The first definitive exploration of the role of the twenty-first century First Lady, painting a comprehensive portrait of Jill Biden and the evolution of the First Lady's role from ceremonial figurehead to political operative-from a White House correspondent for The New York Times. Since the Clinton era, tectonic shifts in media, politics, and pop culture have all redefined expectations of First Ladies, even as the boundaries set upon them have at times remained frustratingly anachronistic. With sharp insights and dozens of firsthand interviews with major players in the Biden, Obama, Trump, Bush, and Clinton orbits, including Jill Biden and Hillary Clinton, New York Times White House correspondent Katie Rogers traces, from the dawn of the twenty-first century, the evolution of the role of First Lady into a modern power broker with the potential to deliver on behalf of the president, while also painting a full portrait of Jill Biden.
