Bikini Atoll
The Empire of Japan formally surrendered to the Allies on 2 September 1945, following the dropping of the atomic bombs on Hiroshima and Nagasaki. While the fighting had ended, a new weapon had been unleashed onto the world stage that nations rushed frantically to develop and master. The USA needed somewhere extremely remote to conduct its experimental nuclear weapons testing. They chose Bikini Atoll – a beautiful Pacific coral atoll in the Marshall Islands in the middle of the Pacific and perhaps the most remote group of islands on the planet. The initial nuclear experiments were assigned the codename Operation Crossroads. The 167 local islanders were moved out of their once tranquil tropical paradise whilst American, and captured German and Japanese, battleships, cruisers, destroyers, submarines, and aircraft carriers were moved to the lagoon and moored strategically around the test area so that the effects of a nuclear blast on them could be studied. In total, the US conducted twenty-five nuclear tests on the atoll between 1946 and 1957. Unsurprisingly, Bikini was closed to all visitors until the 1990s. But with radiation in the waters of the lagoon at safe levels, Bikini was able to open its lagoon to divers - and hosting wrecks of some of the most famous shipwrecks of the Second World War, Bikini soon became a magnet for technical divers. Today, diving the Bikini Atoll wrecks is seen as the ultimate diving experience. A renowned diver, Rod Macdonald is famous for his books about the Second World War shipwrecks of Truk Lagoon and Palau. He has now investigated the Bikini wrecks and presents a detailed analysis of the ABLE and BAKER nuclear tests, alongside a stunning collection of unique images of the wrecks, which graphically portray the effects of the most devastating weapons known to mankind.
The Doolittle Raiders’ Battle for Survival
This is an extraordinary account of courage, survival, and sacrifice in the aftermath of one of the Second World War’s most daring missions. While the Doolittle Raid on Japan is often celebrated for its audacity and strategic importance, this book focuses on the tortuous journey of the Raiders once their mission was complete, as they descended – quite literally – into the unknown. After striking targets in Japan on 18 April 1942, the Raiders, flying their North American B-25 bombers, faced an impossible challenge: reaching safety with dwindling fuel reserves. While one crew landed in the Soviet Union, the remaining fifteen crash-landed or baled out over Japanese-occupied China, initiating a desperate struggle for survival. Spread across rugged terrain, the Raiders battled severe weather, injuries, starvation, and the constant threat of capture or death at the hand of the Japanese forces. This book delves deeply into the human stories of the Doolittle Raiders during their escape through hostile territory. It highlights the critical role played by Chinese villagers and resistance fighters who risked – and often lost – their lives to protect the stranded Americans. Through their heroic efforts, many Raiders made it to safety, but not without significant losses. The Japanese retaliated mercilessly against the Chinese in one of the largest manhunts the Japanese ever mounted, killing tens of thousands in the Zhejiang-Jiangxi Campaign, underscoring the devastating costs of the mission. With its rich blend of action, human drama, and historical depth, and drawing on declassified military records, personal diaries, and interviews with descendants of the Raiders and their Chinese allies, The Doolittle Raiders’ Battle of Survival vividly reconstructs the Raiders’ perilous journey to safety – or not. From parachute landings into dense forests and dangerous mountain crossings to encounters with guerrilla fighters and near-capture by Japanese troops, the narrative is both suspenseful and deeply moving.
A History of Romance Novels
When you pick up the latest Emily Henry novel, or settle in for an evening with the newest volume of your favorite romantasy, you are taking part in a process stretching back two millennia. The ancient Greeks considered it a highlight of one's life to hear with one's own ears the words of the great romantic poets of their day. The Romans enjoyed sprawling romantic epics that only reunited their lovers after continent-spanning struggles against foreign armies, pirates, and treacherous monarchs. The Middle Ages sung hushed stories of lust far from the ears of the Church, while its great poets probed the darker boundaries of courtly love, and the writers of the seventeenth century delighted in giving young women ten-volume romances, delivered over the course of a decade, to fill their bookshelves and lonely hours. Writing about love, its complexities, and resolutions, has been a part of the literary tradition since its inception, but it is only in the last three centuries that the format has grown into the publishing juggernaut we know today. From the intensely observed novels of Jane Austen, through the great Sensation Novels of the 1860s that fused romance and mystery, and into the great industrial and marketing machine that was Mills & Boon and Harlequin at their height, new developments in publishing have linked up with new ideas about womanhood, sex, and romance, to produce an ever-evolving approach to the romance novel, culminating in our own modern Golden Age, where more people from more backgrounds are writing more types of romance than ever before for a readership than is larger than it has ever been, and is consuming its favourite literary form in convenient new formats. A History of Romance Novels: From Trembling Innocents to Hunky Werewolves explores the long story of our love affair with love stories, during both its eras of creative flourishing, and the long periods of industrially motivated stagnation, to give even the most dedicated romance reader a few new veins to mine, and a few more characters to fall in love with.
