I was pleasantly surprised by this book. I'd been expecting (and dreading) a subjective rant on suburbia in the sensationalist style of, say, Eric Schlosser. Instead, what I got was a mostly-straightforward, textbooky-but-conversational account of the anatomy of sprawl, the policies that helped create it, and the negative externalities associated with suburban lifestyles. The second half describes how to rekindle the construction of more sensible urban forms and gives clear descriptions of just what those forms are. I'd even venture the phrase, "definitive text."
