One of seven touching true stories from Wish You Were Here!, the tale of Butlin’s holiday camps. ‘When I got to the camp I felt as if I’d suddenly walked into Utopia – it was so colourful, so warm, so friendly. There were lights across the roads, there were banners fluttering in the breeze… There seemed to be laughter coming from every building.’ With grey post-WWII skies hanging low over Britain, factories lining the streets and smoke stacks dotting the horizon, there was one way that ordinary families could escape: the ever-cheerful holiday camps of Butlin’s. When Billy Butlin founded his holiday camps in 1936, they were bastions of community spirit and havens of luxury. Here, for one week, wives and mothers were freed from the toil and drudgery of housework, children ran free through the grounds, fathers and husbands hung up their work clothes. Ever-helpful redcoats were on hand all hours of the day, dinner halls ready with plentiful food for old and young alike, bars stocked to quench any level of thirst, ballrooms waiting to be flooded with shiny shoes, rustling dresses and peals of laughter. And, as the sun went down on another exhausting, happy day, a chorus line was ready to sing holidaymakers back to their beds. Rich in period detail and highly evocative, Wish You Were Here! follows the lives of seven of the camps’ key figures through the highs and lows of the holiday season: from redcoats searching for stardom to young families who returned year after year, to pensioners who rediscovered an inner youth. The laughter and tears, the loves and losses, and the fun and friendships that have lasted a lifetime – it's all here. Funny, moving and heartwarming, they are tales of swimming pools and sing-a-longs, Glamorous Grannies and bicycle rides, and of a community spirit that burned brightly in a much-loved British institution.

The story of Britain’s colourful maritime past seen through the changing fortunes of the Cornish port of Falmouth. Within the space of few years, during the 1560s and 1570s, a maritime revolution took place in England that would contribute more than anything to the transformation of the country from a small rebel state on the fringes of Europe into a world power. Until then, it was said, there was only one Englishman capable of sailing across the Atlantic. Yet within ten years an English ship with an English crew was circumnavigating the world. At the same time in Cornwall, in the Fal estuary, just a single building – a lime kiln – existed where the port of Falmouth would emerge. Yet by the end of the eighteenth century, Falmouth would be one of the busiest harbours in the world. ‘The Levelling Sea’ uses the story of Falmouth’s spectacular rise and fall to explore wider questions about the sea and its place in history and imagination. Drawing on his own deep connection with Cornwall, award-winning author Philip Marsden writes unforgettably about the power of the sea and its ability to produce greed on a piratical scale, dizzying corruption, and grand and tragic aspirations.

A high-octane account by a decorated major in the British Army of his high-level dealings with the Bosnian Serb leadership, of his running a ‘Schindler’s List’ operation in Sarajevo, and of his extraordinary subsequent arrest by Ministry of Defence police on suspicion of betraying secrets to the Serbs. Trusted Mole is the powerful and disturbing first-hand account of a British soldier of part Yugoslav origin painfully caught up in the savage maelstrom of the Bosnian war. Armed only with the pseudonym ‘Mike Stanley’ and an antiquated Serbo-Croat vocabulary, Milos Stankovic – an officer in the Parachute Regiment – worked as interpreter and go-between for two British brigadiers and two British UN generals, Mike Rose and Rupert Smith. His experiences plunged him deeper and deeper into Bosnia’s heart of darkness, where all human life was lived in extremis. His own Balkan heritage likewise drew him in: his Scottish grandmother had been a nurse on the Salonika front in the First World War; his father was a former Royalist Yugoslav who had fought in the Second World War; and his mother in 1945 had driven one of the first UN ambulances around Bosnia and Montenegro. In helping to negotiate ceasefires between rival warlords, securing the release of UN hostages and organising the escape from Sarajevo of stricken families, Milos Stankovic was propelled from one nerve-wracking crisis to another. Throughout he was engaged in the highly dangerous game of bridging the gap between alien Balkan and Western mentalities. His was a role for which there was no military rule-book, and in the general climate of suspicion and paranoia his close contacts with the Bosnian Serb leadership of Dr Karadzic and General Ratko Mladic caused him to be branded by the Americans and the Bosnian Muslims as a Serb spy in the UN and later as a British spy – General Rose’s ‘trusted mole’. In a final, horrific twist, the author was arrested by the British authorities on suspicion of being a Serb spy. At journey’s end, Milos Stankovic was now confronted with the awful and inescapable truth of ‘Mike Stanley’.

