Futures I couldn't find on the shelf

I grew up reading whatever SF I could find. Clarke, Asimov, some Heinlein that I bounced off hard. Every story was set in a future where the African continent appeared occasionally as context, never as centre. Cities on the moon, generation ships, post-scarcity civilisations, and somewhere off-screen: the rest of the world. I'm an accountant in Accra. I balance ledgers, I close books, I am quite good at finding the number that shouldn't be there. I started writing Afrofuturist fiction because the future I want to live in doesn't exist in print yet and I had some ideas about what it might look like. My current project is a novella set in 2140 Accra, built around the transformation of the Abossey Okai spare parts market into a hub for fabricating parts for orbital construction projects. The economics interested me first: how does informal trade infrastructure scale to interplanetary supply chains? The characters arrived after. My protagonist sources components for a Ghanaian-owned space station. The logistical problems she faces are not that different from the ones she'd face today. I want the future to feel earned, not imported. That's the whole project, I think.
