Tilly arrives at Book Lane, immediately confronted by the familiar sensory experience of a bookshop but feeling out of place. At the counter, she meets Alfie, a man with scruffy facial hair who looks younger than his gravelly voice suggests. A tabby cat purrs on the counter beside him.

Alfie explains that Joe came to the shop a year ago to place an unusual order: If he hadn’t returned by Christmas, Alfie was to call Tilly on January 5th. He offers his condolences and wishes her happy birthday before presenting her with a brown-paper-wrapped book tied with ribbon—the first of 12 books, one for each month of the year, Joe’s gift to her.

When Tilly demands all 12 books immediately, Alfie refuses, explaining that Joe wanted her to receive one book per month. Frustrated and upset, Tilly shouts that Joe is dead. Alfie repeats that he made a promise. Tilly snatches the parcel and storms out.

At her cottage, surrounded by Joe’s belongings, Tilly reflects on being stuck in grief six months after his death. Unable to resist, she opens the parcel.

The narrative flashes back to the day Tilly and Joe met in Foyles bookshop at Charing Cross. They collide while browsing, and Joe, an American, asks about the book she’s holding. She recommends starting with Fredrik Backman’s A Man Called Ove (2012) and offers to show him where to find it.

As they walk through the store, he learns she’s from Hay-on-Wye and works in publishing, editing celebrity memoirs. Her favorite book is Madeline; she loves that the protagonist has red hair like hers but feels they are otherwise completely different—Madeline is so feisty and brave. Before asking for her number, Joe confesses he doesn’t read and only entered the shop to escape the rain. Tilly decides it’s time for a change from her usual reader boyfriends and agrees to see him again.

In the present, Tilly unwraps the parcel to reveal Roald Dahl’s Matilda (1988). Inside is a handwritten letter from Joe wishing her happy birthday and explaining the “year-of-books” gift. He hopes the books will help her start reading again, as she stopped when he was diagnosed. He chose Matilda to remind her how and why she became a reader and to make her smile. Tilly speaks to Joe’s blue ceramic urn on the bookshelf, saying that reading is no longer who she is. She places the book on the coffee table, where it remains unread for weeks.

On February 1st, Alfie deals with a difficult customer while watching the door for Tilly, whose next book waits on the collection shelf. She doesn’t arrive all day.

That evening, Alfie visits his mother, Emylia, and helps her hang pictures before his stepfather, Andrew, returns from a work trip. Over takeaway and TV, he reflects on how she dislikes being alone in the evenings. His thoughts drift to Tilly and to Joe Carter’s visit a year ago, when the pale, unwell man placed his unusual order. Alfie worries about his promise—what if Tilly never returns?

At Splash Books, where Tilly works, she is distracted during an editorial meeting. Her boss, Sade, announces a major new project: the memoir of social media influencer Esmerelda Love, with Tilly as editor. Esmerelda needs a ghostwriter, and Sade suggests Rachel Harding, an experienced professional and Tilly’s old friend.

Tilly sends Rachel a brief, professional email about the opportunity. Rachel replies enthusiastically, suggesting they meet up and mentioning that she’s missed their pub nights. Tilly replies professionally, ignoring the personal invitation. She recalls their friendship at work and how they used to meet regularly to talk shop and swap books. Sade praises Tilly’s work and hints at a promotion, but Tilly feels uneasy about working with Rachel and is sad that Joe isn’t there to share her success. She thinks of the unread Matilda and the uncollected February book, feeling that she doesn’t deserve another one.

Later, Tilly is at home when her younger sister, Harper, arrives with Thai takeaway, wearing a sweater Tilly knitted while Joe was in the hospital. Harper has just returned from a work trip to Thailand for the luxury travel magazine Voyageur. Tilly tells Harper about Joe’s year-of-books gift. Harper encourages her to read Matilda, calling her inability to read a “reading slump,” but Tilly insists it’s more than that. Harper points to the clutter of Joe’s belongings and offers to help clear them, but Tilly refuses. While Harper is in the bathroom, Tilly talks to Joe’s urn, but Harper comes out unexpectedly and catches her doing it.

Harper suggests going out, but Tilly declines. Harper leaves to join friends at a party. Tilly’s mother-in-law, Ellen Carter, calls and leaves a voicemail. The call triggers a memory of visiting Ellen and Hank in Connecticut when Tilly and Joe were dating. Tilly remembers overhearing Ellen telling Joe that Tilly seemed too bookish and wasn’t a joiner like their family, questioning whether she was right for him. Joe had defended Tilly, saying she was perfect.

