Summary

At four thirty in the afternoon, the bookmobile arrives at Wellwood House. Fern watches from the Cong window, dreading the encounter. With Zinnia and Holly, she waits until the pregnant Jasmine departs before walking to the bus. They plan to return their library books and hope the librarian, Miss Parcae, won't ask about the missing spellbook Groovy Witch.

Miss Parcae greets them calmly, stamps the returned books, and mentions that this is their last visit of the summer. Relieved, Fern turns to leave, but Miss Parcae asks if they know anything about the recent strange weather—rain on clear days—revealing she suspects they used the book. Fern admits they tried but failed, and that Holly even tried to learn the craft without success. Miss Parcae insists on getting the book back, but Fern confesses it was burned by Hagar, the Home's cook. The librarian is furious, calling Fern careless and selfish.

After a moment of pain—Miss Parcae reveals she is dying of liver cancer. She tells Fern that she needs to pass on her power and the memories of three thousand years of witches—the line of Hecate—into a new vessel. Fern is the chosen one because she read the book. Fern refuses, terrified of losing her identity. Miss Parcae reminds her of the vow they made, and threatens to force the transfer involuntarily.

Zinnia steps in and the three girls flee from the bus back to the Home. In their room, Fern explains everything: the witch line, the cancer, and the plan to replace Fern's mind. Holly asks if Fern can do it for her, but Fern cannot. Zinnia concludes they must tell Hagar.

After dinner, they approach Hagar in the kitchen. Upon hearing the story, Hagar takes action. She retrieves a chest of silverware and has Fern help her bury sixteen pieces of silver in the four corners of the front and backyards. Silver, Hagar explains, is clean metal that witches cannot cross. She also nails horseshoes over the back and side doors while Miriam tends to the front.

That night, the girls stay together in Fern's room. Holly and Fern share the bed; Zinnia stays awake. As the wind picks up, Fern sees trees full of witches—women riding the branches, naked, surrounding the Home. At the edge of the yard, Decima emerges from the woods, sniffs, and sits at the silver boundary. She does not cross.

Character Development

Fern: Faces a choice between self-preservation and a self-sacrificing promise. Her refusal to accept the transfer shows growth in asserting her own will and fear of losing her identity.
Zinnia: Emerges as a protective leader, physically placing herself between Fern and Miss Parcae. She coaxes the truth from Fern and orchestrates the plan to tell Hagar.
Holly: Remains driven by her need for a cure but respects Fern's refusal. Her question—"You can't do it? For me?"—underscores her desperation yet willingness to accept Fern's decision.
Miss Parcae: Revealed as desperate and dangerous, willing to override consent. Her calm facade breaks, exposing the predatory nature of the witch line.
Hagar: Takes immediate, practical action, demonstrating occult knowledge and a protective instinct toward the girls despite her earlier gruffness.
Miriam: Assists Hagar without hesitation, reinforcing their close bond and shared history with the supernatural.

Themes, Symbols, or Motifs

Consent and Bodily Autonomy: Miss Parcae tries to force the transfer, while Fern repeatedly says no. The chapter contrasts voluntary sacrifice with coercion.
Containment vs. Threat: Silver and iron are used to create a safe space. The barrier symbolises the line between personal agency and external predatory forces.
The Price of Power: Every magical bargain carries a cost—Fern's vow is claimed as binding, and the librarian insists the debt must be paid.
The Body as Vessel: The witch line requires a living human host; Fern's fear is of being replaced by the accumulated souls of past witches.
The Home as Fortress: The girls and Hagar fortify the building, turning it from a prison into a defensive shelter.

Why This Chapter Matters

This is the turning point where the supernatural threat becomes overt and personal. Fern's refusal aligns her with self-determination over magical convenience, setting up the final conflict. It also reveals the true nature of Miss Parcae's offer—not empowerment but a form of identity theft. Hagar's intervention shows that the girls are not alone and that practical folk protections can counter old magic. The chapter raises the stakes and clarifies the central moral conflict: what are you willing to sacrifice for someone else?

Study Questions and Answers

1. Why does Miss Parcae specifically target Fern to be her successor?
Fern is the only one who read the entire spellbook and passed the test of magical potential. With the book destroyed, Miss Parcae cannot find another candidate, and Fern's ability to understand the craft makes her the last viable vessel.

2. What does Hagar's knowledge of silver and horseshoes reveal about her background?
Hagar knows exactly how to ward against witches—burying silver at corners and nailing iron horseshoes. This suggests she has encountered supernatural threats before, likely from her own past experiences at the Home or elsewhere, making her an unexpected ally.

3. How does the chapter reinforce the theme of selfhood and identity?
Fern's terror at having her mind overwritten mirrors the novel's broader concern with losing oneself—whether through motherhood, institutionalization, or supernatural possession. Her repeated "No" asserts her right to remain Fern.
