Best-selling author Scott Westerfeld's novels include the Uglies series and the Midnighters trilogy. In Goliath, Alek and Deryn are on the last leg of their round-the-world quest to end World War I and reclaim Alek's throne as prince of Austria. Their objectives, however, are complicated by the fact that their ship, the Leviathan, continues to detour farther away from the heart of the war.
