- Adaptation Displacement: Averted. Many people do not know about the stage version, even though it ran for along time and got a thumbs up from the author.
- Complete Monster: Possibly Jude. Arguably a much more developed example than normal for this trope, as his moral descent is detailed and believable, and it is shown that he does still have some affection for certain people, though it does little to stop his increasingly evil acts. While he remains a Well-Intentioned Extremist for most of his life, few could argue that his deliberately convincing his teenaged niece to become a suicide bomber is excusable by any standards.
- Moral Event Horizon: Jude's murder of Kara. Possibly he himself considers it to be this, as he is notably more heartless afterwards, and much as he suppresses his conscience, it's clear that he never forgives himself for it.
- Narm Charm: When Jude tells Cara that nought women often try to look like Cross women. He has a point, but then he tells her that they can buy panties which are padded so they can have more curvy hips, it just becomes funny. But still sad.
- Tear Jerker:
- Callum's hanging
- Much of Callie Rose's childhood counts as this, to the point that she is talked into becoming a suicide bomber while still a child. It is chillingly believable that she could be driven to this by the hell of her upbringing, and the manipulations of her uncle.
- What Do You Mean, It's Not for Kids??: The series is targeted at Young ADULTS, and should not be read by any one under 13. Still does not stop parents buying them for a 10 year old then complaining.
