I bought this book because I love Erik Larson and his other works. This book talks about the 1893 World's Fair, which was very interesting. I learned a lot about the exhibitions and hassles that went into putting a World's Fair together. I have never been to a World's Fair, and this book made me want to go. As an added bonus, this book featured serial killer H. H. Holmes, and noted how he used the World's Fair to find victims. This book was mention on the reading list for The Last Podcast On The Left (Episodes 200-202). Holmes was one of the first recognized serial killers of modern times, and claimed to have killed nearly thirty people. He was only legally responsible for seven murders. I like reading about these historical crimes, and I thought the connection between such a well known serial killer and another major historical event was very interesting. There were a lot of complaints about the back and forth between the two subjects, but that didn't bother me at all. I thought the book was very good.