Feeling too tired to work, Tilly finally picks up Matilda. As rain hammers on the windows, she begins to read. The world beyond the pages disappears, and she reads through the night without moving. The experience feels transformative, as if a locked door inside her has finally opened.

On Saturday morning, Tilly visits the Primrose Hill Community Library and heads to the children’s section. She finished Matilda overnight, captivated by how the story was funnier and darker than she remembered. She selects several childhood favorites and crawls into a house in the children’s corner to read. When a little girl sees her crying inside and tells her mother, Tilly emerges, embarrassed.

She encounters Alfie, who is donating unsellable stock from the bookshop. He reminds Tilly that her February book is waiting. He mentions that Dr. Seuss’s Green Eggs and Ham (1960), one of the books she was reading, is a favorite of his. Realizing she’s curious about what Joe chose next, Tilly agrees to return to Book Lane with him.

As they walk to the bookshop, Tilly apologizes for her angry behavior during her last visit. Alfie reassures her, saying it “must have been a shock” and shares that his own father died seven years ago (46). They agree on the inadequacy of the phrase “I’m sorry.”

At the shop, Alfie introduces Tilly to his colleagues: Prudence and Blue. Prudence gives Tilly a warm, comforting hug. Alfie retrieves the February book—a heavy parcel wrapped in brown paper and tied with a purple ribbon. Tilly tells him she enjoyed Matilda, and Alfie admits that he rereads C. S. Lewis’s The Lion, the Witch and the Wardrobe (1950) every Christmas for comfort. Tilly thanks him and says she’s glad she came back. As she leaves, Alfie watches her go, wondering how she will react to the next book.

In her kitchen, Tilly stands surrounded by ingredients and Joe’s new book, Delia’s Complete How to Cook (2009) by Delia Smith. In his second letter, Joe gently teases her about her cooking—referencing a disastrous lemon meringue pie incident—and encourages her to take care of herself by making comforting meals. He suggests the Souffléd Macaroni Cheese and invites her to share meals with others, reminding her she’s not alone.

Tilly speaks to Joe’s urn, recalling how she set the tablecloth on fire while blowtorching the meringue and how Joe calmly extinguished it with water. As she cooks, she puts on music, and the flat fills with the smell of cheese. While browsing the cookbook, she finds a pumpkin pie recipe that triggers a painful memory of a Thanksgiving argument with Ellen.

The macaroni and cheese turns out well, and as she eats, she imagines Joe teasing her and calling her Mouse. The taste triggers a vivid flashback to an evening years ago when Joe canceled their plans to build her a reading den. He made his mother’s macaroni and cheese recipe, his ultimate childhood comfort food. In the present, Tilly rearranges her furniture to build a makeshift den for herself and crawls inside to finish her dinner, acknowledging that sometimes you have to build your own fort.

On a morning in early March, Alfie sees Tilly at the shop window before he opens, hoping to collect her next book before work. Inside, she instinctively rearranges a book display to feature a memoir she edited, explaining it’s a bad habit from her job in publishing.

Georgette winds herself affectionately around Tilly’s legs. Tilly mentions her husband always wanted a dog. Alfie remarks that cats and book lovers are similar—both enjoy indoors, sunny spots, snacks, and quiet time. They playfully list books featuring cats, from Turman Capote’s Breakfast at Tiffany’s (1958) to Dr. Seuss’s The Cat in the Hat (1957). Tilly gives Alfie a slice of homemade coffee and walnut cake she baked from her new cookbook.

He hands her the March book wrapped in pink ribbon, and Tilly opens it immediately. The book is Beach Read (2020) by Emily Henry, a romance. Tilly hesitates, saying she doesn’t believe in happily-ever-afters anymore. Alfie passionately defends it as the perfect romantic comedy. He suggests that fiction can be an escape from reality. Inside the book, Tilly finds a letter from Joe. As she reads, her expression changes to shock and disbelief.

Joe’s letter reveals that although they weren’t able to go on their honeymoon to Bali, he didn’t cancel it—he rescheduled it for March 12th. He has arranged for Tilly and Harper to go, knowing Tilly needs a holiday. Tilly thinks she can’t go with such short notice due to work, but her boss, Sade, reveals that Joe contacted the office a year ago to arrange Tilly’s time off. Sade praises Tilly’s work and tells her to enjoy the trip. At her desk, Tilly looks at photos of Bali before being interrupted by an email from Esmerelda, demanding organic California almonds for their meeting.

