I feel like a lot of people missed out on Scott Westerfeld’s excellent novel, LEVIATHAN.
It’s an alternate history version of World War I in which the Germans have developed giant armored war machines and the British have found a way to reconstruct animal DNA in order to create battle-ready animal-vehicle hybrids.
In this video, Westerfeld takes you with him on his trip to learn more about the real-life airships that inspired the ones in his novel.
