The story starts with a wise patriarchal pig gathering the farm animals around him and telling about a dream he just had. Their human oppressors will be overthrown and the animals will live together in peace and cooperation. Not only does his vision divulge this veritable Utopia, but the ancient and long lost song "Beasts of England" is revealed to him. Soon after, the old pig dies, and the animals indeed do revolt against the humans, using this vision and song as their talisman. At first, though life is hard and full of work, the animals feel their freedom like an exhilirating breeze. But the remaining pigs start to subtly become more and more ambitious until things seem to be taking a U-turn back to the days of the humans.
Of all the books I've ever read, this book probably is most comparative to The Lord of the Flies in that they both express what a race would deteriorate into if there were nobody to hold it accountable. This book was definitely thought-provoking, interesting and entertaining.
