⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.
Summary
Two years before the main events of the novel, Erin discovers she is pregnant. After taking multiple home tests, she stares at the positive results in a state of numbness, unable to process the implications. She confides in Senna during a café meeting, revealing that she has only had sex once that year, making her roughly a month along. Senna gently points out that an abortion is still possible, and Erin admits she is uncertain, saying she will “probably” consider it but doesn't know.
Erin's internal voice questions why she is telling Senna instead of a GP or her mother. The answer, though difficult to accept, is that she needs the Triskele's approval before acting. She has come to rely on the group's guidance because they claim to possess the Truth, and she views them as a watchtower overlooking the maze of life.
A week later, Erin meets the Brother at a derelict castle in the Trossachs. Walking through an old drawing room, he tells her that her baby is “very, very special” because no child has ever been conceived during the Beltane ritual. He claims that a child born to someone living beyond the Boundary is incredibly gifted. He takes her hands, expresses his happiness for her, and she feels a deep longing for him to adopt her. He tells her she should keep the baby, and when she asks about telling Arlo, he says it is entirely her choice.
As they walk, Erin notices the castle's ruined state—a tree growing through a window frame, an intact stone mantelpiece—which reminds her of her grandparents' cottage on the Isle of Mull. She recalls her grandmother calling her a “little bean” and the loss of both grandparents when she was nine. A voice in her head tells her she is too young to have a baby, but another voice counters that the baby will give her a bigger family.
The Brother then reminds her of two things. First, the Triskele is her family. He says they are there for her and the baby, and Erin feels a sob rising as she thanks him. Second, he extends an invitation: he wants to give her the dark book with black pages, which he had mentioned during her training. He insists that her conception on Beltane is no accident, calling it her destiny and describing her child as a “fire god or goddess of the natural world.” He tells her she is amazing and that this is her journey to the Truth.
He leads her to his car and opens the boot, revealing the book wrapped in a blanket. He seems nervous as he asks her to take it. She hesitates, wondering why she should be the one to hold it, especially since many other initiated members exist. The Brother's tone shifts abruptly. He reminds her that she received her scholarship for free and says, “The least you can do is take this thing out of my fucking hands.” Erin reels at his sharpness, having just seen him as a jolly, fatherly figure. She tightens her hold on the book and agrees. He smiles, but it is an odd, broken smile, and he wishes her good luck.

Character Development
Erin is portrayed as deeply vulnerable and dependent on the Triskele for guidance. Her internal conflict—wanting to act independently but feeling compelled to seek the group's approval—reveals how thoroughly the cult has infiltrated her decision-making. Her nostalgia for her grandparents' cottage highlights her longing for a stable family, which the Triskele exploits. Her acceptance of the book, despite her misgivings, shows her inability to resist the Brother's coercion.
Senna acts as a conduit between Erin and the Brother, but her role is ambiguous. She offers practical advice about abortion, yet she also suggests involving the Brother, indicating her own allegiance to the cult.
The Brother displays a dual nature. Initially, he is warm, paternal, and seemingly supportive, calling Erin “amazing” and expressing joy. But when Erin questions his request, his tone becomes sharp and threatening, revealing a manipulative core. His use of guilt—reminding Erin of her scholarship—demonstrates how he leverages obligation to control her.
Themes, Symbols, or Motifs
-
Destiny vs. Choice: The Brother frames Erin's pregnancy as fate, insisting that conception during Beltane is a sign of destiny. This narrative strips Erin of agency, positioning her as a vessel for a prophecy rather than a person with choices.
-
Manipulation and Coercion: The chapter illustrates how the Triskele uses emotional and psychological pressure. The Brother's shift from fatherly warmth to sharp anger is a classic manipulation tactic, and his reminder of the scholarship is a direct appeal to guilt.
-
The Dark Book as a Burden: The book with black pages symbolizes the cult's secrets and the weight of responsibility they place on Erin. Her reluctance to take it, and the Brother's insistence, foreshadow the danger it will bring.
-
Surrogate Family: Erin's longing for family—her dead grandparents, her absent father—makes her susceptible to the Triskele's claim that they are her family. The Brother's fatherly demeanor fills a void, but it is a false comfort.
-
The Boundary and the Beltane Ritual: The chapter reinforces the mystical significance of the Boundary, suggesting that crossing it during Beltane has supernatural consequences. This ties Erin's pregnancy to the novel's larger occult framework.
Why This Chapter Matters
This chapter is pivotal because it sets Erin on a path that will define the rest of the novel. Her decision to keep the baby, influenced by the Brother's prophecy, creates the central conflict of her life. The dark book becomes a tangible object that will later resurface, and the Brother's manipulation establishes the Triskele's true nature. The chapter also deepens our understanding of Erin's psychology, showing how her need for belonging makes her vulnerable to exploitation. It is a turning point where she surrenders her autonomy, setting up the tragic events that follow.
Study Questions and Answers
1. Why does Erin tell Senna about her pregnancy instead of a doctor or her mother?

2. How does the Brother manipulate Erin into accepting the dark book?
The Brother first frames the book as a privilege, linking it to her special pregnancy and destiny. When Erin hesitates, he shifts to guilt, reminding her that she received her scholarship for free and implying she owes him. This combination of flattery and obligation leaves Erin no room to refuse.
3. What does Erin's reaction to the Brother's sharpness reveal about her character?
Erin is shocked when the Brother's tone turns harsh, because she has idealized him as a father figure. Her reeling reaction shows how much she craves his approval and how unprepared she is to see his manipulative side. It also highlights her emotional fragility and the power imbalance in their relationship.
