Having extreme pious and religious convictions (linking absolutely everything she sees to religion and morality), Nessarose is often close-minded and vain, in keeping with Maguire's cynicism throughout the novel towards religion in general. In fact, the extent of her Unionist religious dedication causes even her father, the intensely jealous Frexspar, to worry that she may be "too devout". Unlike in the musical version, however, Nessarose is not infatuated with Boq, the Munchkin boy, or anyone for that matter, and lives a solitary life.
