A groundbreaking narrative a historical political thriller that explores the role of the Sons of Liberty in the American Revolution.More than two hundred years ago, a group of British colonists in America decided that the conditions under which they were governed had become intolerable. Angry and frustrated that King George III and the British Parliament had ignored their lawful complaints and petitions, they decided to take action.Knowing that their deeds often directed at individuals and property were illegal, and punishable by imprisonment and even death, these agitators plotted and conducted their missions in secret to protect their identities as well as the identities of those who supported them. Calling themselves the Sons of Liberty, they gathered together in a radical society committed to imposing forcible change. Those determined men including second cousins Samuel and John Adams, Paul Revere, Patrick Henry, and John Hancock saw themselves as patriots. Yet to the Crown, and to many of the Sons' fellow colonists, the revolutionaries were terrorists who deserved death for their treason.In this gripping narrative, Les Standiford reveals how this group of intelligent, committed men, motivated by economics and political belief, began a careful campaign of interlocking events that would channel feelings of vague injustice into an armed rebellion of common cause, which would defeat an empire and give birth to a radical political experiment a new nation known as the United States.

Confidence. We want it. We need it. But it can be maddeningly enigmatic and out of reach. The authors of the New York Times bestseller Womenomics deconstruct this essential, elusive, and misunderstood quality and offer a blueprint for bringing more of it into our lives.Is confidence hardwired into the DNA of a lucky few or can anyone learn itIs it best expressed by bravado, or is there another way to show confidenceWhich is more important: confidence or competenceWhy do so many women, even the most successful, struggle with feelings of self-doubtIs there a secret to channeling our inner confidenceIn The Confidence Code, journalists Katty Kay and Claire Shipman travel to the frontiers of neuroscience on a hunt for the confidence gene and reveal surprising new research on its roots in our brains. They visit the world's leading psychologists who explain how we can all chose to become more confident simply by taking action and courting risk, and how those actions change our physical wiring. They interview women leaders from the worlds of politics, sports, the military, and the arts to learn how they have tapped into this elemental resource. They examine how a lack of confidence impacts our leadership, success, and fulfillment.Ultimately, they argue, while confidence is partly influenced by genetics, it is not a fixed psychological state. That's the good news. You won't discover it by thinking positive thoughts or by telling yourself (or your children) that you are perfect as you are. You also won't find it by simply squaring your shoulders and faking it. But it does require a choice: less people pleasing and perfectionism and more action, risk taking, and fast failure.Inspiring, insightful, and persuasive, The Confidence Code shows that by acting on our best instincts and by daring to be authentic, women can feel the transformative power of a life on confidence.

Why do some workplace cultures inspire energy and innovation, while others fuel anxiety, boredom, or cynicismUntil now, such legendary cultures have seemed like magic beyond our control. However, behind every culture is a surprisingly elegant science. Primed to Perform proves that the highest-performing cultures are built on a simple truth: why people work affects how well they work. Great organizations inspire the three most powerful motives for work play, purpose, and potential and eliminate the three most destructive emotional pressure, economic pressure, and inertia. They create total motivation (or ToMo, for short). Total motivation cultures create the highest-performing employees and the most adaptive organizations.Authors Neel Doshi and Lindsay McGregor show that extraordinary performance at companies like Southwest Airlines, Starbucks, Apple, and Whole Foods comes from cultures that inspire total motivation. They describe how investment professionals, salespeople, teachers, and CEOs perform better when driven by total motivation. And, most important, they share how you can build a culture that inspires total motivation in every moment of every day.Primed to Perform builds on over a century of academic thinking as well as the authors' original research into how ToMo drives performance at iconic companies. It introduces the authors' highly predictive new measurement tool, the total motivation factor, which allows leaders to measure the strength of their culture and understand how it changes over time. It gives leaders the tools to transform their own workplaces.High-performing cultures can't be left to chance; organizations must create systems that shape and maintain them. Whether you're a five-person team or a start-up, an elementary school or a university, a nonprofit or a mega-institution, Primed to Perform shows you how.

A saga bursting with love affairs, class divisions, cultural clashes, ambition, betrayals, and secrets, Mr. Selfridge is set in an era when women reveled in a new sense of freedom and modernity. A charming, dynamic, brilliant, and forceful man who enjoys and respects women, Harry opens the doors of his opulent department story on London's famed Oxford Street to indulge, empower and celebrate them, changing the way the British—and the world—shopped forever.

A behind-the-scenes look at the hugely popular and often controversial world of women's tennis featuring such household names as Venus and Serena Williams and Anna Kournikova. At a time when attendance and TV ratings for women's tennis are at an all-time high, Sports Illustrated writer L.Jon Wertheim, draws on his investigative talents and knowledge of the game to infiltrate the heretofore closed locker rooms of the women's tour and chronicle this remarkable era in the sport's history. With a narrative sweep that rockets along like a Venus Williams serve, it takes the reader from the year's first Grand Slam tournament--where a top player ignited a firestorm of controversy when she decided to come out-- to Venus' epochal victory at Wimbledon to the U.S. Open where Serena Williams defends her title and all the whistle-stop tournaments in between where the Russian vixen Anna Kournikova sent hormonally challenged teenagers, not to mention male sportswriters, into a frenzy, Venus Envy offers the reader the equivalent of a center-court seat and an all-access locker room pass. The book will contain a wealth of previously unreported, inside-the-locker room anecdotes about the marquee names in women's tennis and should engender much off-the-book-page coverage. There are more identifiable stars than ever before and the rivalries are intense and often rancorous. The book will even appeal to those readers with only a passing interest in tennis since many of the players have transcended the sport, appearing on the covers of magazine like GQ, Rolling Stone and Vogue.

From the author of the bestselling Dorothy Dandridge comes a dazzling look at one of America's brightest and most troubled theatrical stars. Almost no other star of the twentieth century reimagined herself with such audacity and durable talent as did Ethel Waters. In this enlightening and engaging biography, Donald Bogle resurrects this astonishing woman from the annals of history, shedding new light on the tumultuous twists and turns of her seven-decade career, which began in Black vaudeville and reached new heights in the steamy nightclubs of 1920s Harlem. Bogle traces Waters' life from her poverty-stricken childhood to her rise in show business; her career as one of the early blues and pop singers, with such hits as "Am I Blue?," "Stormy Weather," and "Heat Wave"; her success as an actress, appearing in such films and plays as The Member of the Wedding and Mamba's Daughters; and through her lonely, painful final years. He illuminates Waters' turbulent private life, including her complicated feelings toward her mother and various lovers; her heated and sometimes well-known feuds with such entertainers as Josephine Baker, Billie Holiday, and Lena Horne; and her tangled relationships with such legends as Irving Berlin, Duke Ellington, Harold Clurman, Elia Kazan, Count Basie, Darryl F. Zanuck, Vincente Minnelli, Fred Zinnemann, Moss Hart, and John Ford.In addition, Bogle explores the ongoing racial battles, growing paranoia, and midlife religious conversion of this bold, brash, wildly talented woman while examining the significance of her highly publicized life to audiences unaccustomed to the travails of a larger-than-life African American woman.Wonderfully atmospheric, richly detailed, and drawn from an array of candid interviews, Heat Wave vividly brings to life a major cultural figure of the twentieth century a charismatic, complex, and compelling woman, both tragic and triumphant.