A History of the Fedon Rebellion
In 1795, an attempted revolution in the British colony of Grenada took place, led by the enigmatic Julien Fédon. While ultimately unsuccessful, this bloody uprising shifted the balance of power in the Caribbean and fundamentally changed the way the British crown ran its colonies. But what might have happened had Fédon's rebellion played out differently, with a more consistent message on enslaved emancipation and mixed-race empowermen? n this compelling new book, historian Kit Candlin tells the captivating story of the rebellion in Grenada, full of secret plans and clandestine meetings, frayed nerves and paranoia, in a highly unstable, interconnected world. Its protagonists form a diverse collection of transient adventurers, itinerant planters, free people of colour and the enslaved – the flotsam of one of the most polyglot, contested and liminal places in the Atlantic World. While not as well known as its Haitian counterpart, the Grenadian revolution played a crucial role in shaping the British Empire, and understanding its history brings further nuance and context to the bitter legacy of colonialism in the region. Candlin's rich tale of what happened – and what might have been – is not to be missed by anyone interested in the Caribbean in the Age of Revolution.
The Politics of Common Reading
Examines the transformation of vernacular knowledge during a pivotal period of modern Chinese history, 1894 to 1954. What did common readers read in the midst of the revolutions that punctuated China’s long Republic (1894–1954)? How did they manage the often-unprecedented challenges of the era? What did they know and how did they know it? In The Politics of Common Reading, Joan Judge traces the unfolding of a consequential politics of accommodation that engaged commoners as knowers rather than as an unenlightened mass. A response to the institutional failures of the era, this politics was enacted through an informal knowledge infrastructure comprised of low-budget publishers, rustic bookstalls, and a piecemeal national network. As yet unstudied, this infrastructure produced and circulated up to ten times the number of books as official, mainstream channels. A corpus of some five hundred of these cheap collections of recipes and techniques serves as the basis for this book. Judge focuses on four challenges common readers faced: how to cure an opium addiction, avoid an electric shock, prevent a cholera infection, and graft a plant. She further draws on government, archival, periodical, and fiction materials in devising composites of individual common readers so that we can better know them: details of the crises they faced, the remedies they tried, and the knowledge they relied on as they decocted cures and applied technologies. She argues that the acts of conciliation and assemblage these readers engaged in shaped the broader epistemic terrain from which historical change was actualized in China’s century of revolution.

