He will change their lives forever. . . . At fifteen, Natalie Ward believes her life is perfect. Growing up on a dairy farm in the mountains of British Columbia less than two miles from the American border, she knows little of the outside world. But she knows family. A family so close and loving that they are the envy of the nearby town of Atwood. Friends and neighbors, young and old alike, show up regularly on their farmhouse porch—all willing to share in the never-ending daily chores in exchange for a place at the Ward family table. Natalie cherishes her position as the only daughter of the beautiful Nettie Ward—the pride of the Catholic Ladies Auxiliary—and the town's milkman, Gus Ward—the darling of Atwood housewives. She adores her three brothers, especially the eldest, Boyer, whom she idolizes with a childlike worship. Like her mother, Natalie believes their lives are blessed, as rich and as sweet as the fresh milk that is their livelihood.Everything changes one hot July afternoon in 1966 when a long-haired stranger walks up the winding dirt road to their door. The arrival of this soft-spoken American, a Vietnam War resister, will test the morals and beliefs of the Ward family and their close-knit community. The catastrophic events that are set in motion will leave relationships shattered and Natalie separated from the family she loves in ways that she could never have imagined.Thirty-five years later, Natalie receives a late-night phone call from her now-estranged brother Boyer. Their mother is dying. Torn between the love of her mother and the fear of the past, Natalie returns to the town she has spent her entire adult life avoiding. As she travels back to her childhood home she steels herself against the bittersweet memories of that summer day in 1966 and the tragedy that followed. But before Natalie can find redemption, she must confront the secrets and horrors of a past she has desperately tried to forget.

And now the Leviathan has been awakened—an unfathomable creature whose wrath could single-handedly destroy the entire world. Scant hope remains—save for the possibly futile efforts of a lone elf, a mad witch, and a fallen hero charged with unraveling a series of divine riddles. But doom is inevitable, unless they can somehow break the powerful bonds of a fiendish, insidious possession.

They were our husbands, our fathers, our lovers, our sons. They were Americans and Marines. And this is their story: The Big War, Anton Myrer's panoramic novel of Marines in the Pacific in World War II. This is the story of Alan Newcombe, the Boston society Harvard man; Danny Kantaylis, the natural-born leader; Jay O'Neill, the barroom scrapper. Myrer does not glorify war; he does not flinch from describing what the actual experience of warfare was like for a desperate group of Marines trapped in some of the worst fighting conditions of the war. We learn about their lives at home and their fates on the battlefield.

Highly acclaimed by critics, The Foreign Student is the story of a young Korean man, scarred by war, and the deeply troubled daughter of a wealthy Southern American family. In 1955, a new student arrives at a small college in the Tennessee mountains. Chuck is shy, speaks English haltingly, and on the subject of his earlier life in Korea he will not speak at all. Then he meets Katherine, a beautiful and solitary young woman who, like Chuck, is haunted by some dark episode in her past. Without quite knowing why, these two outsiders are drawn together, each sensing in the other the possibility of salvation. Moving between the American South and South Korea, between an adolescent girl's sexual awakening and a young man's nightmarish memories of war, The Foreign Student is a powerful and emotionally gripping work of fiction.

Long-buried secrets go hand in hand with modern-day murder in this second thriller featuring attorney Thóra Gudmundsdóttir from Iceland's queen of crime fictionWhen the body of a young woman—badly beaten and with pins inserted into her feet—is found at a New Age health resort in a renovated farmhouse, lawyer and single mother of two Thóra Gudmundsdóttir is called upon to represent the chief suspect, the resort's owner. But upon her arrival she encounters more than a fresh corpse—local legend has it that the resort, located in the mystical region of Sn?fellsnes on Iceland's west coast, is haunted. At first Thóra dismisses the claims as nothing more than myth and superstition, but even she can't explain the bizarre occurrences she witnesses in her search for answers. As Thóra digs deeper into the farm's past, she discovers long-buried information on the property's disturbing history, and her once-solid view of reality begins to waver. Are the hauntings real, or just a case of folklore gone wildAnd, more important, does the farm's eerie past have something to do with the murderWhen another body is discovered—looking very much like the first—Thóra is forced to put aside her doubts and confront the horrors of the present before a twisted killer strikes again.With its confident plotting, chilling atmosphere, and smart, compelling heroine, My Soul to Take confirms Yrsa Sigurdardóttir as a new maven of mysteries.

The acclaimed author of Jesus' Son and Already Dead returns with a beautiful, haunting, and darkly comic novel. The Name of the World is a mesmerizing portrait of a professor at a Midwestern university who has been patient in his grief after an accident takes the lives of his wife and child and has permitted that grief to enlarge him.Michael Reed is living a posthumous life. In spite of outward appearances -- he holds a respectable university teaching position; he is an articulate and attractive addition to local social life -- he's a dead man walking.Nothing can touch Reed, nothing can move him, although he observes with a mordant clarity the lives whirling vigorously around him. Of his recent bereavement, nearly four years earlier, he observes, "I'm speaking as I'd speak of a change in the earth's climate, or the recent war."Facing the unwelcome end of his temporary stint at the university, Reed finds himself forced "to act like somebody who cares what happens to him. " Tentatively he begins to let himself make contact with a host of characters in this small academic town, souls who seem to have in common a tentativeness of their own. In this atmosphere characterized, as he says, "by cynicism, occasional brilliance, and small, polite terror," he manages, against all his expectations, to find people to light his way through his private labyrinth.Elegant and incisively observed, The Name of the World is Johnson at his best: poignant yet unsentimental, replete with the visionary imaginative detail for which his work is known. Here is a tour de force by one of the most astonishing writers at work today.
