How the Book Is Structured
Alchemised is a 1,024-page standalone dark fantasy organized into three Parts — three interleaved timelines, all centered on the same protagonist, Helena Marino. There is a prologue, 77 numbered chapters, and an epilogue.
Part One — "Now" (Prologue and Chapters 1–21), set in 1788 PD
Helena wakes from fourteen months of magical stasis into a Paladia ruled by the High Necromancer Morrough and his Undying. Her memories have been alchemically erased. She is handed over to the regime's most feared general, the High Reeve Kaine Ferron — her former Alchemy Institute rival — who is tasked with extracting whatever secret her mind is hiding.
Part Two — "Before" (Chapters 22–65), set 1785–1787 PD
The longest section of the book: a sustained flashback through the final years of the war between the Order of the Eternal Flame and the Undying. Here we learn that Kaine was a Resistance double agent and that he and Helena were lovers — and that this is the very thing Helena erased from her own mind.
Part Three — "After" (Chapters 66–77 plus Epilogue), set 1789 onward
The novel returns to the present at Spirefell as Helena's memories crash back. The endgame against Morrough plays out, followed by a long denouement and an epilogue set nearly two decades later.
A deeper layer — fragments of Helena's earlier life and her years at the Lapis Atrium with Kaine — surfaces throughout in dreams, transference flashes, and recovered memories. There is no neat alternation between layers; SenLinYu lets them collide.
A note on the magic system, because it governs everything: every alchemist has a resonance keyed to specific matter. Most channel it into metalwork. Defective souls (per the Order's theology) bend it into vivimancy (healing the living), necromancy (animating the dead), or the rarest and most feared discipline, animancy (reading and rewriting minds and souls). Helena is publicly a vivimancer but secretly an animancer — and the difference will save her life. Kaine, an iron alchemist by birth and one of Morrough's "ascendant" Undying, has been forcibly mutated into a necromancer.
Part One — The Now Timeline
Prologue: The Tank
Helena Marino floats conscious inside a sensory-deprivation stasis tank, paralyzed but aware, marking time only by tri-hourly electric jolts that keep her muscles from atrophying. She does not know how long she has been there. To keep from going mad she recites books and walks she has loved, imagines cliffs and skies, and refuses to let herself fade. The prologue establishes the book's central wager: Helena's will to endure, even when there is no longer anyone left to endure for.
Chapter 1: Awakening
Light splits her skull as orderlies haul her out of the tank. She vomits stasis gel and convulses while a clinical voice — later identifiable as Dr. Stroud — notes that Helena has two prisoner numbers, 1273 and 19819, and "should be dead." Memory shards return: the Alchemy Tower, the Order of the Eternal Flame, Morrough, the necrothralls. She learns the war is over, that the Holdfasts have fallen, that Luc Holdfast — her best friend, the Principate, the prophesied leader of the Resistance — is dead, and that fourteen months have passed without anyone ever coming for her.
Chapter 2: Mandl, Stroud, Morrough
She is moved to the repurposed Alchemy Tower. Stroud uses cold resonance to paralyze her and confronts the warden, Mandl, who tearfully confesses that she had personally rerouted Helena's paperwork out of jealousy and locked her into the tank conscious as a private cruelty before being promoted. Morrough himself then emerges — shrunken, half-rotten, kept alive by feeding on his Undying. He orders nullification tubes driven through Helena's wrists to choke off her resonance. The Eastern metallurgist Shiseo is forced to fit her with lumithium-laced manacles; he meets her eye and whispers, I am sorry. Helena recognizes him as someone she knew but cannot place how.
Chapters 3–4: The Tower and the High Reeve
In the Tower, Helena sees the wreckage of the people she once worked beside — a lich wearing the body of a friend, a broken Penny — while Stroud sneers at the Holdfasts' fallen legacy. She is then handed to the regime's most powerful figure, the High Reeve Kaine Ferron, master of the Iron Guild and her old rival from the Alchemy Institute. Morrough has ordered Kaine to perform transference — a near-sexual, mind-invasive procedure — to recover whatever the Resistance buried in Helena's brain. Her body flinches at Kaine before her brain understands why.
