Leviathan

Scott Westerfeld

"Leviathan," written by Scott Westerfeld and published in 2009, is the first book in a steampunk-inspired trilogy that reimagines the events leading up to and during World War I. The novel presents an alternate history where the world is divided into two factions: the Darwinists, who use genetically engineered creatures for warfare, and the Clankers, who rely on advanced machinery and steam-powered technology. 


The story follows two young protagonists—Prince Aleksandar of Austria-Hungary and Deryn Sharp, a girl disguised as a boy to serve in the British Air Service—whose paths cross as they become embroiled in the conflict. Westerfeld's novel explores themes of identity, loyalty, and the clash between tradition and innovation.

Summary of the Novel

The novel begins with the assassination of Archduke Franz Ferdinand and his wife, Sophie, an event that plunges Europe into war. Prince Aleksandar, the son of the Archduke, is forced to flee his home in Austria-Hungary to escape those who seek to eliminate him as a potential heir to the throne. Accompanied by a small group of loyal men and a walker (a large, mechanical war machine), Alek makes his way across Europe, evading capture and grappling with his new status as a fugitive.


Meanwhile, in Britain, Deryn Sharp, a young girl with a passion for flying, disguises herself as a boy named Dylan and joins the British Air Service. She is assigned to the Leviathan, a massive airship made from genetically engineered creatures, including a whale-like creature that serves as the ship's core. Deryn's journey is one of deception and determination, as she must keep her true identity hidden while proving herself as a capable airman.


As the war intensifies, Alek and Deryn's paths cross when Alek's walker is damaged and the Leviathan crash-lands in the Alps. Despite their initial mistrust—Alek is a Clanker and Deryn is a Darwinist—the two form an alliance, recognizing that their survival depends on cooperation. Together, they face numerous challenges, including attacks from enemy forces, treacherous terrain, and the secrets each is keeping. The novel ends with Alek and Deryn preparing to embark on a new adventure aboard the Leviathan, as they continue to navigate the complexities of war and their evolving relationship.

Key Themes & Motifs

Identity and Deception: The theme of identity is central to "Leviathan," particularly through the characters of Alek and Deryn. Both protagonists grapple with questions of identity—Alek as a prince without a kingdom and Deryn as a girl disguised as a boy. Their need to hide their true selves reflects the broader theme of deception, both personal and political, in a world at war. The novel explores the tension between societal expectations and individual desires, as well as the challenges of maintaining one's identity in the face of external pressures.

The Clash Between Tradition and Innovation: The novel presents a world divided between the Darwinists, who embrace biological innovation, and the Clankers, who rely on mechanical technology. This dichotomy represents the broader theme of tradition versus innovation, as both sides seek to gain an advantage in the war. The novel explores the ethical and practical implications of each approach, raising questions about the consequences of technological and scientific advancements. The conflict between the Darwinists and Clankers serves as a backdrop for the characters' personal journeys, highlighting the ways in which innovation can challenge traditional beliefs and power structures.

Loyalty and Betrayal: Loyalty and betrayal are recurring themes in "Leviathan," as the characters navigate the complexities of war and alliances. Alek's loyalty to his family and country is tested as he comes to terms with the realities of his situation, while Deryn's loyalty to her country is complicated by her need to conceal her true identity. The novel also explores the concept of loyalty on a broader scale, examining the shifting alliances and betrayals that characterize the political landscape of wartime Europe. The characters' struggles with loyalty and betrayal reflect the moral ambiguities of war and the challenges of making ethical decisions in a world where trust is often in short supply.
