Destiny meets history in the complete boxed set of the riveting, New York Times bestselling Leviathan trilogy. 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. In this striking futuristic rendition of an alternate past where machines are pitted against genetically modified beasts, Aleksandar Ferdinand, a Clanker, and Deryn Sharp, a Darwinist, are on opposite sides in the First World War. But their paths cross in the most unexpected way, and together they embark on an around-the-world adventure... One that will change both their lives forever. This collectible boxed set contains the complete Leviathan trilogy: Leviathan, Behemoth, and Goliath.
