- Alternate Character Interpretation: Rachel in the books is presented as an average, if lonely teenager with an interest in metal, who only went off the deep end because of her horrific rape at the hands of Die Every Day's lead singer. However, there were earlier moments in the novel that suggests that she's always had this psychopathic nature to her: her cruel and hypocritical attitude towards Josephine, Rachel's first friend who was always supportive and helpful to her, but Rachel repeatedly lied to and left out in favor of Fern — after Rachel spent the first part of the novel wishing she had a friend that she could receive and give support to. There was also the time where she wrote a poem about hurting her teacher because of her teacher's concerned comments regarding Rachel's darker written works, and her manipulative behavior when said teacher brought her to the principal out of rightful concern that Rachel was threatening her with her aforementioned poem, making them believe it was just a a metaphor about breaking free. But what really clinches this interpretation is the time Rachel actively harmed a rude customer and then laughed madly at the sight of seeing him bleed.
- Designated Villain: Paul is a bit snide and apparently sexist, but does nothing too untoward and even gives Rachel some good advice after her disastrous first show. Rachel gracelessly and very blatantly mocks and derides his band.
- Squick: Rachel's morbid fantasies about bloodplay. She later deals with a heckler by pouncing on him and jamming a finger down her own throat, sicking up her sushi all over the poor prick, right into his eyes and gaping mouth.
- Unintentionally Unsympathetic: According to the reviews on Goodreads, many readers took issue with Rachel.
- Write What You Know: Taylor's experience in The Birthday Massacre clearly informs the touring scenes.