Chapter 5: Spirefell
Kaine takes Helena to Spirefell, his crumbling iron-bound family estate. Aurelia Ferron, Kaine's wife, is openly venomous about her husband bringing home a "prisoner-mistress." The first transference is excruciating; Kaine finds nothing of use and gives Helena emotion-numbing tablets to "acclimate" her. He is cold, formal, indifferent.
Chapters 6–7: Cages
Helena explores the manor and finds three things she shouldn't: Stroud's notes on a Repopulation Programme, fresh surgical scars on her own body, and reanimated eyes set in glass plaques that let Kaine watch her in every room. The estate's wrought iron has been alchemically shaped into a cage to prevent suicide. She overhears Kaine dominating the lich of his own father, Atreus Ferron, by manipulating the iron in the floor. A clear memory of Luc before the final battle surfaces unbidden.
Chapters 8–9: Lancaster and the Tablets
A second transference leaves Helena seizing; she wakes to find Kaine has cared for her himself — a tenderness that doesn't match the cruelty. He gives her leather boots and warm gloves for winter. A man named Erik Lancaster, a former Institute classmate now in the Nickel Guild, breaks into her room and seems to recognize her in a way that makes her skin crawl; Kaine intervenes. Stroud returns, furious at Helena's emaciation — Aurelia has been feeding her necrothrall scraps — and orders Kaine to keep her properly fed.
Chapter 10: Solstice
During Aurelia's solstice party, Helena sneaks through the manor and stumbles onto Aurelia having sex with Lancaster, then eavesdrops on Kaine in a tense political call with Fabian Greenfinch, head of the Guild Assembly, after which Kaine ends the call by ordering an entire family executed. The dissonance — cruel for the regime, careful with her — is unbearable.
Chapters 11–12: The Plaque
Kaine catches her hunting for weapons and they argue about Luc, the Order, and her right to die. She finds a memorial room with a plaque bearing the name Enid Ferron — Kaine's mother. Dreams about Lila Bayard and Lila's brother Soren start tearing at her sleep. Stroud snipes at Kaine about Helena's weight loss.
Chapter 13: The Knife, the Assassination, the Animancer
Helena steals a knife and tries to assassinate Kaine; he stops the blade bare-handed. News arrives that Warden Mandl has been assassinated in the dead of winter — proof, Helena hopes, that the Resistance has not been wholly extinguished. Kaine is then summoned to Morrough's lair and brings Helena with him. Morrough performs the transference himself and discovers what Kaine missed: Helena is an animancer, and she erased her own memories. Kaine is brutally punished for failing to detect it. Afterward, Helena is told she was the one who bombed the West Port Laboratory at the end of the war — and she finally lets herself remember that the boy who killed Luc's father, the Principate Apollo Holdfast, was a sixteen-year-old Kaine Ferron, the murder that started the war.
Chapters 14–15: The Party and the Needle
Helena pieces together that Morrough is dying and draining the Undying like a battery — which means Kaine, too, is bound to him by something more than fear. At Aurelia's spring equinox party, Helena overhears horrific war stories and worries about the women warehoused at "Central." Lancaster slips into her room and sticks a needle into her neck, evidently with Aurelia's blessing.
Chapter 16: Disembowelment and the Iron House
Lancaster tries to rape Helena. Kaine arrives, disembowels him, and saves her. The next day Aurelia confesses, with a kind of broken pride, that she was bred from a cousin marriage by her parents specifically to be Kaine's wife and that he has refused her for years. In a jealous rage she attacks Helena and tries to gouge out her eye. The manor itself — which Kaine has charmed against harm to Helena — animates and crushes Aurelia against the wall, saving Helena's life.
Chapter 17: The Order
Helena, blood-soaked, talks Kaine through the alchemical procedure to restore her eye. Days later, Stroud announces Morrough's new plan: Helena must conceive Kaine's child. Helena had been sterilized as a teenager by the Order's healer Maier, on the spiritual head Falcon Matias's insistence, as the condition of her becoming a healer at all. Modern science has made reversal possible. Morrough wants the baby because animancy is heritable.
