Plot Summary
Widow's Telegram
In the sweltering, blood-soaked laundry of a Richmond hospital, nurse Mercy Lynch learns her husband has died in a Union prison camp. The news, delivered by a Yankee and Clara Barton, shatters her fragile hope. Grief and numbness threaten to overwhelm her, but the relentless demands of war and the hospital force her to keep moving. When a telegram arrives from the distant Washington Territory, summoning her to her estranged father's deathbed, Mercy faces a crossroads. Torn between anger at her father's abandonment and the ache of loss, she chooses to leave the only life she knows, propelled by duty, curiosity, and the need to escape her sorrow.
A Reluctant Journey West
With her hospital days behind her, Mercy sets out across a fractured, war-torn America. She navigates the chaos of airship yards, crowded trains, and the ever-present threat of violence. Along the way, she meets a cast of strangers—some kind, some dangerous, all marked by the endless Civil War. The journey is a test of endurance and adaptability, as Mercy learns to trust her instincts and her skills as a nurse. Each stop brings new challenges, from mechanical marvels to the grinding realities of travel, and the shadow of her father's summons grows ever larger.
Airship Over Battlefields
Mercy boards the Zephyr, an airship bound for Tennessee, sharing cramped quarters with a motley group of passengers. As the ship skirts the front lines, the war's devastation is visible below—fires, moonshiners, and the scars of endless conflict. When the Zephyr is caught in crossfire and forced to crash-land near the front, Mercy's medical expertise becomes vital. Amid chaos, she witnesses the courage and desperation of both soldiers and civilians, and the boundaries between enemy and ally blur. The journey by air leaves her shaken, but more determined than ever.
Raiders and Warnings
Continuing by train, Mercy finds herself on a route plagued by Confederate raiders and shifting battle lines. The Dreadnought, a massive, armored Union engine, becomes her new conveyance—and a moving fortress. Onboard, tensions simmer between Union soldiers, civilians, and a mysterious Texian ranger, Horatio Korman. Sabotage and suspicion run rampant as the train is repeatedly attacked by bushwhackers and saboteurs. Mercy's role as a healer puts her at the center of the action, tending to the wounded and navigating the treacherous politics of a nation at war with itself.
The Dreadnought's Secret Cargo
As the Dreadnought barrels west, rumors swirl about its true purpose. Mercy discovers the train is carrying not only gold and land grants meant to recruit Chinese immigrants as Union soldiers, but also a sealed car filled with the bodies of men who died from a mysterious drug called "yellow sap." The presence of Mexican inspectors, Confederate spies, and a fanatical Union scientist, Malverne Purdue, adds layers of intrigue. The train becomes a microcosm of the war's moral ambiguities, with every passenger hiding secrets and every stop bringing new threats.
Allies and Enemies Aboard
Mercy forges uneasy friendships with passengers from all sides—Theodora Clay, a sharp-tongued Unionist; the enigmatic Korman; and Mexican officials searching for their missing countrymen. As sabotage and violence escalate, Mercy and her companions must decide whom to trust. The boundaries between friend and foe blur as survival takes precedence over politics. Mercy's compassion and pragmatism make her a reluctant leader, and her skills as a nurse become a lifeline for many. The journey west becomes not just a physical ordeal, but a crucible for character and conviction.
Sabotage in the Night
The Dreadnought is repeatedly sabotaged, its couplers tampered with and its progress slowed. Mercy, Korman, and others suspect a spy is aboard, feeding information to the pursuing Confederates. Tensions boil over when Malverne Purdue murders a suspected saboteur, and the fragile order aboard the train collapses into paranoia and fear. Mercy and Theodora risk everything to uncover the truth about the sealed car, discovering evidence of a deadly weapon in the making. The line between war and atrocity grows thin, and Mercy is forced to confront the cost of blind loyalty.
The Gold and the Dead
In a desperate bid to outrun the Confederate engine Shenandoah, the Dreadnought's crew jettisons cars to lighten their load. Mercy and her allies discover the sealed car contains not only gold and land deeds, but also the corpses of men killed by the yellow sap—a drug that turns its victims into mindless, ravenous husks. The Union's plan to weaponize the sap is exposed, and the moral rot at the heart of the war is laid bare. As the train races toward the mountain pass, Mercy realizes that the greatest threat may not be the enemy outside, but the secrets within.
