In the conclusion to Scott Westerfeld’s steampunk World War I series, the Leviathan is sent to pick up a mysterious inventor who plans to stop the war with his latest device (Goliath), and Deryn’s secret is finally revealed. Once the Leviathan has transported the inventor to America, Alek meets Eddie Malone, a reporter for The New York World, and the Prince’s story and secrets are finally revealed to the world. I really couldn’t put this book down, wanting to know what was to become of Alek and Deryn, and how their relationship would develop. The book’s many plot twists, cliffhangers, and near-disasters build momentum until Alek must make his final decision: his title as emperor, or Deryn. I think this series will please fans of adventure, action, steampunk, and historical fiction and is sure to make a lasting impression.
