George Orwell is certainly one of the best. His work is always so relevant, and it's astonishing just how well he understands the progression of society and intentions of the government, enough to keep his writing thought-provoking decades later. In the context of animals on a farm, Orwell's exploration of socialism, communism and democracy is perfect. Those three words are all subjects I never thought I would find interesting topics in a book, but Orwell knows how to entice an audience while exploring quite mundane but hard-hitting subjects, whilst also making the story entertaining and engaging.
