Final answer:
Esther is most likely a romance or mystery genre novel, given the absence of elements typical of fantasy and science fiction genres.
Step-by-step explanation:
Esther could potentially belong to either the romance or mystery genres when considering the conventions of literary fiction and genre classification. Romance novels, like those of Jane Austen, emphasize the development of relationships and love stories. Mystery tales, often including elements of the gothic such as seen in works by Edgar Allan Poe and Mary Shelley, might feature monsters, occult forces, and magic in dark, supernatural settings. Given that genres such as fantasy and science fiction typically involve elements that are not present in Esther, such as magic in fantastical worlds or advanced technology and space exploration, respectively, it is less likely that Esther belongs to these genres.
