The pigs, the pigs. A shorter story, but still is one of my favorites, I loved the charming characters, and even though it was a pretty harsh book, it was still a delight.
Animal Farm is one of my favorite books because it's point was to show the differences between Socialism and Russian Communism, and that Stalin's regime was his own doing and not the said principles of Communism itself.
Orwell is a very talented writer and both Animal Farm and 1984 are not only filled with symbolism through expression but also with excitement.
