Today’s readers of science fiction and fantasy have an appetite for stories that address a wide variety of voices, perspectives, and styles. There is an openness to experiment and pushing boundaries, combined with the classic desire to read about space ships and dragons, future technology and ancient magic, and the places where they intersect. Contemporary science fiction and fantasy looks to accomplish the same goal as ever—to illuminate what it means to be human. With a diverse selection of stories chosen by series editor John Joseph Adams and guest editor N. K. Jemisin, The Best American Science Fiction and Fantasy 2018 explores the ever-expanding and changing world of SFF today, with Jemisin bringing her lyrical, endlessly curious point of view to the series’ latest edition.
