Chafetz cleverly uses Detroit's famous "Devil's Night" as a moniker, a night when the city folk actually burn down their own neighborhoods for fun. I grew up going through many a Devil's Nights, so I have seen firsthand the level of sickness inherent in this ritual. Chavetz does some interesting interviews, though his thoroughness is lacking, and I see that he really doesn't get a good grip on the root of the city's problems, that being corruption, affirmative action, divisiveness toward the suburbs, and tax policies that drive away those that might otherwise be Detroit residents.
Detroit is a poster child for the effects upon a spontaneous order at the hand of racially divisive power grabs and coercive political machinations, but I wouldn't count on Chavetz to give a scholarly and accurate view of that. The book is interesting, slightly sensationalized, and never scholarly, but overall, it is a decent overview on the problems of Detroit.
