The book gives thorough, easy to follow walking tours throughout different areas of New York City. The historical facts and inclusion of details regarding the development of the city are impressive. The authors, Michele and James Nevius, are New York tour guides - I followed up with a tour of Greenwich Village with them to appreciate their level of knowledge of the area. If you are interested in a focused look at the city with insights into how time has passed through architecture and immigration, use this book as a guide.
