Carlota Moreau is one of the two protagonists of the novel, and also the titular character. About half of the novel is narrated from her point of view, providing access to her thoughts and feelings. In 1877, when most of the action of the plot takes place, Carlota is 20 years old. She is a beautiful, young woman, who is often described by the male characters in ways that evoke sensuality. Montgomery describes her skin as “healthily bronzed, the hair tumbling in a thick wave to her waist was jet-black; the honey was in her eyes” (59). Carlota is simultaneously independent and free-spirited, and sheltered and coddled. Her father’s wealth and power mean that she has always been sheltered and cared for, but she has also been free to live in unconventional ways within the boundaries of her estate: “[T]he doctor’s daughter could do as she pleased because it was Yaxaktun” (57). Carlota is well-educated and given a great deal of intellectual freedom, but she is also naive and idealistic, especially in her fantasies about romantic love—qualities that allow the men in her life to believe she can be easily manipulated and controlled.

Carlota experiences significant character growth and development as the plot unfolds, especially as she learns new information about her true identity and power.
