The Ghost from the Grand Banks (Arthur C. Clarke Collection)
by Arthur C. ClarkeIn this near-future sci-fi novel by the author of 2001: A Space Odyssey, two companies competing to raise the Titanic find mystery among the wreckage. Two years before the centennial anniversary of the Titanic&’s demise, two powerful corporations compete to recover the legendary vessel from the floor of the North Atlantic. With the wreckage split in two, each company—one British and one Japanese—plans to use its spectacular technology to raise one half of the famous ship. But what they find deep beneath the ocean&’s surface is more than they bargained for. Discovered among the Titanic&’s remains are six perfectly preserved bodies, including one of a beautiful woman who was not listed among the ship&’s original passengers. Who was she—and what was her secret? The mission to find out becomes all-consuming and, for some, deadly. This fast-paced tale combines a centuries-old mystery with modern suspense and Clarke&’s visionary imagination—here concerned with future technologies, ecological crises, and the mysteries of fractal mathematics.

The Ghost of the Mary Celeste: A Novel (Vintage Contemporaries)
by Valerie MartinA captivating, atmospheric return to historical fiction that is every bit as convincing and engrossing as Martin's landmark Mary Reilly. In 1872 the American merchant vessel Mary Celeste was discovered adrift off the coast of Spain. Her cargo was intact and there was no sign of struggle, but the crew was gone. They were never found. This maritime mystery lies at the center of an intricate narrative branching through the highest levels of late-nineteenth-century literary society. While on a voyage to Africa, a rather hard-up and unproven young writer named Arthur Conan Doyle hears of the Mary Celeste and decides to write an outlandish short story about what took place. This story causes quite a sensation back in the United States, particularly between sought-after Philadelphia spiritualist medium Violet Petra and a rational-minded journalist named Phoebe Grant, who is seeking to expose Petra as a fraud. Then there is the family of the Mary Celeste's captain, a family linked to the sea for generations and marked repeatedly by tragedy. Each member of this ensemble cast holds a critical piece to the puzzle of the Mary Celeste. These three elements--a ship found sailing without a crew, a famous writer on the verge of enormous success, and the rise of an unorthodox and heretical religious fervor--converge in unexpected ways, in diaries, in letters, in safe harbors and rough seas. In a haunted, death-obsessed age, a ghost ship appearing in the mist is by turns a provocative mystery, an inspiration to creativity, and a tragic story of the disappearance of a family and of a bond between husband and wife that, for one moment, transcends the impenetrable barrier of death.

The Ghosts of K2
by Mick Conefrey"Most of us will never experience K2. Mick Conefrey leaves readers with both tremendous admiration for and an appreciation of the consequences for those who succeed in an adventure so physically, mentally, and emotionally taxing."- Kirkus Reviews At 28,251 ft, K2 might be almost 800 ft shorter than Everest, but it's a far harder climb. In this definitive account, Mick Conefrey grippingly describes the early attempts to reach the summit and provides a fascinating exploration of the first ascent's complex legacy. From the drug-addicted occultist Aleister Crowley to Achille Compagnoni and Lindo Lacedelli, the Italian duo who finally made it to the summit, The Ghosts of K2 charts how a slew of great men became fixated on this legendary mountain.Through exclusive interviews with surviving team members and their families, and unrivalled access to diaries and letters that have been archived around the world, Conefrey evokes the true atmosphere of the Savage Mountain and explores why it remains the 'mountaineer's mountain', despite a history steeped in controversy and death. Wrought with tension, and populated by tragic heroes and eccentric dreamers, The Ghosts of K2 is a masterpiece of mountaineering literature.

The Giants Go Camping
by Jane YolenFrom the author's website: The 1970's was a time of a great upsurge in children's publishing, and everyone was trying easy readers. This little book--and its prequel THE GIANTS FARM--were both my entry into that particular genre. The five giants live on Fe-Fi-Fo-Farm which is what I wanted to call our farm when we first moved here. (We ended up naming it Phoenix Farm, but at the urging of my children, I used the other name in a book!) Tomie's pictures manage to look like--Tomie! But the characters are really a metaphoric Yolen-Stemple family. And boy, did we love to go camping--all over New England mainly, but also down into West Virginia where David's family still lived. This book was a Jr. Literary Guild selection.

