Reading: Devil in the White City-part 2

Ok, so in four hours I was able to read about 50 pages, but this book is dense. I am really intrigued at the knowledge of architecture and landscaping that the author had to obtain in order to write this book effectively. Yet, he writes it in a way that I can actually understand and appreciate and don't want to merely gloss over. Overall, I'm still into the book, which is pretty impressive, as I usually tend to like books that have a love story, a female protagonist or espouses some philosophy. This book does none of those! Perhaps, I am maturing a bit?
