Book excerpt: In this memorable first book, Behind the Dolphin Smile, Richard O'Barry told the inspiring story of his personal transformation from world-famous dolphin trainer (Flipper was his pupil) to dolphin liberator. Now, in To Free a Dolphin, he passionately recounts the dramatic story of his heart-breaking campaign to release captive dolphins back into the wild. With wit and insight he chronicles the extreme opposition he has faced from bureaucrats, major players in the captive-dolphin industry, rival wildlife groups, and well-meaning sentimentalists. He introduces readers to famous show animals he has helped, including Bogie and Bacall of Key Largo. And, most fascinating, he describes his struggles to deprogram and rehabilitate dolphins emotionally scarred from years of captivity--struggles that become battles for the animals' souls.
