Seven o’clock on a Monday morning, five hundred years after the end of the world, and goblins had been at the cellar again. . . . Not that anyone would admit it was goblins. In Maddy Smith’s world, order rules. Chaos, old gods, fairies, goblins, magic, glamours–all of these were supposedly vanquished centuries ago. But Maddy knows that a small bit of magic has survived. The “ruinmark” she was born with on her palm proves it–and makes the other villagers fearful that she is a witch (though helpful in dealing with the goblins-in-the-cellar problem). But the mysterious traveler One-Eye sees Maddy’s mark not as a defect, but as a destiny. And Maddy will need every scrap of forbidden magic One-Eye can teach her if she is to survive that destiny.

Chyna Shepherd is a twenty-six-year-old woman whose deeply troubled childhood taught her the hard rules of survival, and whose adult life has been an unrelenting struggle for self-respect and safety. Now rare trust has blossomed for Chyna into friendship with the woman whose family home she is visiting for the weekend: a farm in the Napa Valley surrounded by vineyards and hills, which Chyna can see from the guest-room window where she sits at one o'clock in the morning, fully dressed, unable to sleep. Suspicions she learned in childhood still make her uneasy in unfamiliar houses--even this one, where her closest friend is sound asleep down the hall. And in this case her most disturbing instincts prove reliable. A man has entered the house, a man who lives for one purpose: to satisfy all appetites as they arise, to immerse himself in sensation, to live without fear, remorse, or limits--to live with intensity.His name is Edgler Foreman Vess. He likes to make words with the letters from his name--GOD, DEMON, SAVE, RAGE, ANGER, FEAR, FOREVER, are just a few of them--and then makes sentences with the words. One of his favorites, GOD FEARS ME, is sometimes the last thing he whispers to his victims. Edgler Vess is a self-proclaimed "homicidal adventurer": On this night, his adventure--murdering everyone in the house--becomes Chyna's long nightmare.Trapped in Vess's deadly orbit, Chyna thinks only of getting out alive. But when she inadvertently learns the identity of Vess's intended next victim, waiting for him far from Napa Valley, Chyna is gripped with concern for this other person, who is as innocent as Chyna, and as endangered. Driven now by a sense of responsibility for another, by a purpose and meaning beyond mere self-preservation, Chyna rises to unexpected heights of courage and daring--her only hope as the threat of Edgler Foreman Vess closes in and grows more horrifying moment by moment.Intensity unfolds over the course of just twenty-four hours, but within that brief time frame, Dean Koontz gives us what is perhaps his most inventive, emotionally intricate, and terrifyingly suspenseful novel yet.

Seligman draws on more than twenty years of clinical research to demonstrate how optimism enchances the quality of life, and how anyone can learn to practice it.

With generous additional advice on how to encourage optimistic behavior at school, at work and in children, Learned Optimism is both profound and practical–and valuable for every phase of life.From the Trade Paperback edition.

"This book recounts the five-day history of a major American scientific crisis. As in most crises, the events surrounding the Andromeda Strain were a compound of foresight and foolishness, innocence and ignorance. Nearly everyone involved had moments of great brilliance, and moments of unaccountable stupidity...."Thus begins this extraordinary novel of the world's first space-age biological emergency.The Andromeda Strain sets forth with almost documentary verisimilitude the unfolding story of "Project Wildfire" -- the crash mobilization of the nation's highest scientific and medical resources when an unmanned research satellite returns to earth mysteriously and lethally contaminated.Four American scientists, chosen in advance for their experimental achievements in the fields of clinical microbiology, epidemiology, pathology, and electrolyte chemistry, are summoned under conditions of total news blackout and utmost urgency to Wildfire's secret laboratory five stories beneath the Nevada desert. There -- surrounded by banks of the most sophisticated computer-assisted equipment, and sealed off from the outside world except for a telecommunications link with the national security apparatus -- they work against the threat of a worldwide epidemic to find an antidote to the unknown microorganism that has inexplicably killed all but two inhabitants (an elderly derelict and an infant) of the tiny Arizona town where the satellite was retrieved. Step by step they begin to unravel the puzzle of the Andromeda Strain, until, terrifyingly, their microbacterial "adversary" ruptures the hypersterile seal of the laboratory and their already desperate search for a biomedical answer becomes a split-second race against an atomic deadline.With its narrative force, its scientific detail, its suspense -- as four brilliant individualists work together under ultimate pressure -- this novel makes real for the reader the real world of today's science and medicine at the top-secret levels of the Science-Space-Military high command.The author is a trained scientist. Newspaper stories from NASA that have appeared since the completion of the manuscript read like details from The Andromeda Strain...

In January 1692 in Salem Village, Massachusetts, two young girls began to suffer from inexplicable fits. Seventeen months later, after legal action had been taken against 144 people—20 of them put to death—the ignominious Salem witchcraft trials finally came to an end. Now, Mary Beth Norton—one of our most ad-mired historians—gives us a unique account of the events at Salem, helping us to understand them as they were understood by those who lived through the frenzy. Describing the situation from a seventeenth-century perspective, Norton examines the crucial turning points, the accusers, the confessors, the judges, and the accused, among whom were thirty-eight men. She shows how the situation spiraled out of control following a cascade of accusations beginning in mid-April. She explores the role of gossip and delves into the question of why women and girls under the age of twenty-five, who were the most active accusers and who would normally be ignored by male magistrates, were suddenly given absolute credence. Most important of all, Norton moves beyond the immediate vicinity of Salem to demonstrate how the Indian wars on the Maine frontier in the last quarter of that century stunned the collective mindset of northeastern New England and convinced virtually everyone that they were in the devil’s snare. And she makes clear that ultimate responsibility for allowing the crisis to reach the heights it did must fall on the colony’s governor, council, and judges.A vivid, authoritative historical evocation and exploration that will alter forever the way we think about one of the most perennially fascinating and horrifying events in our history.
