The Climax Explained
The chapel confrontation resolves the novel's central mysteries in a single, pressure-cooker scene.
The truth about Lily-Anne. Josephine reveals that Lily-Anne conceived alone, giving birth to a tenth Girl who died, and that Bellanger hid the evidence. This revelation reframes Fiona's entire identity. She has been raised to believe her powers are Bellanger's creation, his legacy. Josephine's revelation shows her they are her own—and shared by all the Girls.
The confession. Fiona demands Bellanger admit he killed her mother. He confesses, saying, in effect, that Lily-Anne was standing in the way of everything. This is the moment Fiona's allegiance shifts. Her flames, which she has been trained to control, erupt beyond her command, and the chapel begins to burn.
The sacrifice and revival. Bellanger shoots at Josephine, but Margaret steps in front of the bullet. Cate and Fiona together revive her—a demonstration of the collective power Josephine has been insisting on throughout the novel. The Girls are not Bellanger's miracles; they are their own.
The final command. Josephine commands Bellanger to walk into the flames and stay there. He obeys, walking deeper into the fire as the roof collapses. This is a deliberate inversion of Bellanger's role as creator: the man who sought to own the Girls' lives is consumed by the fire his own legacy ignited.

She has also reconciled with her mother, who now knows who Josephine is and what she is capable of.
Margaret Morrow
Margaret's disappearance at the novel's start is revealed to be part of a larger reckoning with Bellanger. She takes a bullet meant for Josephine and dies—briefly. Cate and Fiona together revive her. The novel's final image of Margaret is one of reconciliation: she and Josephine share an understanding, and she has a quiet moment with Isabelle, who calls her
