President Obama’s former United States chief of protocol looks at why diplomacy and etiquette matter—from the international stage to everyday life. History often appears to consist of big gestures and dramatic shifts. But for every peace treaty signed, someone set the stage, using hidden influence to effect the outcome. In her roles as chief of protocol for President Barack Obama and social secretary to President Bill Clinton and First Lady Hillary Clinton, Capricia Penavic Marshall not only bore witness to history, she facilitated it. Sharing unvarnished anecdotes from her time in office, Marshall brings us a master class in soft power, unveiling the complexity of human interactions and making the case that etiquette, cultural IQ, and a flexible mind-set matter now more than ever. When the notion of basic civility seems to be endangered, Protocol reminds us how critical these principles are while providing an accessible guide for anyone who wants to be empowered by the tools of diplomacy in work and everyday life.
