The Light of Luna Park

In June 1926, Althea Anderson is a nursing student at Bellevue Hospital in New York City who watches helplessly as a premature infant named Cybil dies. Althea carries a newspaper clipping about Dr. Martin Couney, a physician who treats premature babies free of charge in incubator wards at Luna Park on Coney Island. When she suggests this option to the attending physician, Dr. Bricknell, he dismisses Couney as a quack and forbids her from telling the parents. Althea obeys, and Cybil dies. The guilt is compounded by a lifelong burden: Althea's own mother died giving birth to her, and she has devoted herself to nursing to repay that debt.

Twenty-four years later, in December 1950, Stella Wright is a special education teacher in Poughkeepsie, New York, grieving the death of her mother, Althea, three months earlier. Her husband, Jack, a World War II veteran who experiences combat-related flashbacks but refuses to discuss his wartime experiences, tries to comfort her, but tensions simmer over his secrecy and his desire to start a family. Stella teaches children with disabilities in a windowless basement under the hostile supervision of Principal Gardner. On the last day before Christmas break, she discovers that the supplies Gardner promised are child-sized straitjackets. She has the children paint over them and quits.

In July 1926, when another premature baby, Margaret Perkins, is born at Bellevue, Althea tells the parents, Hattie and Michael Perkins, about Dr. Couney's incubators. Michael refuses, calling the facility a sideshow, and silences Hattie. Althea smuggles the baby out of the hospital and takes her to Luna Park, where head nurse Louise Recht places her in an incubator. Althea writes her own address on the intake form and tells the parents their daughter has died. A fellow nurse, Ida Berry, unknowingly files a death certificate for Margaret, deepening the legal danger of Althea's deception. Over the following weeks, Althea visits Margaret daily, and when the baby develops pneumonia, Althea secures life-saving antiserum from a nearby hospital.

During the Christmas of 1950, Jack raises the topic of children, but Stella resists. In January 1951, she travels to New York City to clean out Althea's apartment. There she discovers a charm box containing two puzzling items: a letter addressed to "Nurse Anderson" from Hattie Perkins, who grieves for a daughter named Margaret who died at birth at Bellevue, and a thumbprint card, a keepsake stamped with the baby's print, proving Margaret survived at least a month. Stella is baffled, as her mother was a homemaker, not a nurse, and resolves to investigate.

In September 1926, Althea takes the now five-pound Margaret from Luna Park, intending to return her to her parents. Before she can, Hattie appears in Bellevue's emergency room with a broken nose inflicted by Michael. Althea writes Hattie a letter asking to meet, promising news about Margaret. That night, Miss Caswell, the supervising administrator of the Nurses' Residence, discovers the baby hidden in Althea's room. Caught, Althea claims the baby is hers and names her Stella on the spot, inspired by the baby's bright eyes. Expelled from nursing school, Althea secures a live-in caretaker position with Mrs. Wallace, an elderly widow, posing as a widow.

When Mrs. Wallace fractures her collarbone, Althea calls in Dr. Charles Morrison, a young physician impressed by her medical knowledge. A connection develops between them. A reply to Althea's letter arrives not from Hattie but from Michael, who forbids further contact. Althea goes to the Perkinses' home to return Stella but watches through the window as Michael violently attacks Hattie. Unable to subject Stella to a dangerous home, Althea walks away with the baby, committing to raising her permanently.

Stella's investigation takes her to Bellevue and the Bureau of Vital Statistics. She discovers Margaret Perkins's death certificate, signed by Ida Berry, and Margaret's birth certificate in Althea's unmistakable handwriting. Stella's own birth certificate is missing, and her parents' marriage certificate reveals they wed in July 1927, nearly a year after Stella's supposed September 1926 birth. When Stella calls Ann Leslie, her mother's closest friend, Ann insists Althea was terrified of blood, a claim Stella knows to be false.

In Althea's timeline, Charlie invites her to present her knowledge of incubators to physicians from the American Medical Association (AMA). Charlie falls in love with her, and they share their first kiss. He announces a partnership with pioneering neonatologist Dr. Julius Hess to bring incubator technology into mainstream hospitals, work that will connect him to Dr. Couney and Bellevue. When Charlie proposes, Althea refuses, knowing that proximity to those circles would expose her deception. She places a matrimonial advertisement to find a husband who can provide stability for Stella.

Stella travels to the Couneys' home on Coney Island, where Nurse Louise Recht and Hildegarde Couney, Dr. Couney's daughter, confirm that a nurse named Althea brought a baby to Luna Park in 1926 and took the baby home in September. Louise confirms Althea was not pregnant at the time. Stella recognizes the pink bows on incubator babies in old photographs as identical to one in her mother's charm box. A terrifying possibility takes shape: She is Margaret Perkins, and Althea raised her without Hattie's knowledge.

Standing in the ruins of Luna Park, Stella breaks down and calls Jack, telling him everything. He travels to the city to be with her. Together, they discover matrimonial ads lining the charm box's bottom, including one matching Althea's circumstances: a young widow with an infant seeking a kind man. Stella realizes her mother met her father, Horace Johnson, through a newspaper ad, choosing stability for Stella over the love she had with Charlie.

Stella visits Hattie's home and finds her beaten nearly to death by Michael. She calls an ambulance, identifying herself as Hattie's daughter and noticing their identical features. At Bellevue, Hattie confirms she and Michael refused to take Margaret to Coney Island but insists her daughter is dead. When Michael arrives, Hattie dismisses Stella as a hospital worker to protect her. Stella then visits the hospital's incubator ward, where the doctor recognizes her as Althea's daughter and introduces himself as Dr. Charles Morrison.

Back in Poughkeepsie, Stella receives two letters. Dr. Morrison's includes her baptism certificate, listing her birthdate as July 5, 1926, and confirms that Althea never bore a child. He explains that Althea left him because his work would have exposed her secret. Hattie writes a brief note with a P.O. box address, telling Stella she wanted Stella to be proud of her, a small step toward independence from Michael.

The novel closes with a chapter set in July 1946. Althea, now widowed after Horace's death, visits Charlie for the first time in twenty years. She shows him photographs of the twenty-year-old Stella. They spend the night together, rekindling their love. The next morning, Althea leaves again without explanation, choosing Stella's safety over her own happiness one final time. She tells Charlie only that she loves him.

In the present, Stella returns to her students armed with new knowledge of special education and legal leverage against Principal Gardner, securing full days and proper conditions for her class. She and Jack discuss having children, and Stella is finally open to the idea, envisioning a future where she can be both a mother and a teacher.
