This omnivorous selection of stories chosen by series editor John Joseph Adams and World Fantasy Award finalist Carmen Maria Machado is a display of the most boundary-pushing, genre-blurring, stylistically singular science fiction and fantasy stories published in the last year. By sending us to alternate universes and chronicling ordinary magic, introducing us to mythical beasts and talking animals, and engaging with a wide spectrum of emotion from tenderness to fear, each of these stories challenge the way we see our place in the cosmos. The Best American Science Fiction and Fantasy 2019 represents a wide range of the most accomplished voices working in science fiction and fantasy, in fiction, today--each story dazzles with ambition, striking prose, and the promise of the other and the unencountered.
