Summary
This chapter is Wen's long confession to Nick, delivered in the present day from San Francisco. It traces the arc of her adult life from the moment she and Charles accept donor funding to the present, revealing the full extent of the choices she made—and the consequences that followed.
After signing the contract with the institute's donors, Wen and Charles move into a furnished two-story home with a weathervane and green shutters—the same house Wen had admired. The home has a washer and dryer, climate control, a grandfather clock, and a lockable office door. Wen undergoes dental repair (her broken teeth are reshaped and a false tooth added), and both she and Charles receive medical examinations, vaccinations, and submit genetic samples to the institute's genomic database. Wen swears she will not grow comfortable, knowing everything can be taken away, but she cannot help feeling hope.
Officially, the lab belongs to Charles. Wen works alongside him, but she deliberately avoids aligning with the other foreign scientists, who eat together and share housing. Instead, she speaks only English and seeks out Otto, a fellow left-handed scientist. Their conversations remind Wen of her talks with Ping, except Otto is not doubtful—he shares her conviction that DNA will one day be readable and even editable. Wen reflects on the word fortune, noting that it means both luck and money, and that the two meanings seem entwined. She remembers Lanlan, whose family's wealth became her punishment.
Charles wants a family; Wen does not. She has known since girlhood, watching her mother's time belong to everyone but herself. Charles argues that motherhood is biological and that a family will make them a real American family. They argue often.
When Mao Zedong dies, Charles brings Wen the newspaper. She reflects on the mass graves of the famines and wonders whether the mourners feel relief. That evening, they go to an Italian restaurant for the first time—a celebratory meal with wine. Wen gets drunk, and that night, in a rare moment of desire, she forgets to place her diaphragm.
Wen becomes pregnant. She considers an abortion and plans to keep it secret from Charles, but Otto calls to congratulate them—Charles has already told him. Wen meets Otto's wife, Naomi, and their five children, including baby Thomas. Naomi is kind but clearly unhappy. Otto tells Wen she will love her daughter and that children give the work meaning.
Lily is born. Wen's memory of the birth is fragmented—she remembers blood, transfusions, and listing tasks in case she died. Charles names the baby Lily. Wen's fear evaporates when she holds her daughter; she feels a love she describes as a conviction that Lily must live and stay close to her. Lily becomes the glue holding the family together. Charles is the easier parent to adore, and they adore each other.
Wen has her tubes tied without telling Charles. She loves Lily but does not want another child. In her late-night lab work, she discovers imprinting factors—one that suppresses paternal gene expression and one that suppresses maternal genes. She keeps this discovery secret, telling no one, not even Charles.
In spring 1981, Naomi dies by suicide—an overdose of Seconal. Otto is angry, not sad. He worries that his children might inherit Naomi's sadness, noting that her mother also took her own life. Thomas, only half a year older than Lily, already seems like a perpetually disappointed child.
The lab is shut down. The board is displeased with the lack of progress. Charles and Wen move to Florida to research fruit and vegetable genomics. Wen has been isolating enhanced mutants of her imprinting factors, working toward an epigenome editor. She shares her secret with Otto. The therapy uses a modified simian polio virus to deliver the imprinting factors, suppressing one parent's genetic contribution throughout the body. Otto and Wen secretly treat both Thomas and Lily—deprioritizing Naomi's genes in Thomas and Charles's genes in Lily. They observe the children becoming left-handed as a sign of success.
Thomas dies by suicide at nineteen. Wen falls into a deep depression. Lily grows up to be, in Wen's words, practically a stranger.
Wen does not learn of Lily's relationship with Matthew—Otto's son—until their wedding weekend. Matthew had been using a different last name. Otto and Wen speak for the first time since Thomas's death, agreeing the relationship cannot last. It does. When Lily struggles to conceive, they realize the therapy damaged the X chromosome Lily inherited from Charles, affecting her reproductive system.
IVF offers the possibility of germline editing. Otto proposes emphasizing Lily's genes, but they cannot be certain of her genome's integrity after the earlier therapy. Instead, they create Nick with primarily his father's genetic contribution, editing regions related to inherited depression. This time, the therapy works far better than they imagined.
Lily leaves with Nick, feeling betrayed, and swears never to speak to Wen again. Wen returns to Tampa and tends to Charles until he dies. She then tracks Nick to Arizona, then Washington, and finally San Francisco. She has been trying to compose an apology. She asks Nick to bring Lily to see her—not for forgiveness, which she knows is impossible, but to say she is sorry.

