It is 1914 and Europe is on the brink of war. In Austria-Hungary young Prince Aleksander’s life is suddenly in turmoil. His parents have been murdered and he is on the run and in disguise. His once-upon-a-time allies have turned out to be enemies and there are very few people he can trust. In England Deryn Sharp wants nothing more than to be an airman. The only problem is, she’s a girl, and airmen are.. well, male. In disguise she gets accepted and is soon serving as a Midshipman aboard the Leviathan. A huge airship built around a fabricated beast.
