The Devil in White City

After finally finishing The Devil in White City this afternoon on the subway ride home, I wondered why this book is such a huge bestseller.  It's been on the NY Times bestseller list for years!!  I don't get it.  I found it long and tedious and I struggled to finish it.  I guess there are a lot of people out there who are interested in reading about Chicago architecture and the Chicago World's Fair.  I love Chicago, but I don't have the patience to read paragraph after paragraph about building construction, fair attendance, and groundskeeping issues.
