Goliath is a fitting conclusion to Scott Westerfeld’s Leviathan trilogy. While Leviathan and Behemoth both referred to Darwinist creations in their titles, Goliath is an electrical super-weapon designed by Nikola Tesla to end the Great War.
The story follows Alek and Deryn as they ride the airship Leviathan over Siberia to Japan then California, Mexico and New York. The plot in this one was a little bit less urgent and more episodic. Alek is desperately trying to find a way to end the war, but can only really find a role in being an assistant to Tesla, while Deryn’s disguise as a boy is the big thing at risk for her in the book. It relied a bit more on meeting real people from history than the previous books as well.
But the climax was thrilling and fit the story perfectly, there were giant fighting bears (sadly not in the climax) and the thing ends happily. Good steampunk; great story.
