I enjoyed this book because it is unique. It is about the "Great War" or: World War One. There are: Darwinists and Clankers. The Darwinists mix all sorts of animals cells together to breed big war animals. The Clankers build giant robots. The Darwinists are British and the Clankers are German. It is an alternate time line of World War One so it is historical fiction. I think people who are interested in cross breeding totally different species will love this book. If you want to read a book about animals versus robots this is a good book for you. I rate this 9 giant whales out of 10.
