If You're Going to Read 1 Urbanist Book, Do This One
I'm actually updating my rating, which was a 4/5 originally. I still think about and reference this book regularly, so I think it deserves that 5.
The tenth anniversary of this book is a must. The original is good, but it lacks any analysis of race. The tenth anniversary filled in a lot of these gaps, as well as reckoning with societal and tech changes since original publication.
To date this is the single most informative and comprehensive urbanist book I know, while still being very easy to read. It's not perfect, but it's the best place to start.
