Parable of the Talents (1998) (the sequel to Parable of the Sower) tells the story of how, as the U.S. continues to fall apart, the protagonist's community is attacked and taken over by a bloc of religious fanatics who inflict brutal atrocities. The novel is a harsh indictment of religious fundamentalism, and has been compared in that respect to Margaret Atwood's The Handmaid's Tale.
Butler had planned to write a third Parable novel, tentatively titled Parable of the Trickster, which would have focused on the community's struggle to survive on a new planet. She began this novel after finishing Parable of the Talents, and mentioned her work on it in a number of interviews, but at some point encountered a writer's block. She eventually shifted her creative attention, resulting in Fledgling, her final novel. The various false starts for the novel can now be found among Butler's papers at the Huntington Library, as described in an article at the Los Angeles Review of Books.
