The group reconvenes to make pesto, and Tilly notices Harper taking out her tension on the pasta dough. As they set the dinner table, Tilly pours wine for everyone, giving Harper an especially generous glass. She glimpses Harper’s phone and sees her scrolling through a dating app. Harper quickly hides the phone when she notices Tilly looking.

During dinner, newlyweds Tiff and Tim discuss their recent wedding and ask if Tilly and Harper are married. Tilly realizes she forgot to put her wedding ring back on after the pasta-making session. Seeing Harper’s strained expression, she replies that they are not married and redirects the conversation. Throughout the meal, Tilly observes signs that something is clearly wrong with her sister.

On the morning of Joe’s death anniversary, Tilly wakes from a nightmare about fighting with him and goes for a run. She realizes the dream was actually a memory from Thanksgiving dinner at Joe’s parents’ house in Connecticut. During that visit, Joe announced their engagement, and his mother Ellen reacted poorly before feigning happiness. Ellen pressed Tilly about keeping her surname and having children, then asked where they planned to raise a family. Joe said America at the same moment that Tilly said London, revealing a fundamental conflict that they had never discussed.

Resting on a stone wall, Tilly speaks to Joe aloud. She recalls how shocked they both were to discover their differing assumptions and how they fought for months afterward. Then Joe got sick, and their focus shifted entirely to his health. Crying, Tilly wishes she could tell Joe she would have moved anywhere for him. She resumes her jog, knowing she can only move forward.

Back in the pasta class, Tilly is distracted and clumsy. After she drops a second egg, the instructor Constanza leads her to a quiet terrace and asks what is wrong. Tilly confesses it is the first anniversary of her husband’s death. Constanza reveals that she is also a widow—her husband Marco died 10 years ago—and shows Tilly his wedding ring, which she still wears. She tells Tilly that grief is a “gift,” and while sadness remains, happiness is also possible. Tilly feels a sense of peace.

That evening at dinner, Tilly opens up to the group about Joe, prompting others to share stories of their own lost loved ones. A sudden thunderstorm breaks, and everyone rushes inside. Tilly remains outside for a moment, letting the rain fall on her, feeling as if something is being washed away.

Unable to sleep after the storm, Tilly decides to check on Harper. Finding her room empty, she follows Harper’s voice to a moonlit courtyard. Her sister is on the phone, saying she promised to tell Tilly something but isn’t going to do it today. Harper spots Tilly and hangs up. Tilly assumes that Harper has broken up with Raj and says she knows about them. Harper, misunderstanding, expresses relief. She then reveals they have not broken up—they are getting married and have been engaged for a year.

Tilly is stunned and hurt that everyone else must know. She then confronts Harper about seeing her on a dating app. Harper confesses that she secretly created a dating profile for Tilly and has been messaging men on her behalf. Furious, Tilly demands to see the profile and discovers that Harper cropped Joe out of her profile photo. She accuses Harper of being disrespectful and impersonating her online. Tilly throws the phone at Harper, tells her not to follow her, and walks away.

Two weeks later, Tilly has not spoken to Harper since leaving Tuscany early. At Book Lane, she tells Alfie about the fight. She expresses nervousness about her upcoming visit to see Joe’s parents in Connecticut but looks forward to spending a few days in New York afterward.

At home, Tilly opens her August book to find Letter from New York (1992) by Helene Hanff. Joe’s letter reminisces about their first trip to New York together, revealing that it was there, at the top of the Empire State Building, that he decided he would one day propose. He wonders if she will ever return to New York and asks that if she does see his parents, she give them both hugs from him. Tilly hugs the book and letter, her eyes drawn to Joe’s urn on the bookshelf.

Tilly arrives at Ellen and Hank’s lakeside house in Connecticut. Hank greets her warmly, while Ellen is reserved. The family’s golden retrievers break the initial tension. Ellen puts Tilly in a different guest room, not the one she used to share with Joe. Over dinner, conversation is polite and avoids difficult topics.

That night, Tilly finds Ellen sitting on Joe’s childhood bed, crying over a photograph. After a tense start, a shared memory of Joe and a joke from Ellen break the ice between them. Ellen apologizes for her past behavior, explaining that she struggled with the thought of her son and future grandchildren living so far away. Moved, Tilly sits with her and confesses she had been willing to move to America for Joe. She reveals that she was offered a job in New York on the same day Joe was diagnosed with cancer, so she never told him. Overwhelmed by the memory, Tilly breaks down. Ellen takes her hand and says there is something Tilly needs to know.

Ellen reveals that a few weeks before his diagnosis, Joe called her and said he had decided to build his life with Tilly in the UK because he didn’t want to uproot her from her career. Tilly is devastated by the revelation that they were both willing to move for each other but never knew it. Ellen tells Tilly that Joe was truly happy with her. The two women embrace, and Tilly gives Hank his hug from Joe the next morning.

