Britain's best-loved comic genius Stephen Fry turns his celebrated wit and insight to unearthing the real America as he travels across the continent in his black taxicab. Stephen's account of his adventures is filled with his unique humour, insight and warmth in the fascinating book that orginally accompanied his journey for the BBC1 series. 'Stephen Fry is a treasure of the British Empire.' - The Guardian Stephen Fry has always loved America, in fact he came very close to being born there. Here, his fascination for the country and its people sees him embarking on an epic journey across America, visiting each of its 50 states to discover how such a huge diversity of people, cultures, languages, beliefs and landscapes combine to create such a remarkable nation. Starting on the eastern seaboard, Stephen zig-zags across the country in his London taxicab, talking to its hospitable citizens, listening to its music, visiting its landmarks, viewing small-town life and America's breath-taking landscapes - following wherever his curiosity leads him. Stephen meets a collection of remarkable individuals - American icons and unsung local heroes alike. Stephen starts his epic journey on the east coast and zig-zags across America, stopping in every state from Maine to Hawaii. En route he discovers the South Side of Chicago with blues legend Buddy Guy, catches up with Morgan Freeman in Mississippi, strides around with Ted Turner on his Montana ranch, marches with Zulus in New Orleans' Mardi Gras, and drums with the Sioux Nation in South Dakota; joins a Georgia family for thanksgiving, 'picks' with Bluegrass hillbillies, and finds himself in a Tennessee garden full of dead bodies. Whether in a club for failed gangsters (yes, those are real bullet holes) or celebrating Halloween in Salem (is there anywhere better?), Stephen is welcomed by the people of America - mayors, sheriffs, newspaper editors, park rangers, teachers and hobos, bringing to life the oddities and splendours of each locale. A celebration of the magnificent and the eccentric, the beautiful and the strange, Stephen Fry in America is our author's homage to this extraordinary country.

An exhilarating new collection of stories by the author of Richard & Judy-bestseller ‘Notes from an Exhibition’, combining wit and poignancy to illuminate experiences both common and uncommon. Love (and loathing) within families is dissected – a father makes an unexpected discovery about his son which is too hard for him to cope with. A son wreaks revenge through the power of cookery. Three generations of the same family gain freedom through the years in a once-despised caravan. A bored wife finds happiness when an old lag teaches her the art of angling. A dog-training lesson with a puppy who hasn’t grasped the meaning of ‘obedience’ leads to the discovery of a murder. Here too are music and silence – the sweetness and sadness of festivals, of the Church and of the control exercised by those in charge in small communities. This tremendously enjoyable collection of stories has the same wit, tenderness and acute psychological observation as Gale’s bestselling novels, including NOTES FROM AN EXHIBITION and the recent THE WHOLE DAY THROUGH. For Gale's many fans, GENTLEMAN’S RELISH is certain to be a real treat.

A searing, unflinching and deeply moving account of Marya Hornbacher’s personal experience of living with bipolar disorder. From the age of six, Marya Hornbacher knew that something was terribly wrong with her, manifesting itself in anorexia and bulimia which she documented in her bestselling memoir ‘Wasted’. But it was only eighteen years later that she learned the true underlying reason for her distress: bipolar disorder. In this new, equally raw and frank account, Marya Hornbacher tells the story of her ongoing battle with this most pervasive and devastating of mental illnesses; how, as she puts it, ‘it crept over me like a vine, sending out tentative shoots in my childhood, taking deeper root in my adolescence, growing stronger in my early adulthood, eventually covering my body and face until I was unrecognizable, trapped, immobilized’. She recounts the soaring highs and obliterating lows of her condition; the savage moodswings and impossible strains it placed on her relationships; the physical danger it has occasionally put her in; the endless cycle of illness and recovery. She also tackles the paradoxical aspects of bipolar disorder – how it has been the drive behind some of her most creative work – and the reality of a life lived in limbo, ‘caught between the world of the mad and the world of the sane’. Yet for all the torment it documents, this is a book about survival, about living day to day with bipolar disorder – the constant round of therapy and medication – and managing it. As well as her own highly personal story, the book includes interviews with family, spouses and friends of sufferers, the people who help their loved ones carry on. Visceral and inspiring, lyrical and sometimes even funny, ‘Madness’ will take its place alongside other classics of the genre such as ‘An Unquiet Mind’ and ‘Girl, Interrupted’.

