NEW YORK TIMES BESTSELLER • Inspired by a profound experience swimming with wild dolphins off the coast of Maui, the bestselling author of The Wave set out on a quest to learn everything she could about dolphins—the other intelligent life on the planet. “Part science, part memoir, part impassioned plea for change.” —People  Susan Casey’s journey takes her from a community in Hawaii known as “Dolphinville,” where the animals are seen as the key to spiritual enlightenment, to the dark side of the human-cetacean relationship at marine parks and dolphin-hunting grounds in Japan and the Solomon Islands, to the island of Crete, where the Minoan civilization lived in harmony with dolphins, providing a millennia-old example of a more enlightened coexistence with the natural world.   Along the way, Casey recounts the history of dolphin research and introduces us to the leading marine scientists and activists who have made it their life’s work to increase humans’ understanding and appreciation of the wonder of dolphins.
