The story of a crucible, a period bounded by two shocks to America's psyche, two assaults on the country's sense of itself: the attacks of September 11 in 2001 and the storming of the US Capitol on January 6, 2021. Following the lives of everyday Americans in three cities across two decades, Osnos illuminates the country in a startling light, revealing how it lost the moral confidence to see itself as larger than the sum of its parts.
