The Iron Moon is a graphic novel written by Stephen Walsh and drawn by Keith Page, published by Print Media in March 2011. A skewed steampunk space adventure set on the cusp of a different 20th century than the one you might be familiar with, it features Charlotte Corday, who previously appeared in Walsh and Page's London Calling. In this one of her many incarnations, she's a lieutenant in Queen Victoria's Royal Space Navy who discovers a conspiracy that could plunge the galaxy into war, along the way meeting aliens, mechanical beasties and even visiting the grave of Oscar Wilde. Which isn't in Paris.
A short prequel Charlotte Corday adventure, On Her Majesty's Hush-Hush Service, appeared in November 2011, in the first issue of Print Media's Strip magazine.
