This nonfiction book dovetails nicely with Erik Larson's Isaac's Storm about the 1900 Galveston hurricane. I suggest that if you are interested in hurricanes and the genesis of the National Weather Service, read Larson's book first.
The instant book, as the title states, is about the Category 5 hurricane that decimated the lower keys in Florida on Labor Day in 1935. Comparing the two books, it is interesting to see how weather forecasting was still more of an art than a science 35 years after the category 4 hurricane devastated Galveston. Knowles is not the adroit writer that Larson is, but the book is replete with meticulous research and is still an interesting read. The main character, of course, is the hurricane, but the stories of multiple victims track the chronology and path of the violent storm. One of the surprise characters who pops up in the book is Ernest Hemingway himself, who lived on the relatively unscathed Key West and helped with rescue and recovery efforts after the storm passed. Reading this book will definitely make you appreciate the Weather Channel and all of the available weather apps that keep you in the know and provide advance warnings.