The Shenandoah Pursuit
The Dreadnought and the Shenandoah hurtle toward the Provo Pass, each trying to outpace the other and avoid destruction. The Confederates hope to destroy the tracks and capture the gold, while the Union seeks to deliver its cargo to the West. The chase is a blur of gunfire, sabotage, and desperate heroics. Mercy, Korman, and their companions fight to keep the train moving, even as the odds grow longer and the dangers more surreal. The relentless pursuit pushes everyone to their limits, and the line between victory and annihilation narrows to a razor's edge.
The Undead Horde
As the trains near the pass, a new threat emerges: a horde of undead, the victims of the yellow sap, overruns the Shenandoah and turns on the Dreadnought. The living must unite against the mindless, insatiable dead. Mercy's medical knowledge and courage are tested as she fights to save the wounded and repel the attackers. The battle is brutal and costly, forcing former enemies to fight side by side. The true horror of the war is revealed—not in the clash of armies, but in the unleashing of forces beyond anyone's control.
The Tunnel and the Trap
The Dreadnought, battered and bloodied, is forced to halt in a mountain tunnel, trapped between the undead and the threat of sabotage. In the suffocating darkness, fear and exhaustion threaten to break the survivors. Mercy tends to the dying and wounded, her compassion a fragile bulwark against despair. When the train finally emerges into the light, the survivors are forever changed. The cost of survival is measured not just in lives lost, but in innocence and certainty destroyed.
Mercy's Reckoning
In the aftermath of the battle, Mercy is forced to confront the choices she has made and the person she has become. She has killed to survive, broken rules to save others, and witnessed the worst humanity has to offer. The journey has stripped her of illusions, but also revealed reserves of strength and resilience she never knew she possessed. As the Dreadnought limps into Salt Lake City, Mercy is both triumphant and haunted, her future uncertain but her resolve unbroken.
Salt Lake City Refuge
In Salt Lake City, the survivors of the Dreadnought's ordeal are given a hero's welcome, but the scars of their journey run deep. Mercy, Korman, the Mexican inspector, and the Confederate soldiers form an unlikely fellowship, united by shared trauma and mutual respect. Each must decide where to go next, and what to do with the knowledge they carry. Mercy's journey is not yet over, but she has found a measure of peace and purpose amid the ruins.
The Wall of Seattle
Mercy's final destination is the walled city of Seattle, a place poisoned by the same gas that created the yellow sap. Guided by Sheriff Briar Wilkes and Captain Andan Cly, Mercy descends into the city's underground, where survivors eke out a living beneath the deadly Blight. The city is a microcosm of the war's aftermath—divided, haunted, and struggling to find hope. Mercy's skills as a nurse are needed more than ever, and she is forced to confront the legacy of the war and the choices that brought her here.
Reunion Underground
In the depths of Seattle's underground, Mercy is reunited with her estranged father, Jeremiah Swakhammer. The meeting is awkward, fraught with unspoken regrets and the weight of years lost. Yet in the face of so much death and destruction, the possibility of forgiveness and healing emerges. Mercy's journey has come full circle, from loss and anger to acceptance and the hope of reconciliation.
The Poisoned City
As Mercy settles into life in Seattle, she is confronted by the ongoing dangers of the Blight and the ever-present threat of the undead. Yet she also finds community, purpose, and a sense of belonging among the city's survivors. The war may be over for her, but the struggle to build a new life—and to heal the wounds of the past—continues. Mercy's story is one of endurance, compassion, and the refusal to surrender to despair.
The Nurse's Burden
Throughout her journey, Mercy has been defined by her willingness to help others, even at great personal cost. Her skills as a nurse, her empathy, and her determination have saved lives and inspired those around her. Yet the burden of survival weighs heavily, and Mercy must learn to forgive herself for the choices she has made. In the end, her greatest strength is not her ability to heal wounds, but her capacity to endure and to hope.
