Dawidoff, who grew up in New Haven and returned to live there in middle age, has written a great American book. But I was 226 pages in, just over halfway, when I realized how great it was shaping up to be. The book takes a long time to go from 0 to 65. It’s bigger than it has to be, and it’s not a model of elegant design; it reminds me of my clunky 2004 minivan, roomy and comfy, with poor steering and iffy brakes, always a little out of control. But then again, I love my minivan.
