Summary

Ella is in a car driven by her social worker Amara, heading to New Hampshire to meet her biological father for the first time. She reflects on her friend Anton, now in juvenile detention, and the hoarded, abusive home she fled. When they arrive at a tidy apartment building, Amara reassures her. The father, a man in his forties, opens the door and immediately appears familiar because of their strong resemblance. He explains that he tried to have a relationship with Ella but her mother blocked him while he was on parole. Ella decides to stay. He introduces an “infinity promise” and vows to always take care of her.

Years later, as a teenager, Ella tells him the full truth about her mother’s abuse and her final act of arson. Instead of horror, he responds with approval, saying the victim deserved it. He then admits that he went to prison for assaulting a man who was having an affair with his girlfriend—Ella’s mother. He tells Ella that when people deserve punishment, it is sometimes up to you to deliver it.

Themes, Symbols, or Motifs

Order vs. Chaos: The father’s spotless apartment contrasts with the hoarded, decaying house where Ella grew up, symbolizing safety and a new beginning.
Infinity Promise: Represents an unbreakable bond and a moral code that overrides legal or conventional ethics.
Justice as Personal Vengeance: Both father and Ella believe that some acts of violence are justified when the system fails. The father’s approval of the arson reinforces this theme.
Resemblance: The physical similarity between Ella and her father underscores their deeper connection and foreshadows their shared capacity for extreme action.

Why This Chapter Matters

This chapter provides the emotional resolution of Ella’s journey. It reveals that her father is not only a safe haven but also someone who shares her ruthless sense of justice. It recasts the earlier violence of the book, showing that Ella’s actions were shaped by her upbringing and her father’s influence. The chapter also hints at the larger moral ambiguity of the story: who is truly guilty, and who decides guilt?

Study Questions & Answers

What makes Ella decide to stay with her father rather than return to the group home?
Answer: She is struck by the cleanliness and order of his apartment, the opposite of her mother’s hoarded home. She sees in his face a reflection of herself and feels a sense of belonging. His nervous, excited way of speaking reminds her of her own mannerisms, making him feel less like a stranger.
What does the “infinity promise” signify in the context of their relationship?
Answer: It is a vow that cannot be broken. He uses it to assure Ella that he will always provide for her. Later, when he breaks the literal promise by getting dysentery (a humorous detail), it underscores that the true promise—emotional devotion—remains intact. It also sets up the idea that some promises (like accepting her crime) are absolute.
How does the father’s own criminal past parallel Ella’s actions?
Answer: He served time for assaulting a man who wronged him by sleeping with his girlfriend. Ella burned her mother alive for years of abuse and neglect. In both cases, they took justice into their own hands against someone they believed deserved punishment. The father’s final line—“When someone deserves bad things, it’s sometimes up to you to dispense justice”—explicitly endorses this parallel.
