A World Underground: The New York City Subway Variety Book is a humorous and informative book with unique and all-too-familiar true stories, fun facts, and subway history. New York City has 8.5 million people. It is the city that never sleeps. That means there are at least 8.5 million stories. With such diversity, squeezing all of these people into a cramped subway car can lead to interesting moments. But what sets people apart also brings them together. Stories range from acts of kindness to insane things that can happen beneath the rock. Did you know that Jay-Z was named after the J/Z subway line? Have you ever ridden through the closed 6 train stained glass station? Do you know what "sick passenger" really means?
