The Devil's Teeth by Susan Casey
It started with watching a documentary during a bout with mononucleosis, and turned into a drive to learn and experience great white sharks. Just off the coast of California, near San Francisco, some of the largest white sharks in the world congregate, migrating there year after year. Susan Casey managed to get a day pass to visit the biologists living on the Farallone Islands, a remote research occupied by a few scientists each year. With the sighting of her first great white, she was hooked to the point of obsession, and had to return. She examines the history of the sharks and the island, learning as much as she could while there.
While reading this book, you get a sense of the obsession that Casey felt while studying the sharks. The power, intelligence, and character of the sharks inspired her, and in turn Casey inspires you. Although the general feeling I got from the book was of the necessity to study and protect our oceans, the book was not written as a guilt trip. The emotion is genuine, coming from Casey's absolute love for the animal.
