Graham Deming is the novel’s primary antagonist and a static character who embodies the oppressive and hypocritical nature of the patriarchal system Camille initially serves. He is controlling through condescension and financial dependency, positioning himself as a benevolent provider while systematically undermining Camille’s autonomy. He encourages her to quit her job, establishes a “monthly allowance,” and discourages activities he deems unfeminine, such as strength training, all under the guise of cherishing her natural beauty and traditional values. His interactions with Camille are marked by a patronizing tone; he often adopts a “pleased, teacherly quality” when he discovers something she does not know (52), reinforcing a power dynamic in which he is the knowledgeable authority, and she is the naive subordinate. This constant, subtle reinforcement of his superiority leaves Camille isolated and dependent on his approval, a key element of his control.

Graham’s character is defined by a deep hypocrisy that reveals the hollowness of the traditional values he espouses. While he expects Camille to be a perfect, devoted, and chaste wife, he is emotionally neglectful and physically unfaithful. His frequent late nights, the lingering scent of another woman’s perfume, and the eventual discovery of his secret Instagram account and affair with “Rose” expose his double standards. In his messages to Rose, he laments his marriage and even questions Sweetheart’s paternity, revealing a deep resentment for the very family life he claims to want. His commitment is to the image of a family and the power it affords him as its patriarch. This hypocrisy is the ultimate betrayal, acting as the final catalyst for Camille’s violent rejection of their marriage and the system he represents.

Ultimately, Graham is self-serving and oblivious, incapable of recognizing or caring about the big changes in his wife and child because they do not align with his needs. He notices superficial flaws, such as a messy house or a poorly cooked meal, but fails to recognize Camille’s deteriorating health, her monstrous transformation, or the non-human nature of their daughter. Even when confronted with Sweetheart’s unsettlingly rapid growth, his concern is fleeting and easily dismissed by Camille’s reassurances. His final confrontation with Camille reveals his true motivation: He is leaving Camille only because she is no longer the “sweet, innocent girl” who caters to his needs (293). His inability to adapt or show genuine empathy seals his fate, as he becomes the ultimate source of nourishment for the monstrous family he helped create but could never truly be a part of.

The creature is a supernatural catalyst and a symbolic figure representing a primal, alternative form of masculinity and existence. He is summoned by Camille’s wish at the well and serves as the agent of her conception, offering her a path to motherhood completely detached from the patriarchal constraints of her marriage to Graham. His nature remains ambiguous; Camille initially interprets his presence as angelic, a sign of divine intervention, before later understanding him as a fallen angel or demon. This ambiguity emphasizes his role as a force outside conventional morality. He communicates non-verbally, providing for Camille by leaving a steady supply of dead animals for her to consume. This act of nourishment is direct and instinctual, contrasting sharply with Graham’s conditional financial support. The creature’s connection to the well and the forest establishes him as an entity of the wild, untamed world that Camille ultimately chooses over her domestic prison.

Sweetheart is the physical manifestation of Camille’s monstrous transformation and the embodiment of the novel’s central themes. As the offspring of Camille and the creature, she is not fully human, a fact evidenced by her white eyes, reptilian teeth, unnaturally rapid growth, and primal hunger for flesh. Her very existence is a rejection of the “natural” family life Camille once sought. 

Sweetheart’s survival depends on a grotesque form of consumption, first feeding on pieces of Camille’s body and later on other humans. This dynamic redefines the maternal bond as a primal, symbiotic relationship built on mutual sacrifice and predation, a core tenet of the theme Motherhood as Monstrous Consumption. Because she is a product of a world outside patriarchal norms, Sweetheart cannot exist within them, and her presence necessitates the family’s ultimate retreat into the forest, solidifying their break from civilized society.

Renee Colt is a foil to Camille, presenting a chaotic and flawed version of stay-at-home motherhood that contrasts with Camille’s curated perfection. Where Camille is restrained and performative, Renee is loud, intrusive, and emotionally transparent. Her backstory reveals the potential consequences of the life Camille leads; having lost custody of her children and her home in a divorce, Renee shows a future Camille desperately fears. Renee’s persistent, prying questions about what Camille truly wants challenge Camille’s carefully constructed reality and force moments of uncomfortable self-reflection. Despite Camille’s annoyance, Renee is the only character who expresses genuine concern for her well-being. Ultimately, Renee’s tragic fate is to become the first human meal for Sweetheart, an act that pushes Camille past a moral boundary and solidifies the monstrous nature of her new maternal duty.

Mara Shoemaker is a symbolic antagonist and false mentor whose influence looms over Camille’s life. Though she never appears in person, her perfectly curated social media presence represents the unattainable ideal of the tradwife lifestyle that Camille strives to emulate. Mara’s online persona, built on aesthetic purity and a large, happy family, is the standard against which Camille measures her own success and failure. Mara’s dangerous anti-science advice and her transactional online interactions highlight the superficiality of the community Camille desperately seeks to join. Camille’s final, violent rejection of this ideal is directed squarely at Mara, signifying her liberation from the digital prison of performative femininity.
