Seventeen-year-old long distance swimmer Lynne Cox was out training in the cold Pacific one morning when she became aware something was swimming beside her. It was an 18-foot baby gray whale that had apparently been following her for some time. Lynne realized that--much as she needed to swim to shore herself to rest--the calf would follow her, likely beach itself, and die. Even so, if the mother could not be found, the calf would starve. Something so enormous as a mother whale 50 feet long suddenly seemed very small in the vast Pacific. Grayson is the remarkable true story--part mystery, part magical tale--of Lynne's efforts to reunite mother and calf.
