I always loved taking the subway in New York City— it's home to so many people that you wouldn't get to interact with any other way. It is filled with the unique lives of strangers you might never meet again. The subway is also filled with deeply personal, intimate moments— it is a place for tears, emotional outbursts, eavesdropping, and my very favorite, people watching. This book is full of closely observed portraits of people who take the subway every day. Between sunrise and sunset, it welcomes and farewells people, and holds them—along with their joys, hopes, fears, and memories—in its embrace.
