⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.
Summary
Chapter 38 opens with sixteen-year-old Wren hiding breathless inside her bedroom closet, sealed behind a reinforced metal door that she and her mother installed two years earlier on a Super Bowl Sunday. The precaution was part of a plan they devised together for the day Angela might become violent and lose control of her impulses. Wren has locked her bedroom door and barricaded it with her desk and chair, and she has stocked the closet with enough water and nonperishable food to last several days.
The danger is real now. Angela paces the hallway in a venomous, hungry state. Wren reflects that during her last visit with Genevieve, the family's social worker, she deliberately concealed how rapidly her mother had declined in recent months. Wren does not want to be placed in a foster home—she has learned to take care of herself—and she does not want her mother sent to a facility, because she takes care of Angela too.
The chapter recalls the good days they still share: evenings on the roof watching sunsets or celestial events, mornings when Angela makes pancakes with fresh blackberries, afternoons of reading, television, and long conversations that drift into naps. But this is not one of those days.
Angela breaks through Wren's bedroom door, rattling the entire house. She tries to topple the reinforced closet door but cannot, thanks to their planning. The failure seems to make Angela more determined and more furious. Her claws screech against the metal door, and she slides her tongue through the gap at the bottom, trying to reach Wren, who presses herself against the far wall behind a rack of shirts.
Eventually Angela loses interest and moves to another room. Wren remains hidden, terrified, until she decides the risk of escape is worth taking. She plots her route, bolts through the house, grabs the car keys and her bag, sprints to the car, and drives away—going farther than necessary, speeding through a thirty-five-mile-per-hour zone at sixty until she reaches the high school.
The football stadium is lit up for one of the final games of the season. The announcer calls a touchdown, the home crowd cheers, and the marching band plays. Parked in front of the auditorium, Wren dials Dr. Park's twenty-four-hour line on her flip phone. Her voice quivers as she asks to speak with Dr. Park about her mother, Angela Wyatt. She identifies herself as Wren Wyatt and says she is authorized to call on her mother's behalf. She reports an emergency: Angela needs a higher dose of her medication, though Wren is not sure which one. She confirms the number and asks Dr. Park to call back soon, closing with the admission that her mother has not been well.

Character Development
Wren emerges in this chapter as a young person forced into an adult role far beyond her years. She has internalized the caregiver identity completely: she hides her mother's decline from the social worker to avoid foster care, and she resists the idea of a facility because she believes she can manage on her own. Her planning is meticulous—the reinforced door, the barricade, the stockpiled food—yet the chapter shows that no amount of preparation can erase the terror of the moment. Her voice quivers on the phone, a reminder that her composure is fragile.
Angela's transformation is starkly visible here. The woman who makes blackberry pancakes and watches sunsets with her daughter is now described in animalistic terms: venomous, hungry, clawing, using her tongue to probe for her child. The chapter does not show Angela's interiority; she is seen entirely through Wren's frightened perspective, which makes her seem less like a person and more like a threat.
Themes, Symbols, or Motifs
Caregiver burden and self-reliance. Wren's refusal to involve Genevieve or consider a facility reflects the isolation that often accompanies caregiving. She has made herself both protector and provider, and the cost is visible in her fear and her trembling voice.
Normalcy vs. crisis. The chapter juxtaposes the good days—roof sunsets, pancakes, lazy afternoons—against the violent episode unfolding in the present. The contrast underscores how unpredictable Angela's condition has become and how much Wren clings to the memory of normalcy.
Animalistic transformation. Angela's claws, tongue, and predatory pacing suggest a body no longer fully human. The reinforced door, installed as a precaution, becomes a literal barrier between the human world Wren occupies and the animal state her mother has entered.
Protective planning as love. The door was installed with Angela's own words—in case you need protection—which reframes the precaution as an act of maternal care even as the mother herself becomes the threat. The plan they built together is what saves Wren.
Why This Chapter Matters
This chapter dramatizes the consequences of Angela's decline in concrete, physical terms. The reader sees the danger Wren has been managing quietly for months, and the scene at the high school—Wren alone in a parking lot while a football game plays on—underscores her isolation. Her call to Dr. Park is a rare moment of reaching out for help, and it signals that even Wren's self-sufficiency has limits. The chapter also sets up the medical intervention that may drive the next phase of the story.
Study Questions
1. Why does Wren hide the severity of Angela's decline from Genevieve, and what does this reveal about her priorities?
Wren hides the decline because she fears two outcomes: being placed in foster care and having her mother sent to a facility. She believes she can take care of herself and her mother, and she values their remaining good days too much to risk losing them. This reveals that Wren prioritizes staying with her mother over her own safety and well-being, even when the danger is immediate.
2. How does the chapter use the contrast between the good days and the violent episode to shape the reader's understanding of Angela's condition?
The good days—roof sunsets, blackberry pancakes, long conversations—show that Angela is not always a threat and that Wren's love for her is grounded in real, shared experiences. The violent episode shows how quickly and completely the condition can overtake her. The contrast makes the decline feel more tragic and explains why Wren is so reluctant to give up on caring for her mother.
3. What does Wren's decision to call Dr. Park from the high school parking lot suggest about her state of mind?
Wren drives farther than necessary and parks at the school during a football game, a place associated with normal teenage life. The setting highlights how far she is from that normalcy. Her call is a carefully controlled plea for help—she identifies herself as authorized, states the emergency, and asks for a callback—but her trembling voice betrays her fear. The call suggests Wren is reaching the limit of what she can handle alone, even as she continues to manage the situation on her own terms.
