Although none of Stewart's pretrilogy novels have sequels, they do share similar plot ingredients, heroines, values, and sense of place. Each plot contains adventure, danger, and innocent romance. The heroines are spirited, resolute, and selfless. It is their maturity and commitment that make them attractive to the heroes. The biggest variation in the novels occurs in the setting, from the Isle of Skye for Wildfire at Midnight (1956), Corfu for This Rough Magic (1964), Austria for Airs Above the Ground (1965), to France for Nine Coaches Waiting (1958). Although the number of varied settings might tend to make Stewart's novels travelogues, she rises above this temptation, making her settings not only authentic but integral parts of the story.
