The 2010s marked a shift in America’s trajectory, beginning with the run-up to Donald Trump’s election, through to the chaos and confusion left in its wake. With the wit and verve that has made her the acclaimed national historian of a generation, Jill Lepore reflects on the consuming fissures of this era: culture wars and media corrosion; disruptive innovation and techno-utopianism; constitutional crises surrounding gun rights and a reckoning with a deep history of racial violence. These essays make sense of American life in a moment of polarization, capturing the tumultuous relationship between the country’s violent past and fractured present.
