Summary

The chapter opens in December 1961, with Beth recalling that Lily kept her promise and returned to the Greer mansion every Christmas. The pattern was predictable: as winter darkness set in, Mariana's mood would spiral, her drinking would increase, and arguments with Julian would escalate—arguments Beth could hear from her bed, aware that her parents believed they were hiding their unhappiness by arguing after she was supposedly asleep.

Then Mariana would become excited about Christmas, convinced it would solve her problems. She'd buy stacks of decorations she never put up, seek out the biggest tree, and invite Lily. Lily always came, sleek and composed, and she and Julian would engage in silent staring contests until Julian packed a bag and left the house.

Beth learned early that she needed both Julian and Lily for survival, so she developed strategies to appease both. She never mentioned Lily in Julian's presence, because doing so would make him leave the room. When she tried once to convince Lily that Julian was kind, Lily responded with a flat, dead-eyed remark about being left to die like a stray dog. Beth never brought it up again.

Some Christmases, Mariana left too, and the girls were alone together. They watched television and competed in cartwheel competitions on the back lawn, with Lily always pushing closer to the edge of the drop than Beth could bear, teaching Beth to suppress her fear.

Other Christmases, Mariana stayed. She'd play board games and bake cookies, pretending Christmas was cheerful. She told a recurring story about two little girls kidnapped by an evil witch—one bitter, one sweet. Beth always wanted to be the sweet girl, but she understood the story's unspoken ending: the sweet girl gets eaten, the bitter girl survives.

Lily became Beth's best and only friend. She taught Beth social manipulation—when to fight, when to suck up, when to flirt. When Beth was ten and boys at school began bullying her, Lily explained it was because she was pretty and told her being a girl was an advantage because no one ever believes a girl would do something bad. That night, they snuck out and wrote swear words on the school wall with Beth's hopscotch chalk. When school resumed, the boys were questioned and two got in trouble. No one questioned the girls.

The Christmas Beth was twelve and Lily was fourteen, Mariana stayed home. They played Snakes and Ladders while Mariana drank through the entire game, ending up drunk and passed out. As the girls helped her to bed, Beth studied Lily's face and saw Mariana's features mirrored there. She asked Lily if her parents were really dead. Lily said no—that was a lie Mariana told. Beth said the words that changed everything: our mother.

Lily explained that Mariana brings her every Christmas out of guilt for abandoning her, then does it all over again. She confirmed Julian is not her father, that she doesn't know who her father is, and that she plans to find out. Lily said she wants the house. Beth said she hates it. Lily called it an abomination that shouldn't exist, and said it was exactly like her.

Beth wanted to tell Lily to get away from her mother, but she realized she needed Lily—needed all three of them, actually, to get through each year, but Lily most of all. So she said the one thing she knew would keep Lily on her side: she wanted to be like her. Lily smiled.

Character Development

Beth — This chapter shows Beth's survival instincts developing. She learns to manage three volatile relationships (Julian, Mariana, Lily) and to suppress her fear. Her realization about Lily's parentage is a turning point: she feels excitement, dread, guilt, and shame, but also recognizes her own need for Lily. Her final declaration—that she wants to be like Lily—is both a genuine desire and a calculated move to keep Lily close.

Lily — Lily's flat, dead-eyed affect is consistent throughout. She's pragmatic about her abandonment, unemotional about the revelation, and focused on her goals: finding her father and getting the house. Her description of the house as an abomination that shouldn't exist reveals how she sees herself.

Mariana — Though mostly passive in this chapter, Mariana's pattern is fully exposed: guilt-driven Christmas gestures, drinking, and abandonment. The bitter and sweet girl story suggests she sees her daughters through a reductive binary.

Julian — Present only through his absence—he leaves whenever Lily arrives, revealing the depth of their conflict.

Themes, Symbols, or Motifs

Christmas as false hope — Mariana's annual conviction that Christmas will solve her problems is undercut by the reality: she buys decorations she never puts up, drinks through games, and abandons her children.

The bitter vs. sweet girl dichotomy — Mariana's story about the witch's victims encodes the chapter's central insight: sweetness is a liability, bitterness is survival. Beth knows the sweet girl gets eaten.

Gender-based invisibility — Lily's lesson that girls are never suspected of wrongdoing is proven by the school wall incident, where boys are blamed for the girls' crime.

The house as abomination — Lily's identification with the house—an abomination that shouldn't exist—links her self-conception to the Greer mansion's dark history.

Maternal abandonment — Mariana's pattern of abandoning Lily, then feeling guilty, then repeating the cycle, is laid bare.

Why This Chapter Matters

This chapter is the emotional core of Beth and Lily's relationship. It reveals the half-sister connection that explains Lily's presence in the Greer household and establishes the dynamics that will shape both women's futures. Lily's stated goals—finding her father and claiming the house—set up the central mysteries of the novel. Beth's decision to say she wants to be like Lily marks the moment she begins to emulate her sister, with consequences that likely ripple through the rest of the story.

Study Questions

1. Why does Beth tell Lily she wants to be like her, and what does this reveal about Beth?

Beth says it because she knows it's the one thing that will keep Lily on her side. She recognizes that she needs Lily for survival—more than she needs Julian or Mariana—and this is the calculated move that will bind Lily to her. It reveals that Beth has fully absorbed Lily's lessons in manipulation and is willing to use them, even on the person she loves most.

2. What does Mariana's bitter girl and sweet girl story reveal about her worldview?

The story, in which two girls are kidnapped by a witch and one is bitter while the other is sweet, suggests Mariana sees her daughters through a reductive binary. Beth's interpretation—that the sweet girl gets eaten and the bitter girl survives—reveals the story's dark subtext and Mariana's own survival instincts.

3. How does the school wall incident illustrate Lily's philosophy about being a girl?

Lily tells Beth that being a girl is an advantage because no one believes a girl would do something bad. The incident proves her point: the girls write swear words on the school wall, and the boys are questioned and punished. This demonstrates the gender-based invisibility that Lily exploits and teaches Beth to exploit as well.
