This was a fascinating look at Chicago in 1919. While the title states that this is about "12 days of Disaster" it seemed more like the whole year of 1919. There were many events in 1919 that changed Chicago forever; while most of these events do take place in the 12 days mentioned, I don't think that it was only those 12 days that mattered the most. Some of the events that took place I didn't know about prior to reading this book so it was nice to learn more about my hometown. I would recommend this book to Chicago natives and also to those interested in Chicago history.
