I spent yesterday on a train (actually, several trains) listening for the first time to the audiobook of City. The narrator is Steven Crossley and he reads it beautifully. It's a new experience for me, listening to someone else read my words. I haven't heard all of it yet - it's more than thirteen hours long! - but I certainly enjoyed the experience. And I hope you will too. You can find it at Audible in the UK or the US.
City is still picking up reviews, most recently in the Spring 2013 issue of Urban Design journal, where it was described as "an excellent introduction to the city, and should be on every student's reading list".
