Leviathan by Scott Westerfeld

This book takes its readers to the beginnings of the Great War, reimagined in a world where the Central powers (here, Clankers) use mechanical technologies and the Allies (Darwinists) use genetically engineered animals. The perspective is centered around two youthful protagonists who have to learn the politics of the war very quickly if they want to survive in its changing landscapes. This book is no place to learn WWI history, but its engaging perspectives on genetic modification, industrialization, gender, and politics make it a thought-provoking and enjoyable read. I can't wait till the sequel comes out in October!
