Goliath (Leviathan #3)

Goliath by Scott Westerfeld is the conclusion of the Leviathan trilogy (except that his last trilogy ended up having four books, so fans can still hope for more!). The premise of the series is that instead of just discovering evolution, Darwin discovered DNA as well. As a result some countries developed machinery while others used DNA to create new type of beasts.

The Leviathan, the British airship, was created from whale DNA. It is a living, breathing ship that flies it crew around the sky. A whole ecosystem exists inside of it.

In this conclusion to the series, Dylan Sharp (actually Deryn disguised as a boy to join the service) and Prince Alek continue to do their part to help bring the war to an end. The Leviathan will make a detour to rescue a scientist who claims to be able to end the war with his contraption - the Goliath.

In this volume, Alek will discover Deryn's secret. The Leviathan will travel to many foreign lands. And a mad scientist will affect the outcome of the war.

Westerfeld has created a dynamic, steampunk alternative history of the Great War. His characters are compelling and his plot genius. Fans of so many different elements of story will delight in this series.
