Orwell is known openly writing politically charged books that speak out against totalitarianism. In his article, "Why I Write," Orwell himself puts it best:
Every line of serious work that I have written since 1936 has been written, directly or indirectly, against totalitarianism.... Animal Farm was the first book in which I tried, with full consciousness of what I was doing, to fuse political purpose and artistic purpose into one whole.
Told entirely from the point of view of the animals on the farm, Animal Farm is a unique political commentary that is both a short and entertaining read, even if you aren't normally a reader if political writings.
