Overall, I thought this was fine. It's a solid 3.5 read for me, rounded up.

I was anticipating that the serial killer aspects of the story to be more interesting, but I found myself way more interested in The World's Fair aspects. I thought these two stories did not mesh well. Though the book promotes them as working together, they hardly do. Besides them happening at the same time and in the same general area, they're completely unrelated.

I was blown away that The World's Fair happened at all! There's not a single thing that went as planned and yet they still put it on with great success! I kept waiting for it all to collapse, and it never did. This is what kept me engaged with the story.

I would recommend this book. Larson has a way of telling history that feels like fiction, which was exciting!
