I just read the book in one day and at first I thought it would be really boring and I wouldn't understand it at all but from the first chapter I got hooked and spent the whole of my Saturday until I finished it sometime in the evening. It's really short and I would recommend it to everyone cuz it can pertain to many different subjects in terms of power and abuse.But to answer your question,I believe animal farm is a good book because it is an excellent allegory for the Russian Revolution.