She flees to the south, where her father finds a young foundling of the same age among the refugee trains to replace the boy. He makes her promise never to tell anyone, including her husband – still fighting on the Russian front – that the boy is not her own. Nobody will know the difference. 2008. Gregor Liedmann is a Jewish man now in his sixties. He's an old rocker who ran away from home, a trumpet player, a revolutionary stone-thrower left over from the 1968 generation. On a single day spent gathering fruit in an orchard outside Berlin with family and friends, Gregor looks back over his life, sifting through fact and memory in order to establish the truth. What happened on that journey south in the final days of the war? Why did his grandfather Emil disappear, and why did the Gestapo torture uncle Max? Here, in the calmness of the orchard, along with his ex-wife Mara and son Daniel, Gregor tries to unlock the secret of his past. In his first novel since the best-selling memoir ‘The Speckled People’, Hugo Hamilton has created a truly compelling story of lost identity, and a remarkable reflection on the ambiguity of belonging.

The natural history of an ordinary English country parish was one of the first subjects that suggested themselves when the New Naturalist series was planned. Collins are delighted to announce the republication in facsimile form of the first editions of the very first volumes in the New Naturalist Library. Originally planned in the darkest days of World War II and first published in 1945, this series is the longest running nature series in the world. It is a reflection of the quality of the authors and the books they wrote, that they are still sought after 73 years later. The books will be identical in every way to the original first editions, including the iconic jackets by Clifford and Rosemary Ellis. The natural history of an ordinary English country parish was one of the first subjects that suggested themselves when the New Naturalist series was planned. Being chiefly farmland and therefore practically all man-made, most country parishes are extremely complex from the naturalist's point of view and also inevitably contain a vast amount of human history. Any attempt to describe their plants and animals has to be closely related with the ways of man himself, who must be regarded as the chief element in the community - a fact which has been obvious enough to naturalists ever since the days of Gilbert White. For this book we were fortunate to find an author who combined a thorough all-round knowledge of natural history with a sound insight into human customs, history, pastimes and farming methods. Arnold Boyd lived in Cheshire all his life - and in keeping with the best tradition of English amateur naturalists, he excelled as a collector of facts, as is apparent from his previous books, his writing in the Manchester Guardian and other journals, and in his assistant editorship of British Birds. By weaving together his collection of facts he presents us with a book of remarkable unity and which shows a wide grasp of every aspect of the living communities. This charming yet erudite portrait will protect his beloved parish for ever from the ravages of human forgetfulness.

The use of natural and seeded grass pastures for the feeding of livestock and other unfamiliar uses for the ubiquitous grass family are described in this succinct and beautifully illustrated work. This edition is exclusive to newnaturalists.com The New Naturalist series has already covered many facets of the interrelationship between man and nature, but the grass family is probably the most important man in the whole plant kingdom - just how important is shown in this book. Dr. Moore, the Principal of Seale Hayne Agricultural College in Devon, is our leading authority on grasses and their utilization. His special interest is the use of natural and seeded grass pastures for the feeding of livestock. Striking advances have been made in recent years in the improvement of such pastures and Dr. Moore deals very fully with this vital link in the feeding of the human race; but he also covers that other equally important role of the grass family in our economy, the cultivation of cereal crops for the production of grain. Grass lawns and playing fields form a centre-piece in most British gardens and public parks and there is a chapter on these, but the horticultural value of grasses as ornamental plants in herbaceous borders and woodland gardens is less well known. These and many other unfamiliar uses for the ubiquitous grass family are described in this succinct and beautifully illustrated work.

