Plot Summary

Polly enters her 40th year surrounded by a close group of friends who have supported her through divorce, remarriage, and years of infertility. After receiving a DNA test as a birthday gift, she hesitates to share the results, even with her husband, Mark, and her brother, Garrison. When she finally reveals that the test shows unknown relatives, the information raises more questions than answers. Polly’s uncertainty deepens when she is contacted by one of the relatives, a teenage girl named Talia Burton, who is searching for family connections after her mother’s death. Their meeting is awkward and, at first, disappointing for Talia, but it begins an ongoing connection between them.

Polly continues to struggle with infertility, reflecting on years of failed treatments and emotional strain. Her relationship with Mark remains steady, though not unaffected by the pressure of trying to conceive. Polly works as a high school teacher at an all-girls private academy in Manhattan, where she finds purpose but also feels the passage of time acutely. Her father’s cognitive decline adds another layer of difficulty as he moves into a nursing facility and becomes increasingly unresponsive. Polly has a distant relationship with her mother, Mary, who is an acclaimed judge.

As Polly stays in contact with Talia, she is introduced to Talia’s father, Stephen Burton. During their meeting, Polly notices physical similarities between her and Stephen, which raises further suspicion about the DNA results. Stephen shares details about Talia’s mother’s difficult life, and Polly becomes more invested in understanding the connection. This leads her to consider visiting Talia’s grandmother, Barbara Burton, who runs an alpaca farm. Although some people in Polly’s life remain skeptical of the DNA test’s accuracy, Polly feels compelled to pursue the truth.

Meanwhile, Polly’s book club friendships, particularly with a woman named Sarah, continue to provide support. However, new challenges emerge when Polly learns that her fertility treatments have reached a point where she must consider options (surrogacy, etc.) that she is not ready to accept. On a visit to Barbara’s farm, Barbara suggests that Sarah should see a doctor. Although Polly initially dismisses this suggestion, she later discovers that Sarah, who had cancer, now faces a terminal prognosis. This news rearranges Polly’s life, as she begins to prepare for the loss of one of her closest friends while also coming to terms with the possibility that she might never become pregnant.

Over the following months, Polly supports Sarah and helps Mark’s family after a storm damages their home. Mark’s parents, Lou and Skipper, move into Sarah’s cottage while their home is repaired, and Sarah eventually comes to live with them during her final months. Polly reconnects with one of her students, Josephine, who is struggling with the expectations placed on her as a Harvard college student. Polly encourages Josephine to pursue a path that brings her fulfillment rather than meeting others’ expectations. Through these interactions, Polly reflects on her own life choices and the pressures she has faced.

As Sarah’s condition worsens, Polly spends more time with her and begins to understand the depth of Sarah’s experiences, including her own inability to have children. Eventually, Sarah dies peacefully, leaving behind plans for her remains and a final gift for Polly: her cottage, along with the means to maintain it.

Polly’s search for answers about her biological identity reaches a turning point. She visits Barbara’s farm again, where she meets Barbara’s partner, Andre Bettman. Polly immediately senses a connection and realizes that Andre is her biological father. Andre confirms that Stephen is her half-brother but expresses no desire to have a relationship with Polly. Polly confronts her mother about the truth. During their conversation, Mary admits to having had an affair with Andre and explains the circumstances that led to it. She was uncertain about Polly’s paternity and chose not to disclose the truth. The conversation becomes tense, with both women expressing long-held frustrations about their relationship. Rather than bringing closure, the revelation complicates Polly’s understanding of her family and her own identity.

In the aftermath, Polly processes the loss of Sarah, the truth about her parentage, and the ongoing decline of her father, who is now barely communicative. The book club disbands following Sarah’s death, though Polly remains connected to her friends in new ways. She invites them to the cottage and shares Sarah’s belongings, allowing them to honor her memory together. After stepping away from fertility treatments, Polly becomes pregnant. She shares the news with those who have supported her most closely and begins to consider how and when to tell her mother. The pregnancy introduces a new chapter in her life, even as many aspects of her past remain unresolved.
