Chapter Summary

Still processing the revelation that she is not a warlock, Kierse returns to the Holly Library with Graves. She had hoped her unknown powers would mean easy magical training; now she fears for her survival on the upcoming heist. Graves invites her to ask questions, and Kierse pushes past her disappointment to demand facts.

Graves explains that her earlier immunity was actually absorption – the magic of the wards entered her skin rather than being repelled. He speculates that she might store the magic for later use. Kierse then realizes her instinctual "slow motion" ability (seeing opponents in delayed time) was likely a natural magical power she has used her whole life without knowing it.

Graves removes his gloves and demonstrates his own primary ability: reading. By touching someone, he can skim their surface memories and deep desires. He admits he tried to read Kierse when she was unconscious from wish powder; he glimpsed a violent memory that he dismisses as a hallucination – though Kierse recognizes it as the night Jason nearly killed her. Graves theorizes that the overdose of absorbed magic weakened her defenses, allowing him to read her.

Together they conclude that stealing is the activity that recharges Kierse’s magic – the one thing that always made her feel stronger. Graves decides to change their strategy: instead of training a passive immunity, he will teach her to actively absorb the wards surrounding the vault, so that he can accompany her to the solstice party. He introduces the fundamentals of warding as an application of intent. Kierse tries repeatedly to seal a wooden box with a ward but fails. Graves tells her to keep the box and practice.

The chapter ends with Graves announcing that they will conduct reconnaissance that night – in the underworld.

Character Development

Kierse faces an identity crisis upon learning she isn’t a warlock, but she quickly rebounds with practical resolve. Her recognition that stealing defines her and fuels her magic reinforces her self-concept as a survivor and a thief. She also shows growing trust in Graves, allowing him to keep his gloves off around her.

Graves reveals vulnerability by sharing the mechanics of his reading ability and his past failed attempt to read Kierse. His willingness to adapt the heist plan – and to accompany her in person – signals a deepening personal investment beyond the job. The removal of his gloves is both a literal and symbolic gesture of intimacy.

Kingston is mentioned only in Graves’ backstory as his mentor and the owner of the art-powered magic. He remains an off-page influence.

Themes, Symbols, or Motifs

Identity vs. Discovery: Kierse’s magical nature is not what she expected, yet she embraces the thief identity as the source of her strength.
Trust and Vulnerability: Graves removes his gloves, a high-risk gesture for someone who uses touch to read others. Kierse chooses not to ask about the memory he saw.
Magic as Intent: Warding is introduced as an act of will, not an inherent talent – a democratizing concept that opens possibilities for Kierse.
Transformation of Weakness: The absorption ability, initially seen as a dangerous anomaly, is reframed as a strategic asset for the heist.
The Underworld: Introduced as a setting for reconnaissance, the underworld hints at the moral grayness of the characters’ world.

Why This Chapter Matters

This chapter marks a turning point in Kierse’s understanding of her powers and her relationship with Graves. The shift from immunity to absorption transforms the heist strategy and sets up a new training arc. Graves’ disclosure of his reading ability deepens their bond and raises stakes for mutual trust. The chapter also explicitly links Kierse’s thieving past to her magical future, solidifying her core identity as a thief. Finally, the promise of underworld reconnaissance expands the story’s world-building.

Study Questions and Answers

1. How does Kierse’s magical nature differ from what she and Graves assumed? Answer: They believed she was a warlock with passive immunity to magic. Instead, she has the ability to absorb magic into her body, and this absorption was mistaken for immunity.

2. What activity does Kierse realize restores her magical energy, and why is that significant? Answer: Stealing recharges her magic. This matters because it confirms that her lifelong habit of picking pockets is not just survival but also a natural magical practice, tying her identity directly to her power.

3. Why does Graves decide to change the plan for obtaining the spear? Answer: Since Kierse can absorb rather than repel magic, Graves believes she can be trained to absorb the wards around the vault, enabling him to accompany her to the solstice party and increasing their chances of success.
