20 Minutes In Manhattan is a wonderful portrayal of, literally, a twenty minute walk to work in Manhattan. Author Michael Sortkin spends several chapters just describing and dissecting the surroundings, such as chapter 1 is titled "THE STEPS" and chapter 2 "THE SIDEWALK" and so on.
While this methodical description of mundane activities may sound boring and dry, it is in fact a very interesting book. Instead of just describing, step by step the walk, Sortkin uses the walk to reflect on urban life and appearance. The book is sprinkled with anecdotes and witty observations.
Sortkin also uses the book to talk about architecture. Cast Iron Buildings, low-rises, high-rises, and he never misses the details.
Overall, the book is a great read, particularly for if you like architecture and urbanism. The book is especially relevant if you live (or lived) in NYC, or any big city for that matter. I recommend this for 7th or 8th graders, because 6th graders might find it dull.
