McCann chooses to describe one day in the life of New York City, the day in 1974 that the aerialist walked between the not-quite-finished Twin Towers. The chasm between rich and poor, the joy of connection, and the inevitability of our mortality are told through the lives of six different New Yorkers, including that incredible man dancing on that thin wire who epitomizes joy and triumph, if only for a short and precarious time. If you love New York, you’ve got to read this book. If you love the human journey towards the possible, you’ve got to read this book.
