[1] The main character of the series is an orphan named Catherine "Cat" Royal.
The main themes are slavery and equality between people from all races and social classes.
Themes shown throughout the series include acceptance of different ethnic categories, and expressing the belief that it is not what one likes or social class that matters, but rather, personality.
The theme of making one's way through adolescence could also be considered an aspect of the series, as the protagonist struggles to find work, and a home where she can be accepted for who she is and not be pressured into marriage and other issues faced by most young women during the time period in which the books are set.
