Started in Spring 2012; finished in Spring 2013. I set this aside for most of a year before picking it up again. It's a very good history of the changing landscape of Boston; it's just rather large and ponderous, and the final chapters are tacked on as the author updated it every 10 years or so. He likes City Hall! Appalling.
