Short stories from the African immigrant experience

Collections of short stories can be hard to gauge because the quality can vary even if the stories are all by the same author. This first impression includes the first two stories in Send Her Back and I'm eager to read the rest. Just reading the two stories, you can get a sense that there is a rich diaspora in the Zimbabwean/African immigrant experience and I'd love to see more such books and authors in the mainstream. For me, short stories can sometimes feel a bit unsatisfying because of the length (it's hard to fully develop story arcs or characters), but I appreciate that these stories give you something to ponder even after you finish the story.
