Summary

Chapter 29, titled “Jack,” is a letter written by Cassidy (Jack) to Sundance (Rob). She opens by admitting she has drafted this letter many times, uncertain whether to give it to him, and reflects that the truth does not always bring freedom.

Cassidy then reveals the origin of the phrase “puppy farm.” Lina and Burt, the couple who raised them, used it as a joke about their many dogs, but in reality it was the name for the place where they kept children in cages. At first there were other children—some Lina’s own, some street kids they had picked up in cities. Cars would occasionally come, and people would look at the children; sometimes the cars took children away. Jack and Rob were never taken because they bit anyone who touched them.

Life in the cages was brutal. Food and water were scarce, and the children fought over scraps, which Burt found amusing. Jack recalls the yard with racks of drying hides and something hanging in a barn wrapped in cheesecloth, turning in the barred sunlight—an image that suggests something sinister.

As time passed, Lina and Burt began making meth, stopped sleeping, and stopped feeding the children. The number of children dwindled; one jumped into a well trying to escape. Eventually only Jack and Rob remained. There was an old teddy bear without eyes in the bottom of one cage, which Jack desperately wanted but could not reach.

Burt died of an overdose, and Lina left his body on the floor. She was hallucinating, talking to people who weren’t there. When she came to open the cage, Rob killed her with a piece of wire, believing she intended to eat them.

The two escaped into the desert, sunburned and sick, their eyes unaccustomed to light. They saw silver fences in the distance and walked toward them, thinking they were cages. Mia found them at the edge of the west run. They were ill for a long time.

A truck driver later discovered the puppy farm, and police found the other children dead. No one guessed that two had escaped. Jack reflects that children are mirrors, reflecting everything that happens to them, and warns Rob to remember that if he ever has children.

Falcon and Mia figured out what Jack and Rob were and saved them. But Rob, unable to escape the puppy farm in his mind, attacked Mia with wire and Jack with a screwdriver. To stop him, they gave both children “the click,” a procedure that made them “good dogs.” Jack was glad Rob would be safe, knowing what happens to bad dogs.

Afterward, Rob had no memory of the past. Jack gave him replacement memories, including a mother, and she sometimes believed them herself. Falcon, Mia, and Pawel also hid the truth in their own ways. They fear that a grad student or someone in town might reveal the truth to Rob, or that he might find an old newspaper. So far, secrets have stayed hidden in the desert.

Jack believes Rob is determined not to remember, pushing the past down into the dark. She thinks that is good. When the click began to go wrong for Jack, Falcon told her she could never leave Sundial. She agreed, and she now plans to tell Rob enough of the truth to make him hate her, so he will leave without her.

The puppy farm still stands in the foothills of the Cottonwoods, visible from the stone garden. People have set up a camp there, and they supply Pawel with what he needs to keep the bad click under control—a full circle, as Jack notes.

Finally, Jack reveals that Lina and Burt’s real names were Jacqueline and Robert Grainger. She knows Rob keeps that knowledge somewhere inside him, because he named them Rob and Jack after those names.

Character Development

Cassidy (Jack) emerges as a deeply protective and self-sacrificing figure. She has carried the burden of the truth alone, crafting replacement memories for Rob and shielding him from the horror of their past. Her decision to make Rob hate her so he will leave Sundial shows her willingness to sacrifice their relationship for his safety. She also demonstrates a clear-eyed understanding of the world: she knows what happens to “bad dogs” and is glad Rob was made “good,” even at the cost of his true memories.

Sundance (Rob) is portrayed through Jack’s eyes as someone who has repressed his trauma so completely that he has built a new identity. His violent past—killing Lina and attacking Mia and Jack—is hidden from him, and he now lives as a “good dog.” Jack’s letter implies that Rob’s determination to forget is itself a form of survival, but it also sets up the central conflict of the novel: the truth will eventually surface.

Falcon and Mia are shown as saviors but also as manipulators. They saved Jack and Rob from the desert, but they also imposed the click, erasing Rob’s memories and controlling Jack’s future. Their decision to forbid Jack from leaving Sundial reveals a paternalistic, almost possessive attitude toward the children they rescued.

Lina and Burt are revealed as monstrous figures, but their real names—Jacqueline and Robert Grainger—connect them to the next generation, suggesting a cycle of trauma and naming that Jack and Rob cannot escape.

Themes, Symbols, or Motifs

Truth vs. Protection: Jack’s letter is a meditation on whether the truth frees or harms. She withholds it from Rob to protect him, but also plans to use it to drive him away.
Memory Suppression: The click is a literal erasure of memory, but Jack also engages in voluntary suppression by giving Rob replacement memories. The theme questions whether forgetting is a form of healing or a denial of identity.
Names and Identity: The revelation that Lina and Burt were Jacqueline and Robert Grainger, and that Rob and Jack are named for them, suggests that names carry the weight of the past. Jack’s own name change from Jack to Cassidy further complicates identity.
Good Dogs/Bad Dogs: The metaphor of dogs recurs throughout the chapter. The click makes children “good dogs,” implying obedience and docility, while “bad dogs” are those who resist or remember. This binary frames the children’s survival.
The Full Circle: Jack notes the irony that the puppy farm now supplies Pawel with what he needs to control the click. The site of their trauma has become a source of ongoing control, completing a cycle of abuse and dependence.
The Teddy Bear: The eyeless teddy bear in the cage represents lost innocence and the unattainable comfort of childhood. Jack’s inability to reach it mirrors her inability to escape the past.
The Wire: The wire is both the instrument of Lina’s death and a symbol of the violence that defines Jack and Rob’s survival. It also connects to Rob’s later attack on Mia.

Why This Chapter Matters

This chapter is the emotional and narrative core of the novel. It provides the long-awaited backstory that explains the children’s trauma, the origin of the click, and the reason Jack is so fiercely protective of Rob. It also sets up the central conflict for the remainder of the story: Jack’s plan to make Rob hate her so he will leave Sundial. The revelation of the puppy farm’s continued existence and its connection to Pawel adds a layer of irony and horror, suggesting that the past is never truly buried. Finally, the chapter deepens the theme of identity by linking the children’s names to their abusers, implying that they are forever marked by their origins.

Study Questions and Answers

1. Why does Jack decide to tell Rob the truth, even though she has spent years hiding it?

Jack’s decision is driven by Falcon’s command that she can never leave Sundial. She realizes that Rob will not leave without her, so she must make him hate her to force him to go. The truth becomes a tool to sever their bond, sacrificing her own happiness for Rob’s safety. She also acknowledges that the truth doesn’t always set you free, but in this case, it may be the only way to free Rob.

2. How does the chapter use the metaphor of “good dogs” and “bad dogs” to explore trauma and control?

The metaphor frames the children as animals that can be trained. The click turns them into “good dogs” by erasing their memories and violent impulses, while “bad dogs” are those who resist or remember. This binary suggests that survival requires obedience and forgetting, but it also dehumanizes the children, reducing them to conditioned responses. Jack’s awareness that she knows “what happens to bad dogs” implies a fear of punishment or death for those who don’t conform.

3. What is the significance of the revelation that Lina and Burt’s real names were Jacqueline and Robert Grainger?

The names connect the abusers to the next generation: Rob and Jack are named for them. This suggests that the children are forever tied to their abusers, even in their identities. It also implies a cycle of trauma—the names carry the legacy of violence, and Jack and Rob cannot escape it, no matter how hard they try to forget. The naming may also be a subconscious act of remembrance on Rob’s part, as Jack notes he “keeps that in there somewhere.”
