Mystery: The No. 1 Ladies' Detective Agency by Alexander McCall Smith. There are 14 books in this series so far and there isn't a disappointing one among them. Precious (Mma) Ramotswe is indeed a remarkable creation.
One of the best books I've read in a long time. A story about a family and their struggle living through the Depression. The author's descriptions and character development make you feel as if you have gone back in time.
