Leviathan Westerfeld

Alek and Deryn are on the last leg of their round-the-world quest to end World War I, reclaim Alek’s throne as Prince of Austria, and finally fall in love. The first two objectives are complicated by the fact that their ship, the Leviathan, continues to detour farther away from the heart of the war (and crown). And the love thing would be a lot easier if Alek knew Deryn was a girl. (She has to pose as a boy in order to serve in the British Airforce.) And if they weren’t technically enemies.

It is the cusp of World War I, and all the European powers are arming up. The Austro-Hungarians and Germans have their Clankers, steam-driven iron machines loaded with guns and ammunition. The British Darwinists employ fabricated animals as their weaponry. Their Leviathan is a whale airship, and the most masterful beast in the British fleet.

If Leviathan was setting up World War One with mechs and genetically engineered creatures, Behemoth was expanding upon the political ramifications. The book primarily centers on the political machinations between the Darwinist English and the Clanker Germans vying for the favor of the kind-of-sort-of Clanker Ottoman Turks in Istanbul. In the middle of this is Alek, son of the nobles whose assassination lit off the whole mess, and Deryn/Dylan the crossdressing girl serving on the English airship Leviathan and crushing over Alek.

The behemoth is the fiercest creature in the British navy. It can swallow enemy battleships with one bite. The Darwinists will need it, now that they are at war with the Clanker powers.
