A steampunk prince and a cross-dressing airman race to uncover the true loyalties of a maniacal inventor and his war-ending weapon, all while navigating their own burgeoning forbidden romance amidst the thunderous final throes of a global conflict.
Alek and Deryn are aboard the British airship Leviathan, still operating under the guise of being a commoner and a boy, respectively. Their journey takes an unexpected turn when they are ordered to divert to pick up a new passenger: the Serbian-American inventor Nikola Tesla. Tesla is a reclusive and eccentric scientist, known for his radical ideas and inventions. He claims to have developed a weapon, which he calls 'Goliath,' that could single-handedly end the Great War. The crew, including Alek and Deryn, are skeptical and wary of this new development, given Tesla's unpredictable nature and the secrecy surrounding his invention. The Leviathan's primary mission of delivering Alek safely to his allies is now complicated by the addition of this volatile new element and the potential for a world-changing weapon.
The Leviathan transports Nikola Tesla to an isolated island in the Pacific, where his hidden laboratory is located. Alek and Deryn, along with the crew, are given limited access to the facility. Tesla, with his peculiar habits and demanding demeanor, begins to set up his experiment. He reveals that the 'Goliath' is not a conventional weapon, but rather a device capable of generating immense, localized seismic activity—essentially a man-made earthquake machine. During a demonstration, the Goliath unleashes its destructive power, causing a small, uninhabited island to crumble into the sea. The sheer scale and indiscriminate nature of the weapon's power shock Alek and Deryn, who begin to question the morality of using such a device, regardless of the war's stakes.
While on a reconnaissance mission or simply during a moment of vulnerability, Alek accidentally discovers Deryn's most closely guarded secret: she is, in fact, a girl disguised as a boy. This revelation shatters Alek's perception of his closest friend and confidante. He struggles to reconcile the 'boy' he has known and trusted with the reality of Deryn's female identity. The discovery is both shocking and confusing for Alek, but also brings a new layer of understanding and complexity to their bond. Deryn, for her part, is mortified and terrified that her secret is out, fearing rejection and the end of her career in the British Air Service. This moment marks a critical turning point in their relationship, forcing them to confront their true feelings for each other.
Following the revelation of Deryn's gender, an awkward and tense period ensues between her and Alek. Alek grapples with his feelings, realizing that his deep affection for 'Dylan' was always for Deryn, the person, regardless of her perceived gender. Deryn, meanwhile, is consumed by anxiety, unsure how Alek will truly react and what this means for their future, both personally and professionally. Their previously uncomplicated friendship is now charged with unspoken emotions and the weight of Deryn's secret. They have to navigate the implications of this new reality while still performing their duties aboard the Leviathan and dealing with the constant threat of war and Tesla's unpredictable agenda. The close quarters of the airship make it impossible to avoid each other, forcing them to confront their feelings head-on.
As the Leviathan continues its journey with Tesla and the Goliath, 'Clanker' forces, primarily German and Austro-Hungarian airships and land walkers, become more aggressive and frequent in their attacks. The war effort is intensifying, and the British airship finds itself in increasingly dangerous territory. Tesla's intentions for the Goliath become clearer: he plans to use it to destroy Constantinople (Istanbul), a strategically vital city, believing its destruction will cripple the Central Powers and end the war. This proposition deeply disturbs Alek and Deryn, who see the massive civilian casualties such an act would entail. They begin to actively question Tesla's judgment and the morality of deploying such a devastating weapon against a populated area, even in the name of peace.
Alek and Deryn find themselves in a moral quandary. Their superiors, particularly Dr. Barlow, are keen on the potential of the Goliath to end the war, even if it means immense destruction. However, Alek, as a prince and future emperor, feels a strong sense of responsibility for the lives of civilians, regardless of their nationality. Deryn, too, is horrified by the prospect of mass slaughter. They are caught between their loyalty to their respective nations and their own ethical compass. This internal conflict is exacerbated by Tesla's unwavering conviction in his plan and his dismissal of their concerns. They must decide whether to follow orders or to actively resist the deployment of a weapon they deem inhumane.
As Alek and Deryn investigate Tesla and his motives more closely, they begin to uncover inconsistencies and suspicious activities. They realize that Tesla's intentions might not be as straightforward as simply ending the war for the Allies. Through careful observation and a bit of clandestine snooping, they discover evidence suggesting that Tesla has a more personal, perhaps even vengeful, agenda. His allegiances appear to be fluid, and his ultimate goal seems to be less about global peace and more about demonstrating his own power and settling old scores. They suspect he might be playing both sides or acting entirely on his own, using the war as a pretext for his grand, destructive experiment. This revelation confirms their fears about the Goliath's use.
Armed with their new understanding of Tesla's true intentions, Alek and Deryn decide they cannot allow the Goliath to be used as planned. They confront Tesla, challenging his motives and the morality of his actions. The confrontation is fraught with tension, as Tesla, brilliant but increasingly unhinged, dismisses their concerns. He reveals his deeper, personal reasons for targeting Constantinople, which are rooted in past grievances and a desire for recognition. It becomes clear that Tesla has been manipulating both sides to some extent, and his ultimate loyalty is to his own scientific ambition. This betrayal of trust solidifies Alek and Deryn's resolve to stop him, even if it means defying direct orders.
