Captain Swing and the Electrical Pirates of Cinderry Island is the story of a London constable in 1830 who tries to solve the murder of a fellow Peeler (or Bobby as the police are sometimes known) and gets mixed up with pirates in a flying electrical ship.
Written by Warren Ellis, it’s filled with cursing and scientific emancipatory exultation. Raulo Caceres’ art is dark and bloody. I liked it a lot. One of the cool things they do is have pages with the pirate captain discoursing in prose (over schematic engravings) explaining all sorts of history and background. It’s more effective than putting it in as expository dialogue, and enhances the notion of this being a document of secret history.
I haven’t read enough of Doktor Sleepless, but the two books feel connected. I’m unsure how deep that connection is.
