Black Beauty tells the story of a horse, from the horse's point of view, as he grows up and is sold from person to person. He is treated differently depending who is taking care of him, and is put to work doing different types of jobs. It is set (and was written) in the 19th century.
I read this when I was a kid, but really didn't remember it. Animal-lover that I am, of course, I really enjoyed it. I always enjoy animal books even more when they are told from the point of view of the animal, as there is an attempt to understand how that animal would feel and how they would react to things and why they might react the way they do. I was actually thinking this would be a good book for people who work with horses.
