The Gemma Doyle Trilogy places heavy emphasis on identity and social oppression, often foregrounding themes of female empowerment and outcast status over traditional narrative conflict. There are several instances of modern ideological themes taking precedence over period-appropriate character motivations. Central characters often embody a blend of progressive traits, sometimes at the expense of nuanced flaws or genuine stakes.

Traditional family structures, religious rules, and gender norms are routinely questioned or subverted throughout the trilogy. Masculine figures are sidelined or shown as obstacles, while heroine agency and sisterhood are celebrated. The setting becomes nearly a backdrop for modern discussions around gender and autonomy, rather than a realistic portrayal of Victorian culture.

Dissenting or traditional perspectives are often painted as oppressive or villainous, rarely given nuance or complexity. The dominant worldview aligns closely with contemporary progressive standards regarding gender and authority, with very little internal debate or sincere portrayal of alternatives.
