Nnedi Okorafor's Who Fears Death was optioned by George R. R. Martin for an HBO series, so you can bet the world in the novel is detailed and intense. Instead of following a Western city or elite scientists, however, Okorafor focuses on Onyesonwu, a woman in a segregated, post-apocalyptic fantasy world who is trying to protect her own developing powers from a mysterious enemy — while just trying to survive in this ravaged version of Africa.
