I can't remember where I found the recommendation for Nervous Conditionsby Tsitsi Dangarembga, but I'm glad I did. The novel is set in Rhodesia (colonial Zimbabwe) with Tambu as the narrator.
The beginning of the book was a bit slow and formulaic- a young girl who wants to go to school but is stopped because of the cultural prejudices of her father and older brother. But once Tambu is able to leave home to go to school, the story picks up and is quite good.
could have told it and It's not really Tambu's story here; in many ways it's more her cousin Nyasha's story and Nyasha's descent into mental illness. Tambu is able to tell Nyasha's tale in a different way than Nyasha and Tambu is an effective narrator.