Chapters 18–19: The Drug
Kaine accepts the order without visible reaction; they begin the coerced sex. Helena feels cold and emptied after every encounter. Stroud gives her a pill designed to suppress resistance; Helena is horrified when her body responds and she physically enjoys what is being done to her. One drunken evening Kaine is suddenly tender, accusatory, mournful — and they kiss.
Chapters 20–21: The Crack
The kiss escalates; Helena tears away and slams her head against the wall in self-disgust. Kaine stops her, tells her she has to live, tells her Luc and the Holdfasts never deserved her. Stroud confirms Helena is pregnant. Helena is so distraught she has to be sedated. Kaine forbids her from harming herself or the pregnancy and stations a necrothrall in her room as a guard. Helena weakens rapidly; Stroud tells Kaine that Helena's resonance is being burned through some unseen drain — the Toll, the divine cost of healing — and that her own erasure may be eating her alive from the inside. Then the dam breaks. Memories pour through: Jan Crowther accusing her of treason, Kaine reproaching her for sleeping with him, friends calling her a traitor. Part One ends on the shatter.
Part Two — The Before Timeline
The long heart of the book. Part Two leaves the manor behind and starts more than two years earlier, in 1785 PD, telling the war story Helena tried to forget.
Chapter 22: Solis Splendour
At Solis Splendour, the Bayard family estate now serving as a Resistance way station, Helena spends a winter evening with Rhea, Titus, Soren, and Lila Bayard, their uncle Sebastian, and Luc, who has been promoted to acting Principate after his father's murder. Helena, as the Order's only true healer, is forbidden from the front. She makes Luc promise to hold on to hope; the Resistance still does not know who the High Necromancer is.
Chapters 23–24: The Heresy
In Februa 1786 Helena recommends to the Resistance Council that they reanimate their war dead to match the Undying's numbers. The Council condemns her for heresy against Orion Holdfast and the Eternal Flame, suspends her, and removes her from the hospital. Soren is the only one who comforts her. Then Ilva Holdfast (Luc's great-aunt and the Council's puppet-master) and Jan Crowther call her to a private meeting: Kaine Ferron has secretly offered to spy for the Resistance, motivated, he claims, by revenge for his mother Enid Ferron's death at Morrough's hands. His price is that Helena — and only Helena — be his liaison. They tell her to seduce him. She agrees, partly to protect Luc.
Chapter 25: The Outpost and the Silver Ring
Helena meets Kaine at an abandoned Outpost. He demands a kiss as proof of her cooperation. His body is wrong — too cold, the wrong texture. He hands her a tarnished silver ring keyed to his own; whenever he needs her, the ring will heat to summon her. (Crowther will later tell her that Kaine's mother was a silver alchemist, and the ring is one of her remaining pieces.)
Chapters 26–28: Training and the Chimaeras
Kaine reads Helena's memories at their next meeting, names the technique animancy, and begins teaching her how to misdirect a mind invasion — she focuses on Luc to hide everything else. Her replacement at the hospital, the agreeable Elain Boyle, fills her old role. Foraging in the wetlands she sees a chimaera, a creature the Order had declared extinct. Her ring burns; she races to Kaine, who is enraged she was alone and unarmed. He insists on training her in combat himself, and a rage-fueled resonance surge nearly demolishes the Outpost.
Chapters 29–31: The Healer in the Forge
Helena reports the chimaeras up the chain. A new orphan trainee healer, Ivy Purnell, joins the hospital. Kaine drills her brutally; Lila confronts her about the bruises and her growing distance from Soren and Luc. Kaine reveals that Morrough is leaving Paladia for Hevgoss, the militocrat-controlled neighbor that has been quietly bankrolling the war.
