Organizers and activists envision, and try to create, such worlds all the time. This book brings twenty of them together in the first anthology of short stories to explore the connections between radical speculative fiction and movements for social change. The visionary tales of Octavia's Brood span genres—sci-fi, fantasy, horror, magical realism—but all are united by an attempt to experiment with new ways of understanding ourselves, the world around us, and all the selves and worlds that could be. The collection is rounded off with essays by Tananarive Due and Mumia Abu-Jamal, and a foreword by Sheree Renée Thomas.