The Price of War
The story closes with a meditation on the price of war—not just in lives lost, but in innocence, trust, and the fabric of society itself. The Dreadnought's journey is a microcosm of a nation torn apart, and Mercy's odyssey is a testament to the resilience of the human spirit. The lessons of the past linger, shaping the future in ways both hopeful and tragic. Mercy's story is not just her own, but the story of a world struggling to find meaning and redemption amid chaos.
Characters
Mercy Lynch
Mercy is a nurse forged in the crucible of endless war, marked by loss, compassion, and a stubborn will to survive. Her journey west is both a flight from grief and a quest for meaning, as she seeks her estranged father and a new life. Mercy's empathy is her greatest strength and her greatest vulnerability; she cannot turn away from suffering, even when it endangers her. Throughout the story, she evolves from a passive mourner to an active agent of change, making hard choices and facing the darkness within herself and others. Her relationships—with allies, enemies, and the wounded—reveal her complexity: pragmatic, nurturing, and fiercely independent. By the end, Mercy is transformed, her innocence lost but her hope intact, embodying the resilience and ambiguity of a world at war.
Horatio Korman
Korman is a lawman from the Republic of Texas, traveling incognito on the Dreadnought. Wry, resourceful, and skilled with both gun and wit, he is a man of shifting allegiances but unwavering principles. Korman's presence on the train is both a source of suspicion and a stabilizing force; he navigates the treacherous politics of the journey with a blend of pragmatism and dry humor. His relationship with Mercy is one of mutual respect and guarded trust, and he serves as both protector and provocateur. Korman's past is hinted at but never fully revealed, adding to his enigmatic appeal. He is a survivor, a realist, and—when it matters most—a man willing to risk everything for the greater good.
Theodora Clay
Theodora is Mercy's foil: educated, opinionated, and fiercely loyal to the Union. Initially prickly and suspicious, she gradually reveals a core of courage and adaptability. Her relationship with Mercy evolves from rivalry to partnership, as the two women join forces to uncover the train's secrets and survive its dangers. Theodora's intelligence and resourcefulness make her a valuable ally, and her willingness to challenge authority—sometimes recklessly—pushes the group forward. She is both a product of her time and a subversive force within it, challenging gender roles and expectations with every action.
Captain Warren MacGruder
MacGruder is the Dreadnought's captain, a man torn between orders, conscience, and the chaos around him. He is competent, brave, and increasingly disillusioned by the war's moral ambiguities. His interactions with Mercy and Korman reveal a man struggling to balance loyalty to his superiors with responsibility to those in his care. MacGruder's arc is one of gradual awakening, as he comes to question the true cost of victory and the nature of the enemy. He is both a symbol of the old order and a harbinger of change.
Malverne Purdue
Purdue is the Union's secret weapon: a brilliant, ruthless scientist obsessed with weaponizing the yellow sap. His presence on the train is a catalyst for much of the story's conflict, as his ambitions threaten to unleash horrors beyond anyone's control. Purdue is both villain and victim, driven by a belief in progress at any cost. His interactions with Mercy and the others expose the dangers of unchecked authority and the moral rot at the heart of the war effort. In the end, Purdue's downfall is both inevitable and tragic, a warning against the perils of dehumanization.
Inspector Javier Galeano
Galeano is one of two Mexican officials searching for their missing countrymen and the source of the yellow sap. Calm, diplomatic, and deeply principled, he serves as a bridge between cultures and a reminder of the war's wider consequences. Galeano's partnership with Korman and Mercy is built on mutual respect and shared horror at the unfolding catastrophe. His presence adds depth to the story's exploration of international politics, colonialism, and the unintended consequences of violence.
Mrs. Norene Butterfield
Mrs. Butterfield is a survivor of loss and upheaval, traveling west with her niece Theodora. She is both comic relief and a poignant reminder of the war's toll on families and the elderly. Her stubbornness and resilience are matched by a capacity for kindness, and her journey mirrors Mercy's in miniature: a search for safety, belonging, and meaning in a world turned upside down.