On Joe’s birthday, the family goes out on the lake. In the middle of the water, Tilly takes out Joe’s urn. At Ellen’s prompting, she recites the poem “Do Not Stand at My Grave and Weep” from memory. On the morning of her departure, Ellen tells Tilly that she is always welcome and part of the family. She encourages Tilly to live her life fully and make new memories.

Tilly arrives in New York City. After checking into the Library Hotel, she visits the New York Public Library and begins exchanging direct messages with Alfie through the Book Lane Instagram account, sending him photos of her literary tour of the city.

The narrative shifts to Alfie at his desk in the closed bookshop. He rereads a letter from Hardings Bank, denying his latest business loan application. Despite the shop being busy, it is dying financially, and Alfie feels like he is running out of options. He apologizes to a photo of his father on his desk.

Tilly messages Alfie from Book Club bar in the East Village. She sends a selfie with her cocktail, and Alfie replies with a photo of himself reading in bed. Realizing it is late in London, she apologizes for disturbing him. Alfie says he enjoyed her virtual tour and ends his message with an x. Tilly sends an x back in reply.

On her way back to her hotel, Tilly makes a detour to see the Alphabet publishing office, where she was once offered a job. She runs into Liz Cohen, the publisher who offered her the position. Tilly explains that she turned down the job because her husband had become ill and subsequently passed away. Liz expresses her sympathy, and they part ways.

Three days later, Tilly arrives home in London to find Harper’s wedding invitation waiting for her. The wedding is set for November 30th, and the envelope includes a handwritten apology from Harper. After initially hiding the invitation, Tilly places it on her fridge.

Seeing the empty space on her shelf where Joe’s urn used to be spurs her to finally begin sorting through his belongings. Over the following weeks, she methodically clears out Joe’s things, turning his former desk into her own craft space.

One Sunday morning, Alfie teaches Tilly how to pitch a tent in the park. She is borrowing his camping gear for a trip to Scotland with Rachel, inspired by her September book from Joe. After they successfully pitch the tent, they crawl inside. In the small tent, she is acutely aware of Alfie’s proximity. As he describes the joys of camping, she notes he sounds like Joe. When Alfie moves to leave, Tilly stops him, telling him to relax for a minute. They sit together in comfortable silence, and Tilly thinks she might enjoy camping after all.

Tilly and Rachel arrive in Port Ellen, Islay, to hire bikes for their trip to Jura. Joe’s letter for September’s book, Stephen Neale’s Wild Camping (2015), expresses his regret at never convincing her to enjoy camping and encourages her to try wild camping. The bike shop owner warns them it is deer-stalking season on Jura.

They take a ferry to Jura and cycle across the wild landscape. While resting at the island’s only hotel, Tilly discovers Rachel has secretly started writing a novel. Tilly offers her enthusiastic support.

They cycle to a spot where they can see Barnhill, the house where George Orwell wrote his 1949 book 1984. They find a secluded bay to set up camp. Before pitching the tent, they spontaneously swim in the cold Atlantic. As they float in the water, a storm suddenly rolls in.

Tilly and Rachel scramble out of the sea as heavy rain and wind begin. They struggle to pitch the tent in the storm, chasing it down the beach when it blows away. They finally secure the tent and huddle inside, soaked and freezing. Unable to use their stove outdoors, they are forced to eat cold porridge.

The ordeal leads to a fight, with Rachel admitting that she hates camping. Tilly confronts Rachel about disappearing when Joe got sick. Rachel tearfully explains that her own father died of pancreatic cancer when she was 19, and she couldn’t bear to watch Tilly go through the same thing, though she recognizes it was wrong to abandon her friend. Tilly, understanding for the first time, comforts Rachel. They apologize to each other and fully reconcile.

Later, Tilly exchanges texts with Alfie about her challenging but beautiful camping experience. Alfie tells her Joe would be proud of her, and Tilly agrees she is proud of herself. Alfie deletes a message saying he is looking forward to seeing her and instead texts his mother to borrow her car.

Alfie waits for Tilly at the Stansted Airport arrivals gate, holding a sign. When Tilly appears, disheveled and exhausted, she launches herself at him in a fierce hug. Alfie gives her a Thermos of hot tea and a pair of clean, dry woolen socks. Overjoyed, Tilly puts them on immediately.

While Alfie drives her home, Tilly admits she misses Harper. Alfie reassures her that her sister is surely proud of her. He decides he wants to tell Tilly about his struggles with the bookshop but stops when he sees that she has fallen asleep, choosing not to burden her with his problems.

When they arrive outside her flat, Alfie offers to cook dinner while she showers. Tilly agrees. After her shower, she emerges to find Alfie cooking. She watches him for a moment, feeling a desire to get to know him better. She joins him in the kitchen, and they work side by side, filling the space with warmth.
