Leviathan by Scott Westerfeld
Choose your weapon: Beastie or Clanker.
"Alek is a prince without a throne. On the run from his own people, he has only a fighting machine and a small band of men.
Deryn is a girl disguised as a guy in the British Air Service. She must fight for her cause-and protect her secret-at all costs.
Alek and Deryn are thrown together aboard the mighty airship Leviathan. Though fighting side by side, their worlds are far apart. British fabricated beasts versus German steam-powered war machines. They are enemies with everything to lose, yet somehow determined to be together."
