The latest in the New Naturalist series documents the parks and green spaces unique to Britain's cities – and the wildlife that has flourished in these habitats. Not since Richard Fitter’s landmark publication in 1945, ‘London’s Natural History’ – volume 3 in the New Naturalist series – has there been a comprehensive guide to urban natural history. Since then there have been major advances in the conservation of nature in our towns and cities, and there is even more to say about how animals and plants have adapted, in varying degrees, to urbanisation. But this is not merely an exploration of natural history within the urban environment – David Goode uses his knowledge of urban ecology to describe the range of habitats and species which exist within urban areas, and shows how our understanding is being applied to encourage a greater variety of nature into towns and cities. He illustrates how an ecological approach can be incorporated within planning and design to create a range of habitats from tiny oases to extensive new urban woodland and wetlands.

‘I watched the mirror for a last view, for now, of the frozen mountains of Glen Coe. As the road bent and the outline of Buachaille Etive Mor slid into sight, I did what I always did, and always would. I felt for that flutter of awe and that indefinable, unmistakable quickening of the pulse.’ In the late 18th century, mountains shifted from being universally reviled to becoming the most inspiring things on earth. Simply put, the monsters became muses – and an entire artistic movement was born. This movement became a love affair, the love affair became an obsession, and gradually but surely, obsession became lifestyle as mountains became stitched into the fabric of the British cultural tapestry. In his compelling new book, Simon Ingram explores how mountains became such a preoccupation for the modern western imagination, weaving his own adventures into a powerful narrative which provides a kind of experiential hit list for people who don’t have the time nor the will to climb a thousand mountains. For some of these mountains, the most amazing thing about them might be the journey they’ve taken to get here. Others, the tales of science, endeavour and art that have played out on their slopes. The mythology they’re drenched in. The history they’ve seen. The genius they’ve inspired. The danger that draws people to them. The life that clusters around them, human and otherwise. The extreme weather they conjure. The adventure they fuel. The way that some raise the hairs on the back of your neck, and trigger powerful, strange emotions. And moreover, what they’re like to be amidst, under, on – just what that indefinable quality is that the British mountains wield which takes possession of you so powerfully, and never goes away. Ingram takes us high into the rafters of Britain’s most forbidding, unflinching and unchanging wild places through all the seasons of the year – from the first blush of spring to the deepest, darkest bite of the mountain winter. From Beinn Dearg to Ben Nevis, he takes us on a journey spanning sixteen of Britain’s most evocative mountainous landscapes, and what they mean to us today.

The inspiration behind the powerful new film starring Gugu Mbatha-Raw, Tom Wilkinson and Emily Watson, this is the story of Dido Belle, whose adoption by an aristocratic family challenged the conventions of 18th century England. In one of the most famous portraits in the world, a pretty girl walks through the grounds of Kenwood House, a vision of aristocratic refinement. But the eye is drawn to the beautiful woman on her right. Pointing at her own cheek, she playfully acknowledges her remarkable position in eighteenth-century society. For Dido Belle was the illegitimate, mixed-race daughter of a Royal Navy captain and a slave woman, adopted by the Earl of Mansfield. As Lord Chief Justice of England he would preside over the notorious Zong case – the drowning of 142 slaves by an unscrupulous shipping company. His ruling provided the legal underpinning to the abolition of slavery in Britain. From the privileged yet unequal lives of Dido and her cousin Elizabeth, to the horrific treatment of African slaves, Paula Byrne – the bestselling author of ‘The Real Jane Austen’ – vividly narrates the story of a family that defied convention, the legal trial that exposed the cruelties of slavery and the woman who challenged notions of race at the highest rank.

The Collins Nature Library is a new series of classic British nature writing – reissues of long-lost seminal works. The titles have been chosen by one of Britain’s best known and highly acclaimed nature writers, Robert Macfarlane, who has also written new introductions that put these classics into a modern context. Nature Near London is a collection of observational pieces from locations near London at the end of the 19th Century. The depth of knowledge and of familiarity with particular places and particular species gives the impression that each small piece is the product of many years of observation. His style of observation is a work in miniature – cataloguing the most minute details; the dancing of a flower in the wind or the darting of a cautious trout. The chapters centre on a special place, a certain species, geographical feature or habitat – everything from orchards and copses to rivers and streams. Jefferies always explains the typical behaviour of whatever he is describing, and often contrasts what he sees with what one would expect to see in another part of the country, or in a different season. His knowledge of flowers is wide-ranging, and his ability to describe one particular patch of a field in such a specific way brings tremendous variety to the chapters that make up the book. The final chapters are a departure – both from the character of the rest of the book, and from London itself, as Jefferies boards the train to Brighton. Suddenly he is describing people and their relationship to nature, as much as nature itself. The scope widens, less a work in miniature, more surging towards a triumphant end as Jefferies becomes ever more philosophical. 100 years on, the book becomes even more relevant than when it was published – as a reminder of the dangers of unrelenting urbanisation, but also the context of the trend that aims to recreate nature where we need it most – around our cities. Nature near London is a portrait of what we’ve lost, and a reminder of nature’s positive and calming influence. Going along with Jefferies is like taking an afternoon stroll out of the city, without having to leave your armchair.

‘Boldly planned, bravely executed and brilliantly accomplished’ was Margaret Thatcher’s assessment of the Falklands campaign. But what did the war mean to the men in the trenches and below decks? This gripping first-hand account of the Falklands War, written by bestselling military historian Patrick Bishop and Sunday Times Editor John Witherow, reveals the true experiences of the British soldiers and seamen on the front line. The authors, then rookie reporters, lived alongside the fighting men, experiencing the daily realities of a British task force that was hugely outnumbered on a barren island 8,000 miles from home. The Falklands: The Winter War looks at the covert role of the SAS and the heroic death of Colonel ‘H’ Jones at Goose Green, and considers just how close Britain came to defeat. This is an extraordinarily frank and unsparing account of a military campaign that has held a defining place within the British national conscience since victory in 1982.