Chapters 32–34: The Experiments
In Maius 1786 Helena finds Kaine grievously wounded; his arm has refused to regenerate. While he sleeps she sees the lattice of scars across his back — Morrough has been experimenting on him. Tending him in secret, she uses his first name for the first time. Kaine tells her Morrough is hunting the secret of true immortality to deliver to his Hevgoss backers, using the bones of his Undying as fuel. New silver streaks appear in Kaine's hair after each session with Morrough. The Resistance scout Vanya Gettlich dies from lumithium poisoning; the Order dissects her body for clues.
Chapters 35–38: The Stone, the Knives, and the Prisoners
Helena performs Vanya's autopsy and asks Kaine about the mythical Stone of the Heavens — an artifact said to be able to harvest and store souls. Luc confronts her in the lab, demanding to be included in her research; she refuses and he storms out. She and Kaine get drunk together and almost kiss. Back at headquarters, Jan and Ivy task Helena with torturing captured Undying for intelligence. Helena, who once swore an oath to do no harm, complies and is shattered by it; Ivy enjoys it.
Chapters 39–43: The Slow Burn
In Julius 1786 Helena uses Kaine's combat training to survive a necrothrall ambush. By Septembris 1786 the meetings have become refuge. Kaine talks about his mother for the first time. Helena performs alchemical surgery to draw nickel-titanium shards from his torso. She and Shiseo, the foreign metallurgist she has befriended at the lab, design a weapon-grade alloy keyed to her resonance. Then the Undying ambush a Resistance patrol and capture Lila. Luc breaks command protocol to lead the rescue. The Council, livid, accuses him of abandoning his post.
Chapter 44: The Daggers
By Decembris 1786, Kaine's body is so saturated with Morrough's tampering that Helena has to operate to extract alloy fragments. For solstice he gives her a set of nickel-titanium daggers and orders her to wear them always.
Chapter 45: The Truth About Orion
Ilva, finally cornering Helena, confesses the Order's central lie. The Stone of the Heavens is real. It once served the First Necromancer; during a long-ago battle Orion Holdfast either turned it or stole its loyalty, and the Order has lied about its true power for centuries to maintain control. Without the Stone, Luc cannot win the war — and Luc does not know. Helena, furious that she has been used by her own side, promises Ilva she will bind Kaine to the Resistance "by any means necessary."
Chapters 46–48: The First Time
At a solstice party Helena hears whispers that the Council has been spreading rumors she is "ill" to discredit her. Luc tries to reconnect; she refuses, telling him she is no longer the girl he knew, and runs to Kaine in tears. Kaine warns her not to compromise his cover. In Janua 1787, sparring turns into something else, and Helena and Kaine sleep together for the first time. She confesses she is using him; he confesses to a long despair over his mother. She tells Jan, simply, that Kaine will do whatever Jan asks. Jan restricts her to one meeting a week.
Chapters 49–51: Soren
Word arrives that Lila and Soren are gravely wounded and Luc has gone missing. Helena, Jan, a recovered Soren, and Ivy are assigned to find and break open the Undying prison. They locate Luc but the rescue collapses into a battle. Soren takes a blow no living body could survive. Helena tries to reanimate him with the necromancy she has secretly been teaching herself, and partly succeeds — Soren walks them out, but his consciousness is half-gone, and he dies for good before they reach safety. Kaine arrives and saves the survivors. Back at headquarters Luc accuses Helena of necromancy. Sebastian Bayard, present at the scene, quietly confirms it but tells her his brother Soren had asked her to try. The Council buries the truth officially: Soren died "protecting" the rescue. Lila is told her twin was a hero. Helena, hollowed out by Soren's leftover memories that bled into her during the reanimation, finds her only solace in Kaine.
Chapters 52–56: The Two Wars
In Aprilis 1787 Helena tells Kaine she used the sunstone amulet — one piece of the Stone of the Heavens — to heal him; the matching talisman is missing. They promise to protect each other and exchange the rings as emergency summons. Kaine flies her back to headquarters on his alchemized chimaera, Amaris. Ilva and Jan threaten to bar her from headquarters unless she keeps producing. Helena uses animancy to break open Mandl, the warden of the West Island Warehouse where the Undying have been gassing captured Resistance fighters in stasis tanks — a foreshadowing of Helena's own fate. Lila quietly tells Helena that she is pregnant with Luc's child.
