Kevin Richardson is a guy who works with lions. He works in a lion park in South Africa and has pushed the limits of what was thought possible in interacting with lions and other predators. With the help of Tony Park, he tells the story of how he went from average kid to Lion Whisperer. It's a pretty good read, but not that well written. The story jumps about a little, and sometimes he forgets to finish a story. If you're interested in animal behavior, it's good enough from that point of view. He has some interesting insights into lion, hyena, and other predator behavior, as well as some good points about keeping animals in captivity.
