If you’re concerned about democracy and curious about comparisons to 1930s Germany, this worthwhile read follows America’s first ambassador to Nazi Germany and his family’s response—particularly his daughter, whose dalliances included the Gestapo chief and a Soviet spy—to the rise of Hitler. The result is a revealing, disturbing, and relevant depiction of moral complicity and political complexity and a dire warning about unexamined biases and underestimating evil.
