Grandville
This 2009 graphic novel seems to have done sufficiently well to produce a recent sequel, Grandville Mon Amour. It is a rather odd beast, presenting us with a story set in a world where France won the Napoleonic Wars and still rules the continent in the early 21st century, with Britain having been granted independence only a few decades earlier. The story is mostly set in Paris, now renamed Grandville (hence the title), now a kind of steampunk theme park with excitingly retro-futuristic technology.
