Summary

After a terrifying moment when Callie nearly slips into an abandoned mine shaft, Rob drives her to Sundial, the remote desert property where she grew up. The journey is tense; Rob’s mind is still reeling from the scare and from the discovery of a bone portrait in Callie’s bag—evidence that Callie killed a puppy. As they pass through the gate into the fenced compound, Rob notes the decaying outbuildings, the padlocked laboratories she gutted years ago, and the human sundial that gives the house its name.

At the front door, Callie asks about the wooden sign reading “NO DOGS IN THE HOUSE.” Rob explains that the dogs they had were not pets. Inside, the familiar scent of warm wood and stale air greets them, but Rob is overwhelmed by the memory of the bone picture. She imagines the puppy’s death in vivid, horrifying detail, and Jack’s voice echoes in her head: “There’s a dog in the house.”

Rob makes pizza and texts Irving, instructing him to throw out everything hanging on Callie’s walls. She wants him to feel the shock of discovering the little bones. Stepping outside, she contemplates the two headstones she placed near the house, under the jacaranda tree, marking graves that hold no bodies—her mother’s and another’s. Callie joins her for dinner, and Rob reflects on her unusual childhood, raised by her father Falcon in this isolated place. She recalls how she used to try to make her upbringing sound normal to others, but eventually realized that her experiences—including a serial killer for a parent—set her apart.

Later, Rob calls Irving. He claims he has cleaned Callie’s room, but Rob knows he is lying. Hannah comes on the line and reports that Annie’s fever is improving. Rob hangs up, then goes to say good night to Callie, who is kneeling by her window, counting stars like any ordinary child.

Character Development

Rob is consumed by maternal fear. The chapter opens with her heart pounding from the mine shaft incident, and she admits to herself that she wonders if she can only keep one of her children. This internal conflict—choosing between Callie and Annie—becomes a central tension. Rob’s reaction to the bone portrait reveals her horror and guilt; she blames herself for teaching her children “how to scream in silence.” Her memories of Sundial show a woman caught between two selves: the old Rob who died here and the mother she has tried to become. She is determined to “leave parts of Callie here” as well, suggesting she sees Sundial as a place of transformation or purging.

Callie is portrayed as both innocent and unsettling. She asks childlike questions about the sign, worries about her mother’s health, and counts stars at the window. Yet her calm admission that she has a puppy “already” and her attachment to the bone portrait hint at a darker nature. Rob’s observation that Callie is “still a child” underscores the ambiguity.

Irving is absent but present through Rob’s phone call. He lies about cleaning Callie’s room, and Rob’s decision to punish him by making him discover the bones shows her anger and distrust. Hannah appears as a caring presence, offering comfort to Rob about Annie’s condition, though Rob withholds the task of cleaning the room from her, reserving that punishment for Irving.

Themes, Symbols, or Motifs

Maternal fear and the choice between children: Rob’s recurring thought that she may have to choose between Callie and Annie drives the chapter’s emotional weight.
The desert as psychological landscape: Rob notes that “all that space gets in your head, makes your thoughts go crazy.” The desert mirrors her mental state—vast, isolating, and prone to dangerous imaginings.
Sundial as a place of memory and trauma: The house is described as a wheel, with memories lying in the stone floors. Rob feels the ghost of her old self here, and the property itself becomes a character.
The bone portrait as a symbol of violence: The tiny bone picture represents Callie’s capacity for harm and the loss of innocence. Rob’s vivid imaginings of the puppy’s death amplify the horror.
Normal vs. abnormal childhood: Rob’s reflections on dinner-party conversations highlight how her upbringing—homeschooled by a father named Falcon, with a serial killer parent—sets her apart from ordinary experiences.
Memory as a noose: Rob describes memory as a noose that tightens, triggered by sensory impressions like scent or sound. This motif underscores the inescapable past.
The house as a character: Sundial is described in detail—its round shape, massive stone blocks, and the human sundial—making it a living, oppressive presence.

Why This Chapter Matters

This chapter establishes Sundial as a central setting and a repository of Rob’s past. It deepens the mystery of Callie’s actions by introducing the bone portrait and Rob’s fear that Callie may harm Annie. Rob’s internal conflict about choosing between her children sets up the novel’s central dilemma. The chapter also reveals key details about Rob’s childhood—her father Falcon, the coyote pup, the rattlesnake den—and her struggle to reconcile her past with her present. The phone call with Irving and Hannah introduces the subplot of Annie’s illness and Rob’s distrust of her husband, while the final image of Callie counting stars offers a moment of poignant normalcy that contrasts with the darkness surrounding her.

Study Questions and Answers

1. Why does Rob bring Callie to Sundial despite the danger and her own traumatic memories?

Rob believes Sundial is the only place where she and Callie can “work things out.” She wants to leave parts of Callie there, just as she left parts of herself. The isolation of the desert property provides a controlled environment where Rob can confront Callie’s behavior without outside interference.

2. What does the bone portrait reveal about Callie, and how does Rob react to it?

The bone portrait is evidence that Callie killed a puppy. Rob is horrified and imagines the death in graphic detail. She blames herself, wondering if teaching her children to “scream in silence” led to this violence. The portrait also makes Rob fear that Callie might hurt Annie, intensifying her maternal anxiety.

3. How does Rob’s childhood at Sundial shape her view of normalcy and her relationship with her own children?

Rob’s upbringing was far from ordinary—homeschooled by her father Falcon, with a serial killer parent and no typical childhood experiences. She learned to hide her differences in social settings, but the memories still haunt her. This background makes her hyperaware of her children’s behavior and fuels her fear that Callie might inherit a dangerous legacy.