Pesticides and Pollution examines the problems of pollution of air, land, river, and the sea, by herbicides, pesticides, sewage, industrial effluents, gases, radiation, leakages, over-drainage, mistakes and mismanagement, in Britain today. From an objective and scientific standpoint, Dr. Mellanby examines the problems of pollution of air, land, river, and the sea, by herbicides, pesticides, sewage, industrial effluents, gases, radiation, leakages, over-drainage, mistakes and mismanagement, in Britain to-day. He sets out to placate neither farmers nor naturalists, but to explain in each case what is happening, to point to both dangers and practical necessities, and to discuss what steps should be taken. Dr. Mellanby is Director of the Nature Conservancy's Monks Wood Experimental Station, was head of the Entomology department at Rothamsted, and for many years before that did research in medical entomology both in Britain and the tropics.

Leslie Brown's account of our 15 resident, 7 vagrant and 2 migrant species of eagles, falcons, hawks and vultures in Britain presents a great mass of scientific information about our birds of prey in a manner as attractive to the general reader as to the dedicated ornithologist. The diurnal raptors are among the most arresting and dramatic of British bird species, from the magnificent and immense golden eagle of the Highlands to the more widespread but equally spectacular peregrine falcon and the frequent and adaptable kestrel of motorways and urban ledges. Leslie Brown's account of our 15 resident, 7 vagrant and 2 migrant species of eagles, falcons, hawks and vultures in Britain presents a great mass of scientific information about these birds in a manner as attractive to the general reader as to the dedicated ornithologist. Each of the resident species is discussed in detail - its status, past and present; its feeding and hunting behaviour; its life history; its breeding behaviour; migration and the threats to its survival. Then the biology of the birds of prey, changes in their habitat and status, their food habits, breeding behaviour, their territories and populations are examined in depth in separate chapters. An acknowledged world authority on birds of prey - co-author with Dean Amadon of Eagles, Hawks and Falcons of the World, and author of many other books besides - Leslie Brown is immensely enthusiastic; and the many tables, maps, figures and bibliography are all indicative of the thoroughness of his research. Also illustrated with 40 superb black and white photographs.

This is the first survey of the islands' natural history, complete in one volume. Because Orkney is exceptional, it is vital reading for the serious naturalist, as well as for being a comprehensive and absorbing guide for every visitor. This edition is exclusive to newnaturalists.com Orkney is a very special place for naturalists. Closer to Oslo than to London, its geography and climate create quite distinct environmental conditions - even though it is only six miles from the Scottish mainland. On these islands of fierce gales, long summer days and long winter nights, the wildlife has adapted in intriguing ways… Starlings adapt to ground-nesting…local sheep eat seaweed…and there are voles exclusive to Orkney. Here is one of the very few areas where the rare and delicate Scottish Primrose thrives…where you find the British stronghold of the Hen Harrier, and vast colonies of seabirds and seals. This is the first - and long-needed - survey of the islands' natural history, complete in one volume. Because Orkney is exceptional, it is vital reading for the serious naturalist, as well as for being a comprehensive and absorbing guide for every visitor. In his tracing of the island's evolution from its geological creation to the effects of oil technology; in the detailed, yet fascinating exploration of the plants and animals (and where best to see them), Professor Berry's expertise and enthusiasm is backed by that of local specialists, and Orkney's long tradition of natural history study. Appendices include definitive lists of all the species of flora and fauna on record, and an extensive bibliography.

The soil is one of the great unsung disappearing resources, with over 100m tonnes being destroyed every year. This edition is exclusive to newnaturalists.com The soil is the work place of farmers and gardeners, but it is also a fascinating environment inhabited by insects that can leap into the air to a record height, multilegged scavengers that are vital to the decomposition of plant matter and the long, thin, entwining strands of thousands of species of fungi. Although soil plays a vital role in the functioning of the world, it has often been overlooked, mainly because it contains a huge range of different fields, all of which have become specialities in their own right. This book brings together specialists in these fields to give a broad overview of the staggering advances that have been made since Sir John Russel's The World Of Soil was published in this series in 1947. The first two chapters introduce the physical structure of the soil. The next four chapters deal with the specific animals and plants and how they exploit this environment. The final four chapters describe how these animals interact and how man has used and abused the soil in his striving to gain more and more from this resource.
