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.

We live in a world positively teeming with threats and apocalyptic scenarios. Many of them are familiar: terrorism, deadly viruses, global warming and war, but many others most of us can't even imagine: self-replicating nanobots that can devour an entire planet, high-energy experiments that threaten to suck the Earth into a mini black hole, and even super-sophisticated scientific contraptions that can put an end to the entire universe.

It's The End Of The World...So Now What? It's a fact: in some form or another, Doomsday is upon us, and you need to be as ready as possible for any and every eventuality. Zombies? Bring 'em on! The Rapture? No problem! Yorggh, the Colossal Moronic Space Creature? Uh, not much can be done there. This book will help you separate the threat from the chaff with its handy dandy checklists and recommendations. While it is important to remember that survival is not guaranteed, this book will certainly* improve your odds of survival. Discover How To Survive Anything, Including: An invasion of space spiders The return of dinosaurs Global warming Man-eating ponies The planet eater thing from Star Trek *Certainty not guaranteed"

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.
