Good Reads aren't always light and happy. One that I read this summer was In the Garden of Beasts by Erik Lawson. His work is nearly always historical fiction. The first of his I read was called Isaac's Storm about the deadliest hurricane ever to hit Galveston. Next I read Devil in a White City which is the story of the building of the Chicago World's Fair along with the story of a physician/serial killer who was operating there at the same time. In the Garden of Beasts is the story of William Dodd, who becomes America’s first ambassador to Hitler’s Germany, and his family in 1933, a year that proved to be a turning point in history. It is informative, not uplifting but well told.
If you want to know more about America's response to these events. I recommend this one.
