I picked this book up off my parents' bookshelf, thinking that it was some hipster ironic garbage. A few pages in, I checked the author's credentials.. turns out he writes for the NY Times, and has been covering the subway system in NYC for years.
So, looking past the horrible title and weak cover image, I dug deeper into the book. It is clearly written by a fan of the underground rail system, and every character, bizarre legend, and uplifting anecdote show a world that not only is reflective of New York City, but one that helps shape it.
If you're a fan of the decrepit walls and the occasional rat, or the Michael Jackson midget impersonator at Grand Central Station, pick this up. It's about so much more than just the lines, or the obsessives and street performers. Also, as it is incredibly well-written, it'll even bulk up that vocabulary, helping you get a job and an excuse to ride the subway!
