Other works by Mary Gentle contain examples of:
- Doorstopper: Most of Mary Gentle's novels are this. Another writer wrote a 50-word story on Usenet that boils down to "When Mary Gentle writes a shopping list, a spruce tree in Norway shivers."
- Nobody Poops: So, so averted in all her novels.
- Prescience by Analysis: 1610: A Sundial in a Grave revolves around a form of mathematics that can predict future actions, with such precision that a mathematician with no sword-wielding aptitude is capable of winning a fight by predicting it several months in advance and then practicing the exact sequence of moves that will result in victory. One character turns out to be manipulating events because he's foreseen a catastrophe four hundred years in the future that can only be averted if he starts laying the groundwork now.
- Rat King: In Rats and Gargoyles, the titular Rats are ruled by groups of nine of their number with their tails deliberately fused together.
- Sweet Polly Oliver: A driving characteristic of many female characters in her works. Notably Floria/Florian of Ash: A Secret History and Dariole of 1610: A Sundial in a Grave. In the short story "What God Abandoned," Miles claims to be one. S/he's a sex-shifter; it still backfires on them.
