"A Tale of Two Cities" is a wonderful classic book by Charles Dickens. The story is about the causes of the French Revolution, different points of view, and a love story during it. The final part is what I love the most, but I liked this book since the first page. Although it is a fiction story, you can learn some things about the French Revolution and it is useful for social sciences. I totally recommend it, it's kinda long, but it's worth it.
