"Aesop's Fables" by Aesop
Aesop lived in Ancient Greece, 500 or more years before Christ. He was supposedly a slave, possibly deformed, and there is anecdotal evidence that he was condemned to death by the Oracle of Delphi. Long after his death, his stories - many of which were not even written by him, and didn't even originate in Greece - were collected into the group of tales we are familiar with today.
Among these fables are "The Tortoise and the Hare," "The Sheperd Boy and the Wolf" (a.k.a. "The Boy Who Cried Wolf"), and many other tales with a lesson behind them. Almost all of them are less than a page long. Almost all of them feature animals.
I can't really say either good or bad about this book. It is just a collection of disconnected stories, many of whose "morals" were lost on me. It's an easy read though, and I finished it in a few hours. The version I read was the Penguin Classics version, though there are many "kid friendly" versions out there.
