I hoped for more out of this book.
I like the story. It’s an interesting premise and a great use of steampunk themes to build an alternate universe. Leviathan re-envisions the start of World War I as a conflict between two pathways of technological development. The Darwinists, in England, France, and Russia, have gone into biodevelopment, discovering things like DNA coding a bit ahead of time, and using that knowledge to create fantastical new creatures. Airships made out of floating air-whales with other creatures grafted on, balloons out of jellyfish/blowfish type things, lizards who can memorise and deliver messages, wolf-dog-tiger hybrids for security or searching. The Clankers, in Germany/the Holy Roman Empire (still hanging on, apparently) and most of Eastern Europe, have chosen traditional mechanical technology, viewing Darwinist creations as hellish abominations.
The trouble is that, well… there sort of just wasn’t enough there.