by Alison Hawthorne DemingThis unique collection of poems from diverse contemporary voices offers a range of perspectives on humans' complex relationship with animals, celebrating and bearing witness to the lives of animals both wild and domestic. Animals have long been a source of inspiration, sustenance, and companionship, and poems about and for animals are among the oldest traditions across human cultures. This collection of contemporary poems adds to this ancient lineage, celebrating animals for their beauty and intelligence; empathizing over their suffering; and hoping for their future, which is entwined with our own. The presence of an animal is a gift. The loss of an animal is a grief. To share such feelings through poetry is to create a community of caring for the creatures that accompany us on Earth. The Gift of Animals includes poems by some of today's most beloved poets, including Ellen Bass, Lucille Clifton, Michael Collier, Toi Derricotte, Rita Dove, Camille Dungy, Mark Doty, Nick Flynn, Jorie Graham, Joy Harjo, Terrance Hayes, Arthur Sze, Yusef Komunyakaa, Ada Limón, Aimee Nezhukumatathil, Craig Santos Perez, Paisley Rekdal, and more.
The Gift of Country Life
by Victor Carl FriesenMemories of farming in the 1940s conjure up images of horse-drawn farm machinery, grain stooks in fields, hay meadows, free-range chickens and cords of wood strategically placed for fuelling the kitchen range – all before farming became the highly technical, big-time operation it is now. Author Victor Carl Friesen was born and raised on a quarter section farm in Saskatchewan and still owns the "home place." It is there he still goes to renew his inner being. His poems, grouped into seasonal activities or observations, celebrate the rural world. Written in traditional blank verse, his poetry includes activities of yesteryear, his personal connections to rural life and his reverence for nature. Nature, as Henry David Thoreau said, is "one and continuous." Victor Carl Friesen lives and writes in Rosthern, Saskatchewan, but photographs nature anywhere. The first recipient of the Alberta Book Award, he is the author of five books including The Year Is a Circle.
The Gift of Good Land: Further Essays Cultural and Agricultural
by Wendell BerryIn the twenty-four essays of this collection, Wendell Berry stresses the carefully modulated harmonics of indivisibility in culture and agriculture, the interdependence, the wholeness, the oneness, of man, animals, the land, the weather, and the family. To touch one, he shows, is to tamper with them all. Here he continues issues first raised in "The Unsettling of America"; the problems addressed there are still with us and the solutions no nearer to hand, Mr. Berry writes of his journeys to the highlands of Peru, the deserts of southern Arizona, and the Amish country to study traditional agricultural practices. He writes of homesteading, tools and their uses, horses and tractors, family work, land reclamation, diversified land use. In the title essay Mr. Berry draws parallels between the Christian notion of stewardship and the Buddhist doctrine of "right livelihood." He develops the compelling argument that the "gift" of good land has strings attached: the recipient has it only as long as he practices responsible stewardship.
The Gift of the Deer

The Global Climate Regime and Transitional Justice (Routledge Advances in Climate Change Research)
by Jasmina Brankovic Sonja KlinskyGeopolitical changes combined with the increasing urgency of ambitious climate action have re-opened debates about justice and international climate policy. Mechanisms and insights from transitional justice have been used in over thirty countries across a range of conflicts at the interface of historical responsibility and imperatives for collective futures. However, lessons from transitional justice theory and practice have not been systematically explored in the climate context. The comparison gives rise to new ideas and strategies that help address climate change dilemmas. This book examines the potential of transitional justice insights to inform global climate governance. It lays out core structural similarities between current global climate governance tensions and transitional justice contexts. It explores how transitional justice approaches and mechanisms could be productively applied in the climate change context. These include responsibility mechanisms such as amnesties, legal accountability measures, and truth commissions, as well as reparations and institutional reform. The book then steps beyond reformist transitional justice practice to consider more transformative approaches, and uses this to explore a wider set of possibilities for the climate context. Each chapter presents one or more concrete proposals arrived at by using ideas from transitional justice and applying them to the justice tensions central to the global climate context. By combining these two fields the book provides a new framework through which to understand the challenges of addressing harms and strengthening collective climate action. This book will be of great interest to scholars and practitioners of climate change and transitional justice.
The Global Commons: An Introduction
by Elinor Ostrom Susan J. BuckVast areas of valuable resources unfettered by legal rights have, for centuries, been the central target of human exploitation and appropriation. The global commons -- Antarctica, the high seas and deep seabed minerals, the atmosphere, and space -- have remained exceptions only because access has been difficult or impossible, and the technology for successful extraction has been lacking. Now, technology has caught up with desire, and management regimes are needed to guide human use of these important resource domains.In The Global Commons, Susan Buck considers the history of human interactions with each of the global commons areas and provides a concise yet thorough account of the evolution of management regimes for each area. She explains historical underpinnings of international law, examines the stakeholders involved, and discusses current policy and problems associated with it.Buck applies key analytical concepts drawn from institutional analysis and regime theory to examine how legal and political concerns have affected the evolution of management regimes for the global commons. She presents in-depth case studies of each of the four regimes, outlining the historical evolution of the commons -- development of interest in exploiting the resource domain; conflicts among nations over the use of the commons; and efforts to design institutions to control access to the domains and to regulate their use -- and concluding with a description of the management regime that eventually emerged from the informal and formal negotiations.The Global Commons provides a clear, useful introduction to the subject that will be of interest to general readers as well as to students in international relations and international environmental law, and in environmental law and policy generally.
