It is the cusp of World War I. The Austro-Hungarians and Germans have
their Clankers, steam-driven iron machines loaded with guns and
ammunition. The British Darwinists employ genetically fabricated animals
as their weaponry. Their Leviathan is a whale airship, and the most
masterful beast in the British fleet.
Aleksandar Ferdinand, a Clanker, and Deryn Sharp, a Darwinist, are on
opposite sides of the war. But their paths cross in the most unexpected
way, taking them both aboard the Leviathan on a fantastical,
around-the-world adventure....One that will change both their lives
forever.
