Chapter 21: Summary and Analysis
⚠️ 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 21 is Mallory's confession. She tells Adrian the full story of how her life unraveled, beginning with a sacral stress fracture in September of her senior year of high school. The injury sidelined her from cross-country at the start of the season, and doctors prescribed OxyContin for the pain—a prescription that would eventually derail everything.
Mallory describes her family situation: a single mother who worked as a billing administrator at Mercy Hospital, smoked a pack a day, and constantly reminded her daughters that they had no extended family to lean on. The refrain of her childhood was showing up for each other.
On Saturday, October 7, Mallory's mother was called into mandatory overtime and insisted Mallory drive Beth and her friend Chenguang to Storybook Land, a kiddie park the two teenagers were visiting ironically. Mallory wanted to skip the trip to attend her cross-country meet, but her mother overruled her.
The trip was delayed by a stop at Walgreens for Benadryl (Chenguang had a spider bite), pushing them onto the Atlantic City Expressway later than planned. While driving at highway speed, Mallory received a stream of texts from her friend Lacey about race results. She glanced down at her phone to reply. In her rearview mirror she saw Beth and Chenguang sharing a strand of gummy candy. Then she woke up in a hospital in Vineland, New Jersey, on Wednesday.
A mountain bike had come loose from an SUV ahead, causing a multi-car accident. Mallory suffered a broken leg and cracked ribs. Chenguang walked away without a scratch. Beth was the only fatality. Mallory's phone was lost in the crash, and she never learned who placed third in the race.
After two weeks in the hospital, Mallory left with a new OxyContin prescription. By February, doctors cut her off, and she discovered the drug had rewired her brain. She began scrounging pills from classmates' homes, then buying from dealers, then transitioning to heroin. She finished high school barely, lost her Penn State offer, and spent nights in Northern Liberties crashing on the sofa of a 38-year-old man named Isaac.
Her mother tried to help but couldn't compete with the addiction. The mother suffered a heart attack on a bus and nearly died; Mallory didn't learn about it until six months later, when she called from rehab. Her mother hung up, then had a friend named Tony tell Mallory she didn't want to hear from her. The number was disconnected. Mallory hasn't spoken to her mother in two years.
Now, confessing to Adrian, Mallory admits she lied about the drawings—she has no memory of drawing them, but assumes she must have, since it's the only logical explanation. She tells him she's leaving Spring Brook on Monday to live with her sponsor Russell.
Adrian's response is unexpected. He reveals that when he returned home the night before, he found a new pencil drawing on his desk. He reasons that Mallory couldn't have sneaked into his house, and neither could Teddy. The most likely explanation, he says, is that Anya is drawing the pictures—and she wants him to know Mallory is telling the truth.

Character Development
Mallory — This chapter transforms Mallory from an unreliable narrator into a deeply sympathetic one. Her confession reveals the guilt she's carried for years: she believes the crash was her fault because she was texting, even though everyone else blames the driver with the mountain bike. Her addiction is presented not as a moral failing but as a medical consequence of a prescription she was given as a teenager. Her decision to confess to Adrian, even knowing it might cost her his trust, shows growth.
Adrian — Adrian's response to Mallory's confession is measured. He doesn't offer easy forgiveness, but he also doesn't reject her. His revelation about the drawing on his desk shows he's willing to consider the supernatural explanation he previously dismissed.
Mallory's mother — Though absent from the present-day scenes, the mother's story is told through Mallory's memories. She's a hardworking single parent who tried to help her daughter but was ultimately pushed away by the addiction. Her decision to cut off contact is presented as heartbreaking but understandable.
Themes, Symbols, or Motifs
Survivor's guilt — Mallory's entire narrative is shaped by her belief that she caused her sister's death. Even though the accident was caused by the mountain bike, she can't forgive herself for looking at her phone.
Addiction as a consequence, not a choice — The chapter carefully traces how a legitimate medical prescription led to addiction, emphasizing that no one warned Mallory about the risks.
Family obligation — The refrain showing up for each other recurs throughout Mallory's story, and her failure to show up for Beth (in her own mind) is the wound that defines her.
Confession and trust — Mallory's confession to Adrian is the emotional core of the chapter. She's sharing a story she's never told anyone outside of NA meetings.
The supernatural drawings — Adrian's discovery of the new drawing reframes the mystery. If Mallory didn't draw it, and Teddy didn't, then Anya's presence becomes harder to deny.
Why This Chapter Matters
This chapter is the emotional and narrative turning point of the novel. It provides the backstory that explains Mallory's behavior throughout the book—her secrecy, her anxiety, her need to be believed. It also shifts the supernatural mystery into a new phase: Adrian's discovery of the drawing on his desk is the first piece of evidence that comes from outside Mallory's own experience, suggesting the drawings are real and Anya is responsible.
Study Questions and Answers
1. How does Mallory's account of the accident complicate the question of blame?
Mallory believes the crash was her fault because she was texting while driving, even though the accident was caused by a mountain bike falling from an SUV ahead. The chapter deliberately leaves this unresolved: Adrian points out that she might not have been able to avoid the bike even if she'd been paying attention, but Mallory insists she could have. The question of whether she's right is left to the reader.
2. What role does the showing up for each other refrain play in Mallory's guilt?
The refrain was a constant reminder from her mother that the family had no one else to rely on. Mallory's guilt is compounded by the fact that she was supposed to be showing up for Beth on the day of the accident—she was driving her sister, and she feels she failed. The refrain makes her failure feel more personal and more damning.
3. How does Adrian's discovery of the drawing change the reader's understanding of the supernatural mystery?
Until this point, the drawings could be explained as Mallory's own doing—perhaps she was drawing them in her sleep or in a dissociative state. Adrian's discovery of a drawing on his own desk, in his own home, eliminates Mallory as the artist. It's the first evidence that the drawings are happening independently of Mallory, and it suggests Anya is actively trying to communicate with Adrian as well.
