Precious and Grace by Alexander McCall Smith

Alexander McCall Smith's  No. 1 Ladies Detective Agency is a delightful series set in Botswana. If you've watched the HBO series, it's easy to hear Jill Scott's accent through the written words and helps with the pronunciations. Precious and Grace is number 17 in the series and like a re-acquaintance with old friends.

Since the diamond on Meghan Markel's engagement ring came from the diamond mines of Botswana and Prince Harry often visits there, it might evoke new interest in the republic and the No. 1 Ladies Detective Agency is a great introduction to the area.
