This book is definitely a puzzle. It sort of turns everything on its head. Even if you think you know American/Ohioan history, the information presented in this book will make you wonder if you're missing something. There are layers of confusion and uncertainty in here. I really enjoyed reading it, piecing things together, and then looking into it afterwards, to find out how much of it was true.
Some of the characterization did feel flat to me and the narrator's conceit didn't really work all that well; he's totally transparent. But it's definitely a good thinking book.
