Leviathan plot
In 1914, two powers confront each other in Europe: the Darwinists, who use genetically modified animals, and the Crankers, who have developed a mechanical civilization with steam engines and diesel motors. In this world, Prince Alec is hunted by the same group that murdered his parents. At the same time, a girl named Sharp, disguised as a boy, enlists in the British Royal Air Force. There, Alec and Sharp arrive together aboard the flying beast Leviathan and embark on an adventure that will change the world.