Guts and Glory
From one of Australia's leading military historians and biographers, Peter Rees, comes Guts and Glory, an enthralling history of the way in which sport is ever present in the wars fought by, or involving, our Australian defence forces. The spirit of Australia can be seen so clearly in how we play and how we fight. From the famous cricket match played on the beach at Gallipoli as a decoy for the evacuation of Australian troops; to the hero of Tobruk, Changi and the Thai Burma railway, Colonel Sir Ernest Edward 'Weary' Dunlop AC, who so respected his hard-won Wallaby jersey, he insisted on being buried in it; to legendary Test cricketer Keith Miller, fighter pilot in WWII, who famously said 'Pressure is a Messerschmitt up your arse, playing cricket is not' - sport has always been part of our wars. A collection of vivid, moving, funny, powerful and poignant sporting stories from the wars fought by the Australian Defence Force ranging from WWI right through to the present day, Guts and Glory is a book about the way that sport is so often an intrinsic part of war; how sport provides a means for the diggers to cope with the pressures of the battlefield; how the lessons that we learn playing sport can be applied to the art of leadership and warfare; and how mateship and the Australian character and spirit can be seen in the way we fight and the way we play. 'This is ultimately an uplifting book, which celebrates the bonding and healing power of sport, in times of war and after it. For history buffs who can't miss Friday night footy or the Boxing Day Test, this is a book they'll devour.' Readings

Voices in Stone
Iconoclasm is in the air. Bitter debates rage in the press, through social media and on the streets around the proper fate of statues of controversial figures, whether slave traders, imperialists or Confederate generals. It is an important question, but discussion has largely been confined to the final act of the lives of statues. Paul Brummell''s contention is that statues should be understood through their changing roles during often complex lifetimes. Starting with a discussion of why sponsors and sculptors choose to erect figurative representations of human subjects, the book explores the impact of time on statues, as durable images in marble and bronze outlive the worldviews of their founders, becoming forgotten relics of past regimes or acquiring a toxicity when their subjects are identified as problematic by new generations. On this journey through the lives of statues, Brummell explores such issues as the circumstances under which statues move, talk, and even kill, the role of votive offerings and the vexed question of the rubbing of intimate bronze body parts, examining the stories of statues from ancient history to the present day, from the celebrated beauty of Praxiteles'' statue of Aphrodite at Knidos to the Romanian hero likened to a chubby Santa Claus.
Twilight of Camelot
From the author of the “insightful and well-crafted” (The Wall Street Journal) Kennedy and King comes a heart-wrenching and sensitive examination of the tragic loss of President John F. Kennedy and First Lady Jacqueline Kennedy’s premature son, Patrick, and how their shared grief brought them closer together in the months leading up to his assassination. In April 1963, the White House announced that Jackie was pregnant with a sibling for Caroline and John Jr.—joyful news after years of miscarriages and a stillbirth in 1956. But on August 7th, Patrick Bouvier Kennedy was born six weeks premature and died less than two days later. In this probing, soulful account of the struggle to save Patrick, Steven Levingston takes us inside the long-troubled relationship of Jack and Jackie as they faced one of the most difficult experiences of their marriage. With a “perceptive and eloquent” (The Christian Science Monitor) voice, Levingston reveals how Patrick’s death, tragic as it was, ultimately brought the couple closer together and set the President on a trajectory to be a better husband and father in the months leading up to their fateful campaign trip to Dallas. In a parallel storyline, Levingston reveals the largely unknown role President Kennedy played in modernizing an important corner of American health care. After Patrick’s death, he ordered studies into the primitive state of premature care and drummed up millions of dollars in government funding, igniting a revolution in treatments that over the decades have saved millions of infants thanks to the invention of baby ventilators, new drugs, and modern neonatal intensive care units. For his definitive account of Patrick’s brief but influential life, Levingston draws on first-ever interviews with doctors who treated Jackie and Patrick, in-depth revelations of the Secret Service agent in whose speeding car Jackie nearly gave birth prematurely, and on new archival documents. Twilight of Camelot is a fresh and humanizing portrait of one of the most famous and complicated couples of the 20th century, and a pulsating drama that illuminates one of the least-known periods in Kennedy family history.
Thomas More
Very Short Introductions: Brilliant, Sharp, Inspiring Thomas More is an enduringly fascinating and profoundly controversial figure.

This Very Short Introduction assesses More''s life, writings and achievements, and examines changing views of his character, in both historical interpretation and various works of fiction. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

Renaissance Polish Armies 1492–1569
This fully illustrated study assesses the armies of Poland at war in the first half of the 16th century, during the transition from feudal to standing forces. Against a background of almost continual warfare, the 80 years after 1492 witnessed the slow transformation of Polish forces from feudal levies to standing armies. The bloody struggle between Poles, Lithuanians, Hungarians, Muscovites, Cossacks, Turks and Tatars culminated in the Union of Lublin in 1569, uniting the Kingdom of Poland and the Grand Duchy of Lithuania. This crucial period in Polish military history saw the introduction and development of famous troop categories such as the Polish hussars, and a tactical transformation with the introduction of foot and mounted hand-gunners to replace crossbowmen. Drawing upon a wealth of sources, the author explains Polish armies' methods of recruitment; their organizational structure, and that of units of different troop categories; their weapons, armour and equipment; and their strategies and tactics. In this engaging book, specially commissioned artwork and rare illustrations combine with authoritative text to bring this under-researched subject to life for an English-language audience.
