Hello, Sunshine

On her 35th birthday, Sunshine Mackenzie, a famous YouTube cooking star with 2.7 million Twitter followers, wakes in her Tribeca loft beside her husband of 14 years, Danny Walker, an architect. Her favorite Rolling Stones song, "Moonlight Mile," plays on the radio. Then an anonymous email arrives from someone calling themselves Aintnosunshine, threatening to ruin her. A tweet appears on her verified account declaring, "I'm a fraud." Sunshine admits to the reader that the hacker is telling the truth.

The hack escalates. A tweet displays Sunshine's signature tomato pie recipe with her name crossed out and replaced by "Meredith Landy," the wife of her executive producer, Ryan Landy. Meredith, a former sous-chef, created the recipe. Ryan arrives radiating confidence, having secured Meredith's public denial, and insists they use Sunshine's surprise birthday party that night to control the narrative. Sunshine privately acknowledges what no one says aloud: Meredith is the real chef, and the deception runs deep.

Through flashback, the novel reveals Sunshine's origin. On her 26th birthday, she was tending bar at a run-down grill in Red Hook, Brooklyn, while she and Danny were broke. Ryan walked in that night, having just been fired from the Food Network. He saw Sunshine's "optics": young, relatable, the "right amount of pretty." He proposed building a persona: Sunshine Mackenzie, a farmer's daughter from the South. What started as one recipe and one video became bestselling cookbooks and an empire built on fabrication.

Danny has planned the birthday party at Locanda Verde, a Tribeca restaurant, for 50 friends. During the event, the hacker posts compromising photographs of Sunshine and Ryan, then a naked photograph of Sunshine with Ryan visible as the photographer. Meredith storms out. Danny calmly tells the guests he took the photo himself, but once outside, his composure breaks. Sunshine admits the night with Ryan was "just one night." Danny whispers, "You should have said nothing at all," and leaves.

Sunshine walks to Battery Park. The night with Ryan occurred at the St. Regis in Aspen during a food industry event. She told him it was a mistake and chose not to confess to Danny. Meanwhile, the hacker posts her yearbook photo, her real name (Sunshine Stephens), and her actual background: raised in Montauk on Long Island, daughter of a famed composer, not a farmer's daughter. In a rage, Sunshine hurls her phone into the Hudson River.

Back at the loft, Ryan confesses his love and proposes they leave their spouses. Sunshine refuses, and he walks out, ending their partnership. The next morning, her career collapses. All advertisers pull out. Ryan and Meredith announce their own show, positioning Sunshine as the villain. Her publisher cancels her cookbook contract. Her assistant, Violet, quits to work for Ryan. Sunshine visits Danny at a construction site, but he tells her the problem was never one lie but how the small lies paved the way for important ones. "I just don't know you," he says, and walks away. Their lawyer informs Sunshine that Danny has filed for legal separation, returned the publisher's advance, and sold the apartment.

With nowhere else to go, Sunshine drives to Montauk. Her childhood home has been sold to a celebrity couple. Her older sister, Rain Stephens, and Rain's six-year-old daughter, Sammy, live in the small guesthouse behind the main house. Rain greets Sunshine with contempt; they have barely spoken in five years. Their father, Steve Stephens, was a celebrated film composer who developed rigid superstitious rules after his second wife left. Rain devoted herself to maintaining his world, turning down a Princeton scholarship to stay home, while Sunshine fled to the University of Oregon. Rain blames Sunshine for abandoning her; Sunshine resents Rain for choosing their father over her own life.

Rain's boyfriend, Thomas, a commercial fisherman, has been hospitalized, leaving her without childcare. She reluctantly allows Sunshine to watch Sammy overnight. Sunshine bonds with her precocious niece, who reads constantly and has almost no friends her age.

Sunshine devises a plan to rehabilitate her career by working at 28, an acclaimed local restaurant run by Chef Z, a reclusive Le Cordon Bleu-trained chef. Using a fake name, she gets a trial shift and is assigned to "trash": monitoring what diners leave on their plates so Z can adjust his menus. She also meets Ethan Nash, Thomas's fishing partner, who teaches at Yale and supplies fish to top restaurants. Blunt and unimpressed by Sunshine's fame, Ethan challenges her to stop pretending and becomes her closest confidant in Montauk.

The hacker redirects Sunshine's YouTube channel to rival cooking star Amber Rucci's page, revealing that Amber has taken the Food Network show and the cookbook deal that were once Sunshine's. At Sammy's camp, Sunshine feels unexpected pride when Sammy wins the top award for designing a self-sustaining irrigation system. A counselor nominates Sammy for a gifted program in New York.

Sunshine discovers she is pregnant with Danny's baby. She carries the news for a week. When she calls Danny, his longtime friend and collaborator, Maggie, answers while Danny is in the shower. Sunshine hangs up, assuming he has moved on. She then spots Amber dining at 28 and, overcome with rage, dumps a plate of rejected peaches into Amber's lap.

Tensions with Rain escalate when Sunshine takes Sammy fishing without permission. The argument peaks when Sunshine accuses Rain of being like their father. Rain kicks her out. At Amber's cookbook release party in East Hampton, Sunshine confronts Amber about the hack, but Amber denies involvement. The truth hits Sunshine: Danny was the hacker. He was standing over the bed when the first tweet arrived. He sold the apartment. He forced her back to Montauk.

Sunshine confronts Danny in the Tribeca apartment, which he has kept and refurnished. He confirms everything, explaining that Maggie was only redesigning the apartment. Danny says Sunshine was "so far gone" that there was no other way to reach her; the Food Network show would have grown her audience from millions to tens of millions. He recalls the football game where they met, how she refused to give him a friend's extra beer because she wanted it. That lack of pretense was what he fell in love with, and what she had lost. Sunshine removes her wedding ring and leaves.

Over the following weeks, Sunshine works at 28 and walks through her renovated childhood home. Sitting in her old bedroom, still painted the same purple, she remembers Rain refusing to leave for Princeton: "I wouldn't leave you." Sunshine realizes that running is the surest way to end up where you started.

Agent Julie Diaz proposes a new show called "Cooking from Scratch," in which Sunshine would start over honestly. Meanwhile, Sunshine reconciles with Rain. Using Ethan's key to their old home, Sunshine makes her grilled cheese sandwich, the one real dish she knows, and plays "Moonlight Mile." Rain tells her about Isabella Beeton, the Victorian-era cookbook author who plagiarized her recipes but innovated by putting the ingredient list at the beginning, now standard practice. Rain's point: Sunshine can still build something meaningful from her mistakes. Sunshine apologizes for comparing Rain to their father, admitting she herself uses lies the way he used rules. Rain accepts and invites her home.

Sunshine calls Julie to accept the show but finds she cannot say yes. She turns it down, choosing not to return to the public eye until she knows what she is putting out there. Chef Z connects her with a job running a specialty food store in Tribeca. Rain agrees to consider letting Sammy attend a weekend gifted program, with Sunshine nearby in Harlem.

Danny arrives at the guesthouse. Rain calls what he did "shitty" but admits she wishes she had thought of it first, then leaves them alone. Danny tells Sunshine he took down the website and cannot stop thinking about her. She tells him she is pregnant. After a pause, he holds her. Neither knows if they can repair their marriage, but neither is ready to let go.

On her last morning, Sunshine leaves her car in Montauk so Sammy will know she is coming back and takes the train to New York. A young woman recognizes her and asks for a selfie. Sunshine obliges, covering her belly and making a peace sign. The girl posts the photo without a word. Sunshine reflects that some people will remember who she is, some will not, and the rest will not care, and considers this a fitting way to say goodbye.
