Grayson by Lynne Cox
A true story. Lynne Cox swims in the ocean every day in early morning hours, training for various long-stretch swim endeavors such as swimming the English Channel. One day she feels that something is swimming underneath her, but she is not sure, and if it is something, she doesn't know what it is. Instinct tells her to keep swimming and not to fear. Eventually she discovers it is a baby gray whale. This is her story of swimming with the whale, hoping it can be reunited with its mother. As time passes she experiences close sightings of many other ocean and sky creatures. I can't imagine what an almost mystical experience that must have been.
