Summary

Tom leads Joan, Aaron, Ruth, and Frankie through the frozen, suspended halls of Whitehall Palace. The rooms are eerily still—letters lie on desks, beds are rumpled, and the Thames outside is motionless under moonlight. Ruth voices a growing unease, sensing that something is fundamentally wrong. Aaron, too, feels the timeline itself is disturbed. Tom explains that the King is never seen; he sends Court members like Conrad or Eleanor in his place. The group descends a staircase toward the Royal Archive, where Tom silently disables four guards.

They reach a passage blocked by a strange barrier: a slice of Paleolithic winter, complete with a saber-toothed tiger, that acts as a moat around the archive. Joan theorizes that the Hunt power—which places objects somewhen rather than somewhere—could bridge the gap. Ruth, though doubtful, pushes a rolled rug through the barrier, creating a tunnel. The group crawls through, enduring intense cold, and arrives at the archive door.

The door is locked, but the keyhole is sealed with a metal plate, making it unpickable. In frustration, Joan slams her hand against the door, and a latent ability awakens: she turns the lock to stone, cracking it open. Inside, they find not a treasure-filled archive but a vacant prison cell—bloodstains, scuff marks, and a thin mattress. Joan discovers a hidden object under the desk and pockets it. Ruth struggles to hold the tunnel open, and they barely escape before new guards arrive, leaving the rug behind as evidence.

Character Development

Joan undergoes a pivotal transformation. Her Hunt power has faded over the years, but she demonstrates sharp problem-solving by theorizing the tunnel bridge. More crucially, her latent ability—the power to turn metal to stone—awakens in a moment of desperation. This echoes Gran's warning that Joan would come into an ability she could trust no one with. Joan also shows resourcefulness by finding the hidden object, and her determination to save her family drives her to push forward despite the danger.

Ruth is initially doubtful and uneasy, but she rises to the challenge. Her Hunt power proves more versatile than anyone expected, as she holds the tunnel open with visible strain. Her earlier sense of wrongness proves prophetic, and she ultimately saves the group by maintaining the bridge.

Aaron displays fear and pragmatism, urging retreat when the barrier seems impassable. He is visibly terrified during the crossing, but he also shows respect for Ruth's power afterward, acknowledging that the Olivers underestimated the Hunts. His wariness of Joan's new ability hints at future tension.

Tom remains a steady guide, though his knowledge has limits—he didn't know about the barrier or the prison cell. He is focused on the mission, but his frustration at finding nothing in the archive reveals his own hopes and disappointments.

Themes, Symbols, or Motifs

Frozen Time: The entire palace is a stolen moment, with the Thames motionless and rooms suspended. This symbolizes the King's power to halt time itself, and the wrongness Ruth feels reflects the unnaturalness of such an act.

Time as Barrier: The Paleolithic moat is a literal wall of time, costing a hundred thousand years to cross each way. It underscores the immense cost of time travel and the King's willingness to use time as a defense.

The Hunt Power as Time Manipulation: Joan's realization that the Hunt power places objects somewhen rather than somewhere redefines the family's ability. The tunnel bridge demonstrates that time can be shaped, not just traversed.

The Archive as Prison: The room that should hold treasures is a cell, suggesting that the King's true collection may be prisoners, not objects. The bloodstains and scuff marks imply a violent struggle, and the hidden object hints at a secret left behind.

The King's Invisibility: Tom's explanation that the King is never seen reinforces the King's mysterious, almost godlike nature. His power is felt everywhere, but he himself remains absent, adding to the sense of dread.

Cost of Time Travel: The chapter repeatedly emphasizes the price of time manipulation—the four hundred thousand years a round trip would cost, the strain on Ruth, and the risk of being stranded. This motif highlights the moral and physical toll of the characters' quest.

Why This Chapter Matters

This chapter is a turning point in the novel. It reveals Joan's second ability, which Gran warned her to keep secret, and sets up a major mystery: what is the object she found, and who was imprisoned in the archive? The subversion of expectations—finding a prison instead of treasures—deepens the intrigue around the King and his true motives. Ruth's prophetic unease also foreshadows larger revelations, and the group's narrow escape raises the stakes for the rest of the story.

Study Questions and Answers

1. How does Joan's understanding of the Hunt power evolve in this chapter?

Joan initially believes the Hunt power places objects somewhere, but she realizes it actually places them somewhen—in a specific moment in time. This insight allows her to theorize that a tunnel could be created through the barrier, and Ruth's success proves the concept. This redefinition of the power has broader implications for the Hunt family's abilities and their role in the story.

2. What does the discovery of the prison cell instead of the archive suggest about the King?

The cell implies that the King's true collection may be prisoners, not treasures. The bloodstains and scuff marks suggest a violent struggle, and the hidden object hints at a secret the King wanted to keep. This challenges the group's assumptions and suggests the King's power is more sinister than they imagined.

3. Why does Joan's latent ability awaken at this particular moment?

Joan's ability awakens when she is desperate and frustrated, slamming her hand against the locked door. This aligns with Gran's warning that Joan would come into an ability she could trust no one with. The timing suggests that strong emotion—especially desperation—triggers the power, and it also marks a shift in Joan's identity as she discovers a part of herself she didn't know existed.
