Black Beauty begins with a young horse's carefree days as a colt on an English farm with his mother, to his difficult life pulling cabs in London, to his happy retirement in the country. Along the way, he meets with many hardships and recounts many tales of cruelty and kindness. Each short chapter recounts an incident in Black Beauty's life containing a lesson or moral typically related to the kindness, sympathy, and understanding of horses. While forthrightly teaching animal welfare, Black Beauty also teaches how to treat people with kindness, sympathy, and respect. The novel became an immediate best-seller, with Sewell dying just five months after its publication, but having lived long enough to see her only novel become a success. With fifty million copies sold, Black Beauty is one of the best-selling books of all time.
