Reach for this book when your child is struggling with outbursts, resentment, or the feeling that their 'dark' side is in control of their actions. It is an ideal choice for pre-teens navigating the isolation of a single-parent home or feeling misunderstood by peers. The story follows Jessica, a lonely girl who projects her own anger and manipulative impulses onto a stray cat she believes is possessed by a malevolent witch. This psychological mystery serves as a sophisticated metaphor for how young people process guilt and accountability. While it carries a spooky, suspenseful atmosphere, it ultimately offers a powerful lesson in self-reflection and the courage it takes to own one's actions rather than blaming external forces. It is best suited for mature readers aged 10 to 14 who enjoy complex characters and eerie, thought-provoking narratives.
A tense sequence involving a homemade ritual to 'cure' the cat.
Themes of profound loneliness and a mother who is emotionally distant and self-absorbed.
Atmospheric horror elements and the protagonist's belief in a malevolent witch presence.
The book deals with parental neglect and emotional instability. The approach is deeply psychological and secular, though it uses the trappings of the supernatural. The resolution is realistic and bittersweet: Jessica accepts responsibility, but her external circumstances (her mother's personality) remain largely unchanged.
A middle-schooler who feels like an outsider and struggles with a 'mean streak' they don't know how to talk about. It is for the child who prefers dark, moody stories over cheerful ones.
Parents should be aware of a scene involving an attempted 'exorcism' of the cat that involves some peril for the animal. Parents may want to be prepared to discuss the impact of parental neglect on a child's emotional well-being, as Jessica's mother's absence and lack of attention contribute to Jessica's feelings of isolation and her subsequent actions. A parent might see their child blaming 'bad luck,' other kids, or 'voices' for their own behavioral choices, or notice a child withdrawing into a fantasy world to cope with loneliness.
Younger readers (10) may take the supernatural elements more literally and find the book genuinely scary. Older readers (13-14) will likely see through Jessica's delusions to the underlying mental health struggles and loneliness.
Unlike many books of its era, it refuses to validate the supernatural as an escape. It is a rare, unflinching look at the 'unlikable' protagonist who is actually just deeply hurting. """
Twelve-year-old Jessica is isolated, her mother is frequently absent, and her only friend has moved away. When she finds a sickly, strange-looking cat she names Worm, she becomes convinced the animal is possessed by an ancient witch named Grendel. Jessica begins committing hurtful acts, from damaging property to social sabotage, claiming the cat is telepathically forcing her to do them. The story follows her descent into this delusion and her eventual, painful realization of her own agency.
