Imagine that you're swimming in the ocean and suddenly realize a baby gray whale is following you. This actually happened to Lynne Cox, and she wrote a book about the experience: Grayson. She describes that morning in the ocean: the confusion of figuring out what was in the water with her, the realization that the baby whale had lost his mother and if she didn't find a way to reunite them soon the baby may not make it, and her struggle to stay in the water with him. This beautifully descriptive book is definitely worth checking out!
