Paris in the Twentieth Century

Written by Jules Verne in the mid-19th century, this novel was his idea of what the ‘future' would look like. I always find books like this fascinating: they always end up having some things fairly right, and some things that are way off, and the future in question generally tells us more about the culture that created it rather than the actual future. In that sense, it's an amazing book, although Verne definitely improved as an author between this book and his later works.
