What is the author's style in Bloodchild by Octavia E. Butler?

The stylistic features that shape the story, Bloodchild, must be understood in terms of the story's genre. As early as the second sentence of Bloodchild, "T'Gatoi's sister had given us two sterile eggs". Most readers will recognize that it belongs to the genre of science fiction. Butler's emphasis on character and development of the plot around psychological conflict, however, are characteristics that are not typical of the genre, which often relies on conventions associated with the genre, such as space travel and high technology, as the driving force behind the narrative.
