In a postapocalyptic world of endless snow, eighteen-year-old Captain Romulus Buckle and the stalwart crew of the Pneumatic Zeppelin must embark on a perilous mission to rescue their kidnapped leader, Balthazar Crankshaft, from the impenetrable City of the Founders. Steaming over a territory once known as Southern California—before it was devastated in the alien war—Buckle navigates his massive airship through skies infested with enemy war zeppelins and ravenous alien beasties in this swashbuckling and high-octane steampunk adventure. Life is desperate in the Snow World, and death is quick. Buckle and his ship’s company must brave poisoned wastelands of Noxious Mustard and do battle with forgewalkers, steampipers, and armored locomotives as they plunge from the skies into the underground prison warrens of the fortress city.
Captain Romulus Buckle must lead the Pneumatic Zeppelin and its crew of ne’er-do-wells on a desperate mission where he must risk everything to save Balthazar and attempt to prevent a catastrophic war that could wipe out all that is left of civilization and the entire human race.
