The best science fiction and fantasy stories from 2018, guest-edited by National Book Award finalist Carmen Maria Machado.

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 spaceships 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 World Fantasy Award finalist Carmen Maria Machado, The Best American Science Fiction and Fantasy 2019 explores the ever-expanding and changing world of SF today.
