. In The Doomsday Book, Marshall Brain explains how everything finally ends—the decimation of nations and cities, of civilization, of humanity, of all life on Earth. Brain takes a deep dive into a wide range of doomsday narratives, including manmade events such as an electromagnetic pulse attack, a deadly pandemic, and nuclear warfare; devastating natural phenomena, such as an eruption from a super-volcano, the collapse of the Gulf Stream, or lethal solar flares; and science-fiction scenarios where robots take over or aliens invade. Each compelling chapter provides a detailed description of the situation, the science behind it, and ways to prevent or prepare for its occurrence. With fun graphics and eye-catching photographs at every turn, The Doomsday Book will be the last book you’ll ever have to read about the last days on Earth. Scenarios include: - Asteroid Strike: a massive asteroid could obliterate life—just as it might have killed the dinosaurs. - Gray Goo: self-replicating nanobots engulf the planet. - Grid Attack: an attack on our power grid shuts down the internet, affecting airports, banks, computers, food delivery, medical devices, and the entire economic system. - Gulf Stream collapse: the shutdown of this important ocean current causes temperatures to plummet. - Ocean acidification: if the oceans’ pH levels shift due to a rise in carbon dioxide, all marine life could die.

A fundamental part of English heritage, the Domesday Book is unique in medieval history, recording an entire country and its inhabitants town by town, with over 12,500 entries. In this lavishly illustrated book, Elizabeth Hallam and Thomas Hinde examine the background to the nine-hundred-year-old document, setting the events of 1086 into the context of the medieval world. It is a remarkable tribute to English continuity that almost all of the Domesday settlements still exist in some form or another.