Mischlinge
A FORGOTTEN MANUSCRIPT. A FAMILY SECRET. AND THE URGENT NEED TO TELL THE WORLD ABOUT THE CHILDREN HITLER WANTED DEAD. THE TRUE STORY OF THE MISCHLINGE. Mischling (plural: Mischlinge): a cruel, derogatory term created by the Nazi regime to brand those of 'mixed blood'; children born to both Jewish and Aryan parents and grandparents. A word designed to degrade, divide and deny humanity. Berlin, 1935. A knock sounds at the Bernstein family's door. Eight-year-old Edie answers it to two Gestapo officials, who issue an unthinkable ultimatum; Edie's mother must divorce her Jewish husband – for the supposed 'protection' of her children. They hear the word Mischlinge for the first time. And from that moment on. it becomes a stain that seeps into every corner of their existence. Teachers and classmates gradually turn against Edie and her big brother Heini. Neighbours begin disappearing in the night. With each passing day, the circle tightens – until there is no safe place at home or on the streets. As antisemitic laws multiply and people around them disappear, Edie and Heini are dragged into a world of interrogation, surveillance and fear. Every knock at the door threatens separation. Every whisper risks arrest. Yet even as the Nazis close in, Edie and Heini refuse to let go of one another. 'Perhaps the most remarkable untold history of the Holocaust. Sharon Ring has done her mum proud with this brilliant – and utterly terrifying – story. A story so unlikely that it reads like a novel – yet every word is true.' – Rory Clements
America in the 21st Century
A sweeping political, economic, and social history of the United States from 2000 to 2025. America’s 21st century began with a bug—and nearly ended with another. Having survived the Y2k scare, the United States, having ended the Soviet Empire, expected to settle down into a period of quiet, if uninspiring, growth. What followed was anything but calm. After the 9/11 attacks, Americans were pulled inexorably into a pair of wars in the Middle East that saw President George W. Bush’s popularity go from nearly universal to nearly the worst in history. Bush’s presidency was finished off by the “Subprime Mortgage Crisis,” which in part enabled the rise of a young Barack Obama to the presidency. Instead of uniting America, Obama divided it further as Congress descended into years of futility while the American working class collapsed and American industry left. In 2016, Donald Trump ran on the platform of restoring the American dream, but was hamstrung by “resist” and “lawfare,” two relatively new political strategies that limited his achievements. A second “bug,” COVID-19, struck America in Trump’s final year, building enough dissatisfaction that, under questionable circumstances, Joe Biden was elected. A dissatisfied America boomeranged to make Trump only the second president in history to win an election, lose it, then win it again. Throughout, America’s economy, technology, and social structure changed in volcanic ways.
The Burning of the White House
It's unimaginable today, even for a generation that saw the Twin Towers fall and the Pentagon attacked. It's unimaginable because in 1814 enemies didn't fly overhead, they marched through the streets; and for 26 hours in August, the British enemy marched through Washington, D.C. and set fire to government buildings, including the U.S. Capitol and the White House. Relying on first-hand accounts, historian Jane Hampton Cook weaves together several different narratives to create a vivid, multidimensional account of the burning of Washington, including the escalation that led to it and the immediate aftermath. From James and Dolley Madison to the British admiral who ordered the White House set aflame, historical figures are brought to life through their experience of this unprecedented attack. The Burning of the White House is the story of a city invaded, a presidential family displaced, a nation humbled, and an American spirit that somehow remained unbroken.
Nagato-class Battleships 1920–46
An illustrated study of Japan’s Nagato-class battleships: the IJN’s powerful super-dreadnoughts, which were heavily modernized to fight in World War II. Illustrated with the author’s much-acclaimed 3D reconstructions, naval researcher Stefan Draminski offers a technical and operational study of Nagato and Mutsu, Japan’s most powerful battleships of the dreadnought era. They were the world’s first battleships to mount 16-inch guns, and signalled Japan’s determination to build a fleet that qualitatively outmatched the world’s leading navies. Entering service in the 1920s, they would be heavily modernized before the outbreak of the Pacific War, which Nagato would start as Yamamoto’s flagship for the Pearl Harbor attack. Both ships were present at the Battle of Midway, and though Mutsu would be sunk by a magazine explosion in 1943, Nagato fought at Philippine Sea and Leyte Gulf, before being modified again and moored at Yokosuka as an antiaircraft battery. The last Japanese battleship afloat on VJ-Day, Nagato was sunk in 1946 at Bikini Atoll in the Crossroads nuclear test. Drawing on Japanese-language sources and original documentation, this is a concisely detailed account of these formidable battleships, superbly illustrated with archive photos and artwork showing the ships through their careers and in action.