Character Development
Wen emerges in this chapter as a figure of profound contradiction. She is a scientist who wants to control inheritance and a mother who secretly alters her own daughter's genome. She is capable of deep love for Lily yet makes choices that ultimately alienate her. Her reflections on fortune, time, and choice reveal a woman shaped by scarcity—of resources, of autonomy, of time—who tries to compensate through science. Her confession to Nick is framed by guilt and a desire for acknowledgment rather than forgiveness.
Charles remains largely opaque, seen through Wen's dismissive lens. He wants a family for legitimacy, names Lily, and is a more effusive parent. He never learns of Wen's secret work or her tubal ligation.
Otto is Wen's intellectual and emotional counterpart. His grief over Naomi and his fear for his children make him complicit in the secret therapy. His loss of Thomas is the chapter's most devastating consequence of their experiment.
Lily is mostly observed from outside—as a baby, a gifted child, a stranger to her mother, and finally a betrayed adult who cuts Wen off.
Nick is the silent recipient of Wen's confession. The chapter is addressed to him, and his existence is the culmination of Wen's choices.
Themes, Symbols, or Motifs
Genetic engineering and scientific ethics. The chapter dramatizes the gap between scientific possibility and moral consequence. Wen's imprinting factors are a genuine discovery, but their application to children without consent is indefensible—a point Wen herself concedes.
Motherhood and reproductive autonomy. Wen's refusal to be a mother, her secret tubal ligation, and her forgotten diaphragm all speak to her struggle for control over her own body. Yet she also uses science to control her daughter's body, creating a painful irony.
Fate versus choice. Wen's central question—what if we could choose?—drives the entire chapter. She wants to guide inheritance, to make it less about the luck of the draw. The results are catastrophic.
Fortune and luck. Wen's meditation on the word fortune—chance and money—connects her Chinese past (Lanlan's family) to her American present (donor funding). The four-leaf clovers she grows in Florida are a symbol of her desperate hope for luck to change.
Secrets and deception. Wen keeps her discovery, her tubal ligation, and the therapy secret from Charles. She and Otto keep the therapy secret from their children. The chapter is structured as a confession—the final unburdening of these secrets.
Control over time. Wen's ability to stretch time, first granted by the seed, recurs here. She resents the clock's movement when engrossed in work, then realizes she can keep time still. This motif connects her supernatural gift to her scientific ambition.
Inheritance and heritability. The chapter is obsessed with what is passed down—genes, sadness, luck, trauma. Otto's fear about Naomi's depression and Wen's desire to give Lily a better life both hinge on inheritance.
Why This Chapter Matters
This is the novel's central revelation. Everything Wen has hinted at throughout the narrative—her past in China, her marriage, her scientific work, her relationship with Lily—converges here in a single confession. The chapter explains Nick's existence, his genetic makeup, and the estrangement between Wen and Lily. It also completes the moral arc of the novel: Wen's desire to improve her daughter's life through science leads to the very outcomes she feared—Thomas's death, Lily's infertility, and the loss of her family. The chapter reframes the entire novel as a cautionary tale about the limits of control and the unintended consequences of love expressed through manipulation.
Study Questions and Answers
1. Why does Wen decide to secretly treat Lily and Thomas with the gene therapy, and what does this reveal about her motivations?
Wen treats Lily to give her a second chance at the life Wen herself never had—an American life, unburdened by the disadvantages Wen faced as a Chinese woman. She wants Lily to accomplish more than she did. With Thomas, she wants to spare him from inheriting Naomi's depression. Both motivations are rooted in love, but they are expressed through control rather than trust. Wen never asks Lily or Thomas what they want; she assumes she knows what is best. This reveals a fundamental flaw in her character: her belief that she can and should engineer outcomes for the people she loves.
2. How does the chapter use the concept of fortune to connect Wen's past and present?
Wen reflects that fortune means both luck and money, and that the two meanings are entwined—you never describe someone as fortunate who is penniless. This connects her Chinese past, where Lanlan's family wealth became a punishment, to her American present, where donor money funds her home, her lab, and ultimately her experiments. The word also carries irony: Wen's fortune (money) leads her to believe she can control luck (genetic inheritance), but the results—Thomas's death, Lily's estrangement—show that fortune cannot be engineered. Her four-leaf clovers in Florida are a symbol of this futile attempt to cultivate luck.
3. What does Wen's confession to Nick reveal about her understanding of her own guilt?
Wen acknowledges that what she did was indefensible, selfish, foolish, and dangerous. She does not seek forgiveness, saying she understands it is unforgivable. Yet her confession is also an attempt to be understood—she explains that she loved Lily differently than Lily wanted to be loved. This tension between self-awareness and self-justification is central to the chapter. Wen knows she was wrong, but she still wants Nick to ask Lily to come see her. Her guilt is real, but so is her desire for connection. The confession is not an apology that expects absolution; it is an accounting of a life shaped by choices she now regrets.
