Book 1

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 which could wipe out all that is left of civilization and the entire human race.

Book 2

The frozen wasteland of Snow World—known as Southern California before an alien invasion decimated civilization—is home to warring steampunk clans. Crankshafts, Imperials, Tinskins, Brineboilers, and many more all battle one another for precious supplies, against ravenous mutant beasts for basic survival, and with the mysterious Founders for their very freedom.

Through this ruined world soars the Pneumatic Zeppelin, captained by the daring Romulus Buckle. In the wake of a nearly suicidal assault on the Founders’ prison city to rescue key military leaders, both the steam-powered airship and its crew are bruised and battered. Yet there’s little time for rest or repairs: Founders raids threaten to shatter the fragile alliance Buckle has risked everything to forge among the clans.

Even as he musters what seems a futile defense in the face of inevitable war, Buckle learns that the most mysterious clan of all is holding his long-lost sister in a secret base—and that she holds the ultimate key to victory over the Founders. But rescuing her means abandoning his allies and praying they survive long enough for there to be an alliance to return to.