Canada in the Age of Rum
Awash in a sea of rum describes the years between the 1670s and the 1830s in the colonies that would later become Canada. Millions of litres of the sugar-based liquor were imported every year to supply a comparatively small population of colonists and Indigenous people. Why rum, and why so muc? um was cheap and plentiful. Intimately connected to the West Indian slave plantation complex, rum shipped to early Canada and around the Atlantic World was part of the early modern expansion of intercontinental trade known as the first globalization. Canada in the Age of Rum shows what happened to the vast quantities that came to Canadian shores. Rum was especially important to workers in the early Canadian staples industries. Fishermen and fur-trade voyageurs drank rum in massive quantities, supplied on credit and at grossly inflated prices by their employers, an arrangement that served to claw back wages and ensure the profitability of enterprises that would not have been viable otherwise. Traders deliberately sought to get hunting peoples hooked on rum in order to ensure a steady supply of pelts – alcohol was not so much a commodity for sale as it was a gift used to induce hunters to conform to the ways of the capitalist economy. However, Indigenous people drank rum in their own ways and for their own reasons; and when drinking became a serious social problem, they organized to resist it. The story ends in the 1830s when the combined effects of the temperance movement and the rise of whisky led to a sharp decline in rum consumption. This brilliant history follows the thread of a single commodity from West Indian plantations to Newfoundland, Quebec, and the west, revealing rum as a critical lubricant of the social life of early Canada and its particular version of early capitalism.
Hanns Eisler and His Circle in Republican Spain
Studies the development and impact of Hanns Eisler's music and Marxist activism in the tensions of 1930s Spain, revealing the interplay of varied influences, ideology and antifascist propaganda. Hanns Eisler in Republican Spain is the first comprehensive study to explore the political, artistic, and intellectual engagements of Hanns Eisler and his circle of Marxist musicians - including the singer Ernst Busch and the musicologist Otto Mayer-Serra - in relation to Spain between 1931 and 1939. The book reconstructs Eisler's collaborations with a broad range of Spanish antifascist organisations, examines the reception of his compositional and theoretical work in Republican Spain, and assesses the deep impact of the Spanish civil war on his vocal and symphonic music. It highlights the influence of key local, national, and international communist structures - notably the Unified Socialist Party of Catalonia (PSUC), the Communist Party of Spain (PCE), and the Comintern (Third International) - on the musical and political projects of Eisler and his circle. Grounded in detailed analysis of an extensive corpus of textual, musical, and press materials - primarily preserved in archives in Spain, Germany, Russia, France, and the United States - this study offers new critical frameworks for understanding the role of Western modernist music in contexts of ideological conflict and war. It provides a fresh perspective on the complex entanglements between antifascist propaganda and musical modernism in the interwar period. Hanns Eisler in Republican Spain makes a vital contribution to scholarship at the intersection of music, exile, propaganda, communism, and antifascism, and more broadly, to the study of how political ideologies shaped music, aesthetics, and musical thought across national boundaries during a pivotal era in twentieth-century European history.

The Point of the Needle
Tens of millions of people sew for necessity or pleasure every day, yet the craft is surprisingly under-appreciated. Now available in paperback, The Point of the Needle redresses the balance: this is a book that argues for sewing’s place in our lives. It celebrates not only sewing’s recent resurgence but sewists’ creativity, well-being and community. Barbara Burman chronicles new voices of people who sew today, by hand or machine, to explore what they sew, what motivates them, what they value and why they mend things, revealing insights into sewing’s more intimate stories. In our age of superfast fashion with its environmental and social injustices, this eloquent book makes a passionate case for identity, diversity, resilience and memory – what people create for themselves as they stitch and make.