A thrilling account of treachery, loyalty and martyrdom in Elizabethan England from an exceptional new writer. As darkness fell on the evening of Friday, 28 October 1588, just weeks after the defeat of the Spanish Armada, two young Englishmen landed in secret on a Norfolk beach. They were Jesuit priests. Their aim was to achieve by force of argument what the Armada had failed to do by force of arms: return England to the Catholic Church. Eighteen years later their mission had been shattered by the actions of a small group of terrorists, the Gunpowder Plotters; they themselves had been accused of designing ‘that most horrid and hellish conspiracy’; and the future of every Catholic they had come to save depended on the silence of an Oxford joiner, builder of priest-holes, being tortured in the Tower of London. ‘God’s Secret Agents’ tells the story of Elizabeth’s ‘other’ England, a country at war with an unseen enemy, a country peopled – according to popular pamphlets and Government proclamations – with potential traitors, fifth-columnists and assassins. And it tells this story from the perspective of that unseen ‘enemy’, England’s Catholics, a beleaguered, alienated minority, struggling to uphold its faith. Ultimately, ‘God’s Secret Agents’ is the story of men who would die for their cause undone by men who would kill for it.

The dramatic untold story of the three tragic Grey sisters, all heirs to the Tudor throne, all victims to their royal blood. Lady Jane Grey is an icon of innocence abused. Remembered as the ‘Nine Days Queen’, she has been mythologized as a child-woman sacrificed to political expedience. But behind the legend lay a rebellious adolescent who became a leader, and no mere victim. Growing up in her shadow, Jane’s sisters Katherine and Mary would have to tread carefully to survive. The dramatic lives of the younger Grey sisters remain little known, but both women became heirs and rivals to the Tudor monarchs, Mary and Elizabeth I. To gain Queen Mary’s trust, teenaged Katherine ignored Jane’s final request not to change her religion, only to risk her life with a marriage that threatened Queen Elizabeth’s throne. While Katherine’s friends fought to save her, the youngest Grey sister, Mary, stayed at court. Though too poor and plain to be significant, she looked set to escape the burden of her royal blood. But then she too fell in love and incurred the Queen’s fury. Exploding the many myths of Lady Jane’s life, and casting fresh light onto Elizabeth’s reign, acclaimed historian Leanda de Lisle brings the Grey sisters’ tumultuous world to life: at a time when a royal marriage could gain you a kingdom, or cost you everything.

Talented historian Maya Jasonoff offers an alternative history of the British Empire. It is not about conquest – but rather a collection of startling and fascinating personal accounts of cross-cultural exchange from those who found themselves on the edges of Empire. A Palladian mansion filled with Western art in the centre of old Calcutta, the Mughal Emperor’s letters in an archive in the French Alps, the names of Italian adventurers scratched into the walls of Egyptian temples: in this imaginative book, Maya Jasanoff delves into the stories behind artefacts like these to uncover the lives of collectors in India and Egypt who lived on the frontiers of European empire. ‘Edge of Empire’ traces their exploits to tell an intimate history of imperialism. Written and researched on four continents, ‘Edge of Empire’ tells a story about the making of European empires, ones that break away from the grand narratives of power, exploitation, and resistance, to delve into the personal dimensions of imperialism. She asks what people brought to imperial frontiers and what they took away, and what motives drove them, whether ambition, opportunism, curiosity or greed. This rich and compelling book enters a world where people lived, loved and died, and identified with each other across cultures much more than our prejudices about ‘Empire’ might suggest.

A delightful and fascinating social history of Victorians at leisure, told through the letters, diaries, journals and novels of nineteenth-century men and women, from the author of the bestselling ‘The Victorian House’. Imagine a world where only one in five people owns a book, where just one in ten has a knife or a fork – a world where five people out of every six do not own a cup to hold a hot drink. That was what England was like in the early eighteenth century. Yet by the close of the nineteenth century, the Industrial Revolution had brought with it not just factories, railways, mines and machines but also fashion, travel, leisure and pleasure. Leisure became an industry – a cornucopia of excitement for the masses – and it was spread by newspapers, advertising, promotions and publicity – all of which were eighteenth-century creations. It was Josiah Wedgwood and his colleagues who invented money-back guarantees, free delivery and celebrity endorsements. New technology such as the railways brought audiences to ever-more-elaborate extravaganzas, whether it was theatrical spectaculars with breathtaking pyrotechnics and hundreds of extras – ‘hippodramas' recreating the battle of Waterloo – or the Great Exhibition itself, proudly displaying 'the products of all quarters of the globe' under twenty-two acres of the sparkling 'Crystal Palace'. In ‘Consuming Passions’, the bestselling author of ‘The Victorian House’ explores this dramatic revolution in science, technology and industry – and how a world of thrilling sensation, lavish spectacle and unimaginable theatricality was born.

‘Why the hell did you write that insurance policy for a 96-year-old man going on a skiing holiday?’ shouted the manager at the travel clerk.‘Well,’ said the clerk, ‘I checked the records and no one of that age has ever had a skiing accident.’The skier came to a stop at the end of the run and threw his poles, hat and gloves to the ground as he snorted in disgust, ‘I’ve never skied so badly before!’‘Oh,’ probed an interested instructor, ‘you mean to say you’ve skied before?’