Chapters 57–61: Bombs
The Undying deploy nullium bombs that destroy resonance on contact, killing alchemists outright. Helena discovers that obsidian can absorb and trap dark resonance — including the resonance keeping the Undying alive. She begins manufacturing obsidian weapons. While she is dispatched against orders to a field hospital, a nullium blast severely wounds her. She wakes at Spirefell, with Kaine over her and a reanimated necrothrall — Davies, the nurse who raised him — caring for her in his absence. While recovering at Spirefell, Helena realizes she loves Kaine. She does not tell him. She returns to headquarters and forces Jan to give her veto power over Kaine's orders. She secrets a piece of obsidian into Kaine's hand and tells him what it can do.
Chapter 62: The Alliance Falls
Hevgoss formally allies with Morrough. The Council plans an obsidian bomb to be planted in Morrough's West Port Laboratory; Shiseo finishes the device. Helena begs Kaine to run away with her. He kisses her and refuses — Morrough must die first.
Chapter 63: Luc
Helena waits in the medical wing for the bomb to detonate. Headquarters falls instead. Luc is alive — but wrong. He smiles and says, I am Morrough. Morrough has been possessing Luc for months and used him to walk into the Order's last stronghold. The two of them fight; for a moment Luc resurfaces and begs Helena to kill him. She cannot. Luc drives his own blade into himself, and as he is dying, makes Helena promise to look after Lila and the baby. Sebastian is wounded; Luc begs her to revive Sebastian, and she does.
Chapter 64: The Plan
Kaine reveals that he has already rescued Lila and her newborn son and hidden them. Helena reunites with Lila and they sketch out their exit: Helena will personally detonate the obsidian bomb at the West Port Laboratory as a distraction so Kaine can extract her, Lila, and the baby out of Paladia.
Chapter 65: The Capture (End of Part Two)
Helena confronts Ivy, who admits she has been working for the Undying in exchange for the reanimation of her dead sister, Sofia; Ivy is the one who let Morrough's forces into headquarters. Helena triggers the bomb at the West Port Laboratory. Fleeing, she runs straight into Lancaster and his troop and is captured. They drag her before Morrough, where Luc's reanimated corpse and Mandl are waiting. As Morrough begins to claw into her mind, Helena's ring burns — Kaine is hunting for her, but he will not arrive in time. In the seconds she has left, Helena uses her own animancy to erase Kaine, the affair, the bomb, the obsidian, the Stone, and the past three years of her life from her own conscious memory. Mandl, recognizing her, has her gassed and crated into the West Island stasis warehouse. The book's first scene now has a new meaning.
Part Three — The After Timeline
Chapter 66: Remembering
May 1789. Helena wakes at Spirefell screaming and remembers everything. Kaine is at her bedside. He tells her the war ended over a year ago, that Lila and Apollo "Pol" Holdfast (Luc and Lila's son) are alive and safe, that he and Shiseo intercepted Morrough's torture of her at the end of the war, that he has spent fourteen months hunting Resistance fugitives as cover so that he could be the one to find her. He reminds her Morrough has been wearing Luc's bones as the source of his sustained power. Helena's pregnancy — the very thing meant to bind her to the regime — is what shattered her own animantic compulsion.
Chapters 67–69: The Soul, the Baby
The lovers face the central horror. Kaine is one of Morrough's tethered Undying, a piece of Morrough's bone embedded in his arm, his soul partly extracted and stored in Morrough's body as a phylactery. To weaken Morrough enough to kill him, the Resistance plan would require killing every Undying — which means killing Kaine. Kaine has long since accepted that he will die at the end of this war. Helena refuses. They name the baby Enid, after his mother. They sleep together for the first time as full lovers since the war.
