Kate O'Hearn píše vysoko-fantastické dobrodružstvá so silnými, súcitnými hrdinkami, ktoré milujú dobrodružstvo. Vyrastala ako jediná dievčina medzi chlapcami a všimla si nedostatok ženských postáv v dobrodružných príbehoch. Svoje písanie preto zameriava na vyváženie tejto nerovnováhy a ukazuje, že dievčatá môžu byť rovnako statočné a dobrodružné ako chlapci. Zdôrazňuje, že dobrodružstvá sú pre každého.