The Shenandoah Crew
The men of the Shenandoah are both enemies and, ultimately, fellow survivors. Their pursuit of the Dreadnought is driven by desperation and duty, but when faced with the greater horror of the undead, they join forces with their former foes. Their presence underscores the story's central theme: that the true enemy is not the other side, but the forces—human and inhuman—that threaten to destroy everyone.
Sheriff Briar Wilkes
Briar is Mercy's first contact in the Pacific Northwest, a tough, pragmatic sheriff who helps her navigate the dangers of the walled city. She is a survivor, a leader, and a symbol of the new communities emerging from the ruins of the old. Briar's friendship and guidance help Mercy find her place in a world forever changed by war and catastrophe.
Jeremiah Swakhammer
Swakhammer is the reason for Mercy's journey, a man haunted by his past and struggling to find redemption. Their reunion is fraught with regret, but also the possibility of forgiveness and healing. Swakhammer's story is a microcosm of the larger narrative: a tale of loss, endurance, and the hope of reconciliation in a world scarred by violence.
Plot Devices
The Journey as Transformation
The novel's structure is built around Mercy's westward journey, which serves as both a literal and metaphorical passage through grief, danger, and self-discovery. Each mode of travel—airship, train, riverboat—introduces new characters, challenges, and revelations, using the journey motif to explore themes of displacement, resilience, and the search for belonging. The relentless movement westward is both escape and pursuit, forcing Mercy and her companions to confront the past and imagine new futures.
The Train as Microcosm
The armored train is more than a setting; it is a crucible where the war's contradictions are distilled and magnified. Passengers from every side of the conflict are forced into uneasy proximity, their alliances and enmities shifting with each crisis. The train's secret cargo—gold, land deeds, and the deadly sap—serves as a symbol of the war's hidden costs and moral ambiguities. The claustrophobic environment heightens tension, suspicion, and the potential for both betrayal and solidarity.
Foreshadowing and Suspense
The novel employs foreshadowing through rumors, mysterious cargo, and the presence of spies and saboteurs. The gradual revelation of the yellow sap's effects, the sealed car of corpses, and the pursuit by the Shenandoah create a mounting sense of unease. Mercy's recurring encounters with the consequences of war—wounded men, addiction, and the undead—prepare the reader for the story's climactic horrors.
Moral Ambiguity and Shifting Allegiances
The story resists simple binaries of good and evil, North and South. Characters are forced to make hard choices, often with incomplete information and under extreme duress. The presence of spies, double agents, and secret agendas blurs the line between ally and enemy. Mercy's compassion and pragmatism serve as a moral anchor, but even she is forced to compromise and adapt.
The Undead as Metaphor
The emergence of the undead, created by the weaponized sap, is both a plot twist and a metaphor for the war's corrosive effects on humanity. The mindless, insatiable dead are the ultimate consequence of treating people as expendable resources. Their appearance forces former enemies to unite, highlighting the futility of old hatreds in the face of existential threats.
Narrative Structure and Perspective
The novel's perspective is tightly focused on Mercy, allowing the reader to experience her confusion, fear, and growth firsthand. The use of present-tense urgency in action scenes, and more reflective passages in moments of respite, creates a dynamic rhythm. The story's episodic structure—each leg of the journey a self-contained ordeal—mirrors the unpredictability and fragmentation of life in wartime.
Analysis
Cherie Priest's Dreadnought is a steampunk odyssey that uses the conventions of alternate history and horror to interrogate the true costs of war—personal, moral, and societal. Through Mercy Lynch's journey, the novel explores themes of grief, resilience, and the search for meaning in a world shattered by violence and betrayal. The Dreadnought itself becomes a symbol of a nation divided, its passengers forced into uneasy alliances as they confront not only external enemies but the darkness within their own ranks. The introduction of the undead, created by the weaponized yellow sap, literalizes the dehumanization and moral rot at the heart of endless conflict. Priest's narrative resists easy answers, instead offering a meditation on the ambiguity of heroism, the necessity of compassion, and the possibility of redemption amid ruin. In the end, Dreadnought is less about victory or defeat than about survival, endurance, and the hope that, even in the aftermath of catastrophe, new communities and new futures can be forged.