The Leviathan arrives at Constantinople, and Tesla prepares to unleash the Goliath. Alek and Deryn, with the help of a few loyal crew members who share their moral objections, devise a desperate plan to sabotage the weapon. They must act quickly, as the city below is unaware of the impending doom. The climax involves a tense race against time within Tesla's laboratory aboard the Leviathan, as Alek and Deryn attempt to disable the Goliath while simultaneously fending off Tesla's loyalists and the inventor himself. The fate of Constantinople, and potentially the entire war, hinges on their success or failure in preventing this catastrophic act of destruction.
In a climactic struggle, Alek and Deryn manage to disable the Goliath, preventing the destruction of Constantinople. The immediate threat is averted, but the implications of Tesla's actions and the near-catastrophe resonate deeply. In the aftermath, the war continues, but the world has witnessed the terrifying potential of unchecked scientific power. Alek and Deryn, having faced death and moral dilemmas together, finally acknowledge their profound love for each other. Alek, now fully embracing his role as a future leader, promises to protect Deryn and ensure her rightful place by his side, regardless of her humble origins or her past deception. The book concludes with a sense of hope for their future and a more nuanced understanding of the path to true peace.

The novel deeply explores the ethical implications of developing and deploying super-weapons, particularly through Nikola Tesla's 'Goliath.' While Tesla believes his invention can end the war quickly, Alek and Deryn grapple with the immense civilian casualties and indiscriminate destruction it would cause. This theme questions whether the 'ends justify the means' in warfare. The characters' debate over Constantinople's fate directly showcases the conflict between strategic victory and humanitarian concerns.
“"Is peace worth any price? Even if that price is paid in the lives of innocents?"”
Both Alek and Deryn undergo significant journeys of self-discovery. Deryn's entire existence aboard the Leviathan is built on a fabricated identity, and the revelation of her true gender forces her to confront who she truly is and what she desires. Alek, too, struggles with his identity as a prince and a leader, learning to reconcile his royal duties with his personal moral code. The book explores how external circumstances and personal choices shape one's sense of self, and how true identity can blossom when secrets are revealed and accepted. Their journey together is as much about finding themselves as it is about finding each other.
“"The hardest thing wasn't being a boy, it was being me, underneath it all, and wondering if anyone would ever see her."”
A central theme is the romance between Alek, a prince of the Austro-Hungarian Empire, and Deryn, a commoner British girl disguised as a boy. Their love defies social class, national allegiances (initially), and gender expectations. The revelation of Deryn's gender intensifies this theme, forcing both characters to confront their feelings and the societal barriers they face. Their relationship illustrates that true connection transcends superficial differences and that love can flourish even amidst the chaos of war, offering a beacon of hope and personal connection in a world torn apart.
“"It wasn't the uniform, or the title, or even the gender. It was her, always her, that he cared for."”
The novel examines different forms of power: the political power of royalty (Alek), the military power of nations (Britain, Central Powers), and the scientific power of invention (Tesla). It questions what constitutes good leadership, contrasting Alek's evolving sense of responsibility with Tesla's destructive ambition. Alek learns that true leadership involves not just authority but also moral courage and compassion for all people, not just one's own. The choices leaders make, especially in wartime, have profound consequences, and the book highlights the burden of wielding immense power responsibly.
“"A crown isn't just a symbol, Deryn. It's a promise, to protect everyone, even those you've been taught to call enemies."”
A powerful, mysterious object that drives the plot forward.
The 'Goliath' weapon serves as the central MacGuffin of the story. Its existence and the potential for its use drive the entire plot, dictating the Leviathan's mission, introducing Nikola Tesla, and creating the central moral conflict. While its destructive power is demonstrated, its primary function in the narrative is to propel the characters into increasingly dangerous situations and force them to make difficult ethical choices, rather than being the ultimate solution itself. The quest to control or stop the Goliath is what brings Alek and Deryn to their final confrontation.
A character concealing their true self, creating tension and dramatic irony.
Deryn Sharp's secret identity as a girl disguised as a boy is a foundational plot device throughout the series, and its revelation in 'Goliath' is a major turning point. This device creates constant tension, as Deryn lives in fear of discovery, and provides opportunities for dramatic irony when other characters unknowingly comment on 'Dylan.' Its ultimate exposure forces a re-evaluation of relationships and feelings, particularly between Deryn and Alek, moving their dynamic from platonic friendship to romantic love and challenging societal norms.
A situation where characters must choose between two undesirable or conflicting options.
The novel is replete with moral dilemmas, most notably the decision regarding the use of the Goliath weapon. Alek and Deryn face the choice between following orders to unleash a devastating weapon that could end the war but cause mass civilian casualties, or defying their superiors to prevent such an act. This device highlights the characters' internal struggles, their evolving moral compasses, and the complex ethics of wartime decisions. It forces them to question authority and decide where their true loyalties lie: to their nations, to humanity, or to each other.
Hints or clues about future events, particularly Tesla's unpredictable nature.
From the moment Nikola Tesla is introduced, his eccentricities, reclusiveness, and radical ideas serve as foreshadowing for his eventual antagonistic role and the dangerous nature of the Goliath. His initial demands, his isolated laboratory, and the sheer power demonstrated in early tests all hint that his intentions might be more complex and destructive than initially presented. This device builds suspense and prepares the reader for the inevitable moral conflict that arises when his true agenda for the Goliath is revealed, making his eventual betrayal feel earned rather than sudden.
