Liv Green is a 42-year-old cleaner and mother of two who juggles three jobs to support her family. She works mornings at Platinum, an accountancy firm; middays for a wealthy family called the Cardinals; and afternoons for Essie Starling, a reclusive bestselling novelist who has not appeared publicly since winning the Constellation Writing Prize, a prestigious literary award, a decade earlier. Essie is the creator of Georgia Rory, a beloved adventurous heroine whose 19-novel series has captivated readers since the late 1980s.
One afternoon, while tidying Essie's penthouse apartment, Liv discovers handwritten pages labeled "Book Twenty," the latest Georgia Rory manuscript. Essie catches her reading but, instead of firing her, shows Liv a harsh review of her most recent novel,
Few and Far Between, and asks for an honest opinion. Liv admits she feels Essie has lost her passion for Georgia Rory. Essie proposes that Liv take on extra tasks to help revitalize the character, and Liv agrees eagerly. Days later, Essie vanishes. Anthony Pentecost, Essie's solicitor, meets Liv and delivers devastating news: Essie went into hospital for an operation related to chronic pancreatitis, developed a fatal infection, and died on May 1.
Anthony reads from Essie's yellow notebook: Liv must keep the death secret for six months, until November 1, and complete the final novel during that time. The funeral is a private affair registered under Essie's real name, Elsbeth Smart, which helps conceal the death. When Liv examines the manuscript, she discovers it ends at chapter 32 of the expected 40. The missing final eight chapters, where Georgia typically overcomes her greatest challenges and finds love, do not exist. Under Essie's pillow, Liv finds gold bee-shaped cuff links.
Liv's husband, Jake, runs Paperpress, a struggling family printing business that has absorbed most of their savings. Their sons, Mack and Johnny, are both university-age, and finances are tight. Liv left school at 16 to support her mother, Carol, after the death of her father, Grant Cooper, an English professor killed in an accident when Liv was young. The extra pay is money the family needs, and Liv feels she cannot refuse Essie's dying wish.
Reading the full manuscript, Liv finds Georgia's warm persona replaced with bitterness. In the margins, Essie has scrawled: "Who is the love of Georgia's life?" Liv studies photographs of Essie's two ex-husbands: Ted Mason, a publishing mogul, and Hank Milligan, an American crime writer. She discovers a hidden photo of a tattooed blond man. Matilda, Essie's former personal assistant, reveals Essie once confessed she could not finish her book without "the only man she ever loved." Watching footage of the Constellation Prize ceremony, Liv hears Essie thank "someone very special" and notes the ceremony took place on November 1. In dark after-party footage, she glimpses something disturbing and stops watching after 10 minutes.
Realizing she cannot manage the task alongside her other jobs, Liv negotiates a full-time salary and quits her cleaning positions. She throws herself into rewriting, discovering that wearing clothes from Essie's wardrobe helps her channel Georgia's spirit. Tensions with Jake intensify as he questions her new role and dismisses Essie's writing.
Complications arise when Chloe Anderton, a journalist from
Sheen magazine, begins investigating the reclusive author. To protect the secret, Liv impersonates a journalist's assistant to reach Ted before Chloe can. Ted describes marrying young Essie but admits she never fully loved him. Chloe later infiltrates the apartment and discovers two different handwritings in the manuscripts. Liv strikes a deal: quotes from Hank and a book excerpt in exchange for Chloe delaying publication until November 1 and refocusing the article on Georgia Rory's fans.
When Essie's publisher invites the author to the Dubrovnik Book Festival, Liv travels alone and poses as Essie's representative, drawing on her encyclopedic knowledge to impress foreign editors. Essie's agent, Marlon, reads Liv's rewritten chapters and says the writing is "fresher," as if Essie is "falling in love with Georgia again." In Dubrovnik, Liv tracks down Sven, Essie's former literary agent and the tattooed man from the hidden photo. Sven reveals he was never Essie's lover and that Essie told him there was "only ever one man who could hold her attention."
To reach Hank, Liv disguises herself as Essie and attends the opening of his new UK bar. Hank reveals he cheated on Essie, and the other woman became pregnant, a painful blow since the couple had long struggled to have children. A journalist broke the news to Essie at the Constellation after-party. Essie refused to return to LA, divorced Hank, and withdrew from public life. Anthony, meanwhile, confesses he fell in love with Essie at university when they were both 18 but that she never loved him back.
As her marriage buckles under secrets and absences, Liv completes a draft with a new love interest named Frank. But Frank is a soulless composite modeled on the men in Essie's life, and Liv knows the ending fails Georgia. Then Anthony drops a bombshell: Grant Cooper, Liv's father, was Essie's English professor and the only man she ever truly loved. Essie chose Liv because she was Grant's daughter.
Enraged, Liv watches the full after-party video she abandoned months earlier. A devastated Essie screams as security escorts her out: "I only ever loved one man and he's dead. Grant, I'm so sorry." Using a brass key Essie left her, Liv enters a secret student flat near the university. There she finds Essie's letter confessing everything: Essie loved Grant, though the relationship never became physical. When Grant chose Carol over Essie's publication party for
The Moon on the Water, Essie caused a scene that made him late, and she blamed herself for his death. Essie recognized Liv from a fan letter mentioning Grant's name and hired her to be close to his daughter. Grant's letters confirm he rejected Essie kindly. In one, he asks Essie to encourage Liv's writing if they ever meet. His final letter, dated November 1, 1989, tells Essie their relationship must end.
Liv stays at the flat for days, processing grief. Jake visits daily with food, sitting quietly without pressuring her. Their connection slowly rekindles. With seven days left, Liv deletes the last eight chapters and rewrites them. She stops trying to write like Essie and crafts an ending where Georgia chooses not to ride off with a hero but to find herself. When Liv types "The End," she cries but feels lighter than she has in months. On the night before November 1, Liv tells Carol everything. Carol reveals she always suspected Grant had grown close to a student and once found the bee cuff links in his sock drawer.
On November 1, Liv submits the manuscript, and Essie's death is publicly announced. Fans gather outside bookshops worldwide. Chloe publishes her article celebrating Georgia Rory's impact. At a memorial tea party, the key figures from Essie's life gather. Meg, Essie's editor, tells Liv the manuscript is the best thing Essie ever wrote. Anthony reveals Essie's notebook requested Liv receive a co-credit on the cover, but Liv declines, asking to be named only in the acknowledgments.
Weeks later, Liv visits the empty apartment one final time, vacuuming carpets and wiping surfaces with her homemade lavender solution. She whispers goodbye in the writing room. Jake meets her outside, and they walk through fresh snow toward the museum. Liv looks up at the white sky, seeing it "like a blank page of paper waiting to be written upon."
