In the 1970s, Diana Nyad was widely regarded as the greatest long-distance swimmer in the world and set many world records, such as circling Manhattan Island and crossing the 102.5 miles between the Bahamas and Florida. But one record continually eluded her: becoming the first woman to swim between Cuba and the Florida Keys without a shark cage. Finally, in September 2013, after four failed attempts and at the age of 64, Diana completed the crossing after two days and two nights of continuous swimming - 53 consecutive hours, 110 miles. Millions of people watched her and cried and cheered and were dazzled and amazed by her tenacity and courage. This memoir is a dramatic, page turning account of the epic endurance quest that led to that moment, and is also a galvanizing call to live life boldly with no regrets.
