ECO: The Year's Best Speculative Ecofiction, the first-ever annual showcase of the best nature-based science fiction and fantasy published around the world, presents a new collection of short stories by some of the finest writers in the field. Featuring both established names and rising stars, this series explores humanity's deep relationships with other species and our communal fears, grief, and passion as we try to protect our natural world-- all told through the lens of the fantastic. Crossing over with a range of other subgenres, from literary science fiction to fantasy and magical realism, each anthology forms a unique snapshot of how some of the most imaginative writers on the planet are engaging with this extraordinary time in Earth's natural history. The finalists featured in ECO25 were selected by a team of passionate ecofiction judges who read hundreds of nominations from anthologies, magazines and journals around the world to find only the very best. This second edition of the series showcases some of the most vibrant, emotionally impactful and imaginative stories published about our living planet last year.
