Rise of a Queen opens with a prologue set 22 years before the main events. Jonathan King, attending his mother Anna's funeral, sits apart from the mourners with his best friend, Ethan Steel, plotting to destroy Lord Sterling, the aristocrat who has attacked the King family's business out of spite over Anna's rejection. At the cemetery, Jonathan encounters a girl of about five named Claire comforting her older half-sister Alicia Sterling at the grave of their mother, Lady Bridget Sterling, and realizes the girls are connected to his enemy. When Lord Sterling taunts Jonathan's father, Gregory, threatening to seize the family home, Gregory collapses from cardiac arrest and dies. Jonathan vows to eradicate everything Sterling cares about.
In the present day, Jonathan returns home to find that Aurora Harper, the woman living with him under a six-month arrangement, has not come home. Harris, Jonathan's COO, reports that Maxim Griffin, a serial killer known as the "Duct Tape Killer," has given a public interview accusing his daughter Clarissa of being his accomplice. Jonathan realizes Aurora's real identity is Clarissa Griffin, who reported her father to police at 16, and that she fled after seeing the interview.
Aurora, reeling from the broadcast, a physical attack by a victim's family member, and a voice recording from her dead sister Alicia warning that Jonathan is poisoning her, drives to her father's old hunting cottage in Yorkshire, where Maxim buried seven victims. She visits each grave, apologizing by name, and discovers the eighth grave, previously empty, has been reopened. A masked figure attacks her and knocks her into the open grave. A flashback reveals that at 16, a masked man with a dragon tattoo stabbed her at this same site; she crawled out and sutured the wound herself, leaving a scar and closed-eye tattoo on her side.
Jonathan flies to Leeds and reaches the cottage with Moses, his driver and security man. A figure leaning over the grave escapes when Moses gives chase. Jonathan carries Aurora out, unconscious and bloodied, and signals his willingness to use criminal networks to find her attacker.
Aurora wakes at the King mansion, where Jonathan has tended her wounds. When Alicia's recorded warning floods back, Aurora becomes convinced Jonathan killed her sister. She attempts to escape using a bedsheet rope from the balcony, but Jonathan catches her, locks her in her room, and stations guards outside.
Their standoff escalates. Jonathan tends to Aurora with clinical gentleness, but she refuses to speak. In desperation, she arms herself with a glass shard and, in a struggle, cuts his throat. Horrified, she breaks down. Jonathan comforts her, insisting she is nothing like her father. Aurora finally whispers her accusation: He killed her sister.
She reveals the flash drives containing Alicia's recorded claims of being poisoned, but when Jonathan sends Moses to retrieve them, they have vanished. Her former concierge denies receiving any packages. Jonathan regards her with pity, and Aurora cries alone, insisting she is not losing touch with reality.
Jonathan explains that he married Alicia as revenge against Lord Sterling, though Alicia agreed because she wanted to bring down her own father for driving Bridget to suicide. He describes Alicia as having experienced worsening hallucinations and paranoia, insists he never poisoned her, and resolves not to repeat his emotional failures with Aurora.
Aurora visits Aiden, Jonathan's son, and Elsa, Aiden's wife, at their home in Oxford. Aiden confirms his mother experienced episodes and tells Aurora that Jonathan never looked at Alicia the way he looks at Aurora. Jonathan tracks Aurora to Oxford, and during dinner, Aurora nudges him to compliment Aiden's cooking, a small gesture that begins mending their father-son relationship.
Jonathan hires Kyle, a former Russian mafia operative introduced through Tristan Rhodes, a duke with connections to criminal networks, to track Aurora's attacker. Separately, Ethan approaches Aurora and reveals his complicated history with Jonathan, including a falling out over a factory fire Jonathan orchestrated, which prompted Ethan to kidnap young Aiden in retaliation.
At a gas station, Aurora sees a broadcast announcing Maxim's approved parole hearing and an investigation into Clarissa Griffin. Her photograph and current identity appear on screen. Jonathan flies her to his private island to shield her from the media. He arranges protection for Layla, Aurora's closest friend and business partner at their watch company, H&H, after Aurora reveals her true identity. Layla accepts without judgment.
On the island, they reconnect. Aurora confesses her fear of sharing Maxim's violent nature because she enjoyed hunting with him as a child; Jonathan insists that reporting her father proved her fundamental decency. Aurora reveals she cannot have biological children due to a genetic condition. Jonathan accepts this, calling her his queen for the first time. Aurora decides to return to England, declaring she is done running.
Aurora voluntarily submits to prosecution questioning, denying involvement in Maxim's crimes. Outside, hostile protesters and press swarm her. Jonathan arrives and publicly announces Aurora is his fiancée, stunning her. When Aurora later references their arrangement's approaching end date, Jonathan withdraws for a week. She provokes him by inviting Ethan to the mansion; Jonathan responds with a possessive kiss and declares he will not let her go.
A pivotal revelation arrives when Aurora receives a recording from Maxim's solicitor. The recording captures Maxim at the scene of Alicia's fatal car accident, where dying Alicia reveals that Bridget became Maxim's original "muse," the person whose resemblance Maxim sought in his victims. This confirms Aurora's earlier messages from Alicia were real. Aurora then visits Maxim in prison, refuses to apologize for turning him in, and bids him a permanent farewell, feeling free of his shadow for the first time.
Returning to the King mansion, Aurora is ambushed and drugged with propofol. She wakes tied to a chair, facing Margot, the housekeeper, and Tom, the butler, whom she recognizes as her attacker from 11 years earlier by his dragon tattoo. Margot reveals her sister Megan was Maxim's first victim, a murder dismissed as a drug overdose. She and her nephew Tom infiltrated the household to destroy Maxim's "muses," destabilizing Alicia's mental health through gaslighting: planting whispered recordings, moving objects, and slipping substances into her food. They also sent Aurora the flash drives. Tom holds a knife to Aurora's throat as Margot records the scene to broadcast to Maxim.
Jonathan, warned by Kyle, races home and stalls by threatening Tom's imprisoned father, Shelby. Kyle shoots Tom through the kitchen window, and Margot is arrested.
In the aftermath, Shelby attacks Maxim in prison, leaving him comatose, and the parole case collapses. Aurora shares a portion of Alicia's final recording with Aiden, giving him closure. Jonathan transfers full ownership of H&H's stocks to Aurora and Layla, wanting Aurora to stay by choice rather than obligation. Aurora tells Jonathan she loves him and is staying, referencing a childhood memory in which Alicia gave her permission to marry him someday.
In the first epilogue, set six months later, they marry on the island, which Jonathan has renamed after Aurora. Ethan walks her down the aisle. In the second epilogue, three years later, the couple vacations on their island, content in their child-free marriage. Jonathan has begun ceding control of King Enterprises to Aiden. The novel closes with Jonathan carrying Aurora into the ocean, their relationship grounded in mutual love rather than coercion.
