In 1996, Francisco "Pipín" Ferreras, a native Cuban and a world champion in the dangerous and controversial sport of free diving, met Audrey Mestre, a beautiful French marine biology student. A passionate romance immediately bloomed between the two, and their love was bonded by a shared fascination with and devotion to the ocean. They soon became free diving's power couple, testing the limits of their wills and bodies by descending to unthinkable depths. Then, on October 12, 2002, in a dive off the coast of the Dominican Republic, tragedy struck: Audrey's attempt to break the world record of 170 meters ended in her death. Now, for the first time, Pipín tells his story. He shares the heart-pounding adventure and fierce competition that fuel the sport of free diving and his own addiction to it. He addresses the controversy that has followed him throughout his career and that spun out of control after Audrey's death. And he relates the haunting story of his relationship with Audrey -- a unique and complicated tale of love and obsession taken to extreme depths.