Chapters 70–72: Aurelia, Atreus, and Shiseo
Aurelia hosts a dinner where the now-pregnant Helena openly shocks the assembled Undying. Atreus confronts Kaine for letting Morrough use him; the lich-father is no longer fully under Morrough's control. Helena and Kaine begin researching how to retrieve and replace Kaine's stolen soul. Ivy Purnell, of all people, appears at Spirefell to beg forgiveness; she has discovered that Kaine's soul fragment is stored inside one of Morrough's own arm bones and that it can be retrieved. Kaine tries to kill her; Helena intervenes. They send word to Shiseo to bring his metallurgy expertise. Outside, Aurelia ambushes Helena in jealous rage; Kaine alchemically blinds his wife to subdue her. Then the news arrives: Shiseo has been killed in transit, almost certainly on Morrough's orders. The next day Helena and Kaine learn that Atreus has murdered Aurelia — possibly on his own initiative, possibly under Morrough's influence. Kaine, gravely wounded in a confrontation with his father, begs Helena to flee Spirefell.
Chapter 73: Atreus
Helena instead confronts Atreus. She tells him Morrough killed his wife Enid, that Kaine has been Morrough's victim from the start, and begs him to save his only remaining family. Atreus, devastated and lashing out, attacks them both.
Chapter 74: The Ritual
Ivy returns to Spirefell carrying Kaine's phylactery — the bone vessel containing his soul fragment — retrieved from Morrough. Helena designs and lays down a vast new alchemical array. The procedure requires a willing soul as sacrifice to bind Kaine's soul back into a body that has already been hollowed out by years of necromantic stripping. Atreus, having read the memory, offers his. Helena performs the ritual: she unravels Kaine's phylactery, drains the residual life energies Morrough had stockpiled in the Spirefell servants, then unravels Atreus's reliquary and pours his willing soul into Kaine to bind the soul fragment back in place. What remains of Atreus's soul is poured into the corpse of Jan Crowther — reanimated as a vessel — along with what is left of the servants. The Spirefell estate burns around them. Kaine emerges alive but transformed: silver-white hair, pallid grey eyes, mortal again but caught between systems. He, Helena, and the pieces they can save fly out on Amaris as Spirefell collapses.
Chapters 75–77: The Island
Kaine and Helena take refuge in a hunting cottage, then a village, where they reunite with Lila and Pol. The High Reeve's disappearance has reignited fighting in Paladia. The whole group sails to a remote island off the coast of Etras, Helena's birth-country. There, in a cottage Kaine had quietly prepared years earlier as an escape route, Helena gives birth to Enid Rose Ferron. Amaris finds them. Lila, refusing to let the Resistance and its dead be forgotten under the Undying's official history, decides to return to Paladia and finish what Helena started. Kaine teaches her hand-to-hand combat; Helena builds her a final, more powerful obsidian bomb. Lila and Pol go back to Paladia, and roughly a year and a half later, Lila Bayard kills Morrough, becoming the public face of the war's end. She invites Helena and Kaine home; they decline. Years pass on the island, and Helena slowly notices that Kaine has been quietly killing people from their past — Stroud most prominently — to scrub away the evidence. Helena is furious that he is still making her decisions for her in moral darkness. She forgives him. Enid grows up.
Epilogue: The Caption
Julius 1808. Enid Rose Ferron, now grown, arrives in a rebuilt Paladia by river ferry to study vivimancy at the restored Alchemy Institute. She is met at the dock by Lila Bayard and Lila's son Pol (Apollo) Holdfast, who has been accepted alongside her — the next generation, exactly mirroring their parents. Wandering into a Paladia bookstore, Enid picks up a brand-new tome: A Comprehensive History of the Paladian Necromancy War by William Dover, with a foreword pulling from Eustace Sederis's Ferron: A Biography of the High Reeve. Sederis describes Kaine as a monster long before Morrough ever reached Paladia and a born psychopath, credited with murdering Apollo Holdfast at sixteen and rising to become the youngest of the Undying generals. Enid turns the page and finds a photograph of her mother standing between Luc Holdfast and Soren Bayard at a long-ago solstice. The caption reads, in part, that Helena Marino was a non-active member of the Order of the Eternal Flame and did not fight, an Etras-born foreign alchemist who left the city at the war's start to study healing.
