Cosmogramma (2018)

"In his exquisite first collection of speculative fiction, Courttia Newland envisages an alternate future as lived by the African diaspora. Kill parties roam the streets of a post-apocalyptic world; a matriarchal race of mer creatures depends on interbreeding with mortals to survive; mysterious seeds appear in cities across the world, growing into the likeness of people in their vicinity. Through transfigured bodies and impossible encounters, Newland brings a sharp, fresh eye to age-old themes of the human capacity for greed, ambition, and self-destruction, but ultimately of our strength and resilience"--Inside jacket.