Tilly meets Rachel outside a nail salon in Richmond before they meet with Esmerelda. They share an awkward hug. Inside, Esmerelda is having a manicure and pedicure. She demands the almonds, but her nails are wet, so she expects Tilly to feed them to her. To keep the peace, Tilly complies. The act triggers a painful memory of spoon-feeding Joe in the hospital.

After the meeting, Rachel invites Tilly for coffee, but Tilly makes an excuse. Rachel gives Tilly a battered copy of Gabrielle Zevin’s Tomorrow, and Tomorrow, and Tomorrow (2022), saying she loved it. As Rachel walks away, Tilly acknowledges to herself that, despite everything, she misses their friendship.

Tilly meets Harper at Heathrow Airport, wearing the large sun hat Joe liked. At an airport bar, Harper looks at the resort’s Instagram page while Tilly checks work emails. She sees an exchange where Esmerelda suggests writing her memoir in rhyme and Rachel’s witty, rhyming rejection, which makes Tilly laugh. They exchange a few friendly emails about the difficult client and Tilly’s upcoming holiday.

Harper takes Tilly’s phone and declares the holiday officially started. When Tilly returns from buying drinks, Harper is frowning at her phone. Harper claims she’s just texting her boyfriend, Raj, but seems evasive when Tilly asks if he’s okay. Their gate is called, and Tilly prepares to leave for Bali.

On their second night in Bali, Tilly and Harper are at a beach bar. Harper takes photos of them for her work social media. She says she’s proud of Tilly for not working, but Tilly points out that Harper is working.

Harper says it’s different because she enjoys her job. She questions whether Tilly still enjoys hers, reminding her that it was meant to be temporary before moving into fiction editing. She points out an attractive man and suggests a holiday fling might help Tilly move on. Tilly becomes upset, but after a tense silence, Tilly asks about the next part of their evening plan, trying to move past the moment.

At a karaoke bar, Tilly initially refuses to sing, but Harper reminds her that she’s always loved karaoke. She persuades Tilly to sing one song.

Tilly chooses Sinéad O’Connor’s “Nothing Compares 2 U,” intending it as an ironic joke, but she is painfully reminded of Joe. Unable to finish, she stumbles off stage and runs onto the beach. Harper follows, and Tilly shouts at her to just let her be sad. Harper apologizes and hugs Tilly tightly. Tilly resists, then collapses into the embrace.

Harper apologizes for pushing her, and after sitting in silence for a while, Tilly suggests they go back for another song. This time, they take the stage together and sing “We Are Family” by Sister Sledge. A group of women joins them on stage. Dancing and singing together beneath the glowing lanterns and glittering disco ball, Tilly feels a moment of joy.

The next morning, Tilly goes to the resort library alone and settles in to read Beach Read, determined to give it a proper chance. Hours later, Harper joins her. Tilly is almost halfway through the book and feels irritated at the interruption. Reading again reminds Tilly of why she wanted to work in publishing—to discover new authors and put meaningful stories into the world. She realizes Harper was right that she has forgotten how to dream.

Harper announces that she has booked them a surfing lesson. On the way to the pool, Tilly stops at a gift shop to buy postcards. She writes one to her parents and begins a second. She realizes that it is time to start making decisions about her future. During the surfing lesson, Tilly falls off her board repeatedly while Harper sails by like a pro, but each time Tilly falls, she pulls herself back up again.

Alfie attends his niece, Mia’s, seventh birthday party at his sister, Tash, and brother-in-law, Stu’s, Surrey home. Stu condescendingly questions the viability of independent bookstores and offers Alfie a job at his office supply company. Alfie gives Mia a book, which she greets with a sigh, and Tash reminisces about their father reading the same book to her as a child.

While washing up, Tash apologizes for Stu’s behavior and says their father would be proud of Alfie for keeping the shop going. A plate slips from Alfie’s hands and smashes. Tash encourages Alfie not to forget about his own life, mentioning a past girlfriend named Freya, and telling him he would be a brilliant father.

A few days later, at the shop, Alfie receives a postcard from Tilly in Bali. She writes that she’s loving Beach Read and will need more recommendations. Alfie pins it to the notice board and smiles. When he opens the next letter in the stack of post, his smile vanishes.

Tilly returns from her holiday and turns on her work phone. She is bombarded with increasingly irate voicemails and emails from Esmerelda Love, the final one ending with Esmerelda screaming at her. Deciding she has had enough, Tilly tosses her work phone into her empty suitcase, makes tea, and continues reading her book.