That is how history records the woman who served as the Resistance's secret animancer, who healed Luc and the Bayards through years of war, who restored Kaine's stolen soul, who built the obsidian weapons that ended the Undying, and who erased her own mind to keep her lover alive. Enid closes the book. Pol approaches, grinning crookedly. The novel ends on that line — and the implicit promise that the next generation, knowing the truth, will rewrite the record.
Themes the Recap Doesn't Spell Out
Memory as the contested terrain
Helena's animancy is power, but the book's deepest cruelty is that the world gets to do to her what she did to her own mind — erase her, edit her, render her a footnote. The ending mirrors the beginning.
The cost of survival
Both leads carry permanent disfigurement of body, mind, and conscience. The Toll is not metaphorical: every act of healing in Paladia demands a payment, and the book is honest about who pays.
Two fascisms
The Order of the Eternal Flame and the Undying are not equivalents, but the Order's purity politics — sterilization of "impure" alchemists like Helena, suppression of vivimancy and animancy, the Holdfast family's centuries-long lie about the Stone of the Heavens — is treated with as much suspicion as Morrough's necromancy.
The fanfic DNA
Alchemised is built on the bones of SenLinYu's hugely popular Manacled — a Hermione/Draco crossover with The Handmaid's Tale — but the world, magic system, religious structure, and political ideology are original. Some character mappings are still legible (Helena to Hermione, Kaine to Draco, Luc to Harry, Lila to Ginny, the Bayards to the Weasleys, Morrough to Voldemort, Mandl to Umbridge, Atreus to Lucius, Shiseo to Snape), but the political and theological backdrop is its own thing.
About the Book
Alchemised is SenLinYu's debut novel, published September 23, 2025 by Del Rey in North America and by Michael Joseph (a Penguin imprint) in the UK, Australia, and New Zealand. The deluxe Del Rey hardcover runs roughly 1,024 pages with cover art by Eva Eller and a black-and-white interior illustration by Avendell, who illustrated Manacled. The Saskia Maarleveld-narrated audiobook runs about forty hours.
The novel began life as Manacled, SenLinYu's enormously popular Harry Potter "Dramione" fanfiction (Hermione/Draco) layered with elements of The Handmaid's Tale, published serially on Archive of Our Own between April 2018 and August 2019. Manacled accrued over 10 million hits on AO3 — making it one of the most-read works in Harry Potter fandom history — before being voluntarily removed from the platform on January 1, 2025 in advance of Alchemised's publication. SenLinYu has said the original was reworked into an original novel partly because of unauthorized monetization of Manacled by third parties; the IP and intellectual scaffolding of Harry Potter and The Handmaid's Tale were stripped out and replaced with the original Paladian world, the resonance magic system, and a substantially expanded political and religious backdrop.
Del Rey acquired the book from SenLinYu in a two-book deal in February 2024. It released with an initial U.S. print run of 750,000 copies, was Penguin's most pre-ordered debut of 2025, and was translated into 21 languages on launch. Alchemised debuted at #1 on the New York Times combined print and e-book bestseller list (where it stayed for 15 consecutive weeks), as well as the USA Today, Los Angeles Times, and Indie bestseller lists, selling around 300,000 copies in North America in its first week. Penguin Random House now markets the book as having sold over one million copies. It won the 2025 Goodreads Choice Award for Readers' Favourite Debut Novel and was the runner-up for Readers' Favourite Romantasy.
Film rights were acquired by Legendary Entertainment on September 10, 2025 — nearly two weeks before publication — in a pre-emptive deal The Hollywood Reporter described as exceeding $3 million, reported by industry trades as one of the most expensive book-to-screen rights acquisitions in recent memory (not adjusted for inflation).
SenLinYu lives in Portland, Oregon, and started writing what would become Manacled in the Notes app of their phone during their baby's naps. Alchemised is the first book in a two-book deal with Del Rey; no direct sequel has been announced, though the open-ended epilogue and the Legendary deal leave clear room for follow-ups in the world of Paladia.
