In The Garden Of Beasts by Erik Larson

Set in 1930s Berlin, the narrative follows William E. Dodd, the first American ambassador to Nazi Germany, and his family as they navigate the increasingly oppressive and dangerous political landscape under Hitler's regime. Through their eyes, the story captures the gradual escalation of tyranny and anti-Semitism, highlighting the initial global underestimation of the Nazi threat. As Dodd becomes more aware of the brutal realities and the world teeters on the brink of war, the book paints a vivid picture of a society in moral decline and the personal and political challenges faced by those who witness history unfolding.