This is Lilian’s story, one of four stories from The Sugar Girls. During the Blitz and the years of rationing, the Sugar Girls kept Britain sweet. The work was back-breakingly hard, but the Tate & Lyle factory was more than just a workplace - it was a community, a calling, a place of love and support and an uproarious, tribal part of East London. ‘When Lilian Tull came to Tate & Lyle shortly after the end of the war, she was older than most new arrivals. A lanky, fairhaired woman of 23, she worked in the can-making department, where the Golden Syrup tins were assembled. Lilian had arrived on the job with a heavy heart, and her colleagues noticed a sad, far-away look in her eyes.’ In the years leading up to and after the Second World War thousands of women left school at fourteen to work in the bustling factories of London’s East End. Despite long hours, hard and often hazardous work, factory life afforded exciting opportunities for independence, friendship and romance. Of all the factories that lined the docks, it was at Tate & Lyle’s where you could earn the most generous wages and enjoy the best social life, and it was here where The Sugar Girls worked. This is an evocative, moving story of hunger, hardship and happiness, providing a moving insight into a lost way of life, as well as a timeless testament to the experience of being young and female. Includes Lilian’s own personal photographs of life as a sugar girl.

From best-selling author of Tail-End Charlie and Tornado Down comes this powerful and deeply moving account of Bomber Command’s 1944 Nuremberg Raid – the RAF’s bloodiest night of the Second World War More men from Royal Air Force Bomber Command died on one single night of the Second World War than the total RAF aircrew losses during the whole of the four-month-long Battle of Britain. This is the story of the air raid intended to be the climax of Sir Arthur ‘Bomber’ Harris’s relentless campaign to defeat Nazi Germany. The target was Nuremberg: 795 aircraft set out, nearly 700 men did not return. In ‘The Red Line’, we meet the young aircrew who flew on the night of 30 March 1944. John Nichol has interviewed the few surviving veterans, British and German, in the air and on the ground, to record the voices of a diminishing generation. While the airmen of Bomber Command were among the greatest heroes of the conflict, their contribution and sacrifice has been sidelined in the face of post-war criticism of Bomber Command’s tactics. John Nichol’s dramatic tribute to the men who flew on the RAF’s bloodiest raid has provided the surviving veterans with the chance to tell the story of that terrible night – the night they flew to Nuremberg.

New York Times Bestseller THE EPIC TRUE STORY OF DUNKIRK NOW A MAJOR MOTION PICTURE, WRITTEN AND DIRECTED BY CHRISTOPHER NOLAN, AND STARRING KENNETH BRANAGH, TOM HARDY, AND MARK RYLANCE The Battle of Dunkirk, in May/June 1940, is remembered as a stunning defeat, yet a major victory as well. The Nazis had beaten back the Allies and pushed them across France to the northern port of Dunkirk. In the ultimate race against time, more than 300,000 Allied soldiers were daringly evacuated across the Channel. This moment of German aggression was used by Winston Churchill as a call to Franklin Roosevelt to enter the war. Now, historian Levine explores the real lives of those soldiers, bombed and strafed on the beaches for days on end, without food or ammunition; the civilians whose boats were overloaded; the airmen who risked their lives to buy their companions on the ground precious time; and those who did not escape.

‘Trees are wildlife just as deer or primroses are wildlife. Each species has its own agenda and its own interactions with human activities …’ Written by one of Britain’s best-known naturalists, Woodlands offers a fascinating new insight into the trees of the British landscape that have filled us with awe and inspiration throughout the centuries. Looking at such diverse evidence as the woods used in buildings and ships, and how woodland has been portrayed in pictures and photographs, Rackham traces British woodland through the ages, from the evolution of wildwood, through man’s effect on the landscape, modern forestry and its legacy, and recent conservation efforts and their effects. In his lively and thoroughly engaging style, Rackham explores woodlands and their history, through names, surveys, mapping and legal documents, archaeology, photographs and works of art, thus offering an utterly compelling insight into British woodlands and how they have come to shape a national obsession.

Earth is our Business takes forward the argument of Polly Higgins’ first book, Eradicating Ecocide. This book proposes new Earth law, but it is also about something more than law: it advocates a new form of leadership which places the health and well-being of people and planet first. Polly Higgins shows how law can provide the tools and be a bridge to a new way of doing business. She argues, in fact, that Earth is the business of us all, not the exclusive preserve of the executives of the world’s top corporations. Expanding on the proposal in her first book to make Ecocide an international crime, this book sets out the institutional framework for sustainable development and international environmental governance. It proposes new rules of the game to transform our economies, energy supplies and political landscape in a radical, but practical, way. The implications of Polly Higgins’ proposal are far-reaching and profound. Like her award-winning first book, Earth is our Business is written for anyone who is engaging in the new and emerging discourse about the future of our planet and sustainable development. Instead of merely examining the problem, Earth is our Business sets out a solution: new rules of the game. They are, says Polly Higgins, a new set of laws based on the sacredness of all life. Included as appendices are a draft Ecocide Act, a proposal for revising World Bank investment rules, and the indictment used in the mock Ecocide Trial held in the UK Supreme Court in September 2011.

Build real-world, industry-strength data storage solutions with time-tested design methodologies using CassandraAbout This BookExplore design patterns which co-exist with legacy data stores, migration from RDBMS, and caching technologies with CassandraLearn about design patterns and use Cassandra to provide consistency, availability, and partition tolerance guarantees for applicationsHandle temporal data for analytical purposes Who This Book Is For This book is intended for big data developers who are familiar with the basics of Cassandra and wish to understand and utilize Cassandra design patterns to develop real-world big data solutions. Prior knowledge of RDBMS solutions is assumed.What You Will LearnEnable Cassandra to co-exist with RDBMS and other legacy data storesExplore various design patterns to build effective and robust storage solutionsMigrate from RDBMS-based data stores and caching solutions to CassandraUnderstand the behaviour of Cassandra when trying to balance the needs of consistency, availability, and partition toleranceDeal with time stamps related to data effectivelySee how Cassandra can be used in analytical use casesApply the design patterns covered in this book in real-world use cases In Detail There are many NoSQL data stores used by big data applications. Cassandra is one of the most widely used NoSQL data stores that is frequently used by a huge number of heavy duty Internet-scale applications. Unlike the RDBMS world, the NoSQL landscape is very diverse and there is no one way to model data stores. This mandates the need to have good solutions to commonly seen data store design problems. Cassandra addresses such common problems simply. If you are new to Cassandra but well-versed in RDBMS modeling and design, then it is natural to model data in the same way in Cassandra, resulting in poorly performing applications and losing the real purpose of Cassandra. If you want to learn to make the most of Cassandra, this book is for you. This book starts with strategies to integrate Cassandra with other legacy data stores and progresses to the ways in which a migration from RDBMS to Cassandra can be accomplished. The journey continues with ideas to migrate data from cache solutions to Cassandra. With this, the stage is set and the book moves on to some of the most commonly seen problems in applications when dealing with consistency, availability, and partition tolerance guarantees. Cassandra is exceptionally good at dealing with temporal data and patterns such as the time-series pattern and log pattern, which are covered next. Many NoSQL data stores fail miserably when a huge amount of data is read for analytical purposes, but Cassandra is different in this regard. Keeping analytical needs in mind, you’ll walk through different and interesting design patterns. No theoretical discussions are complete without a good set of use cases to which the knowledge gained can be applied, so the book concludes with a set of use cases you can apply the patterns you’ve learned.Style and approach This book is written in very simple language and an engaging style complete with examples in every chapter and real-world use cases at the end of the book.
