Tumbling Blocks is number thirteen in the Benni Harper series written by Earlene Fowler. Each of these books have quilt pattern titles and are located in a small California town. In Tumbling Blocks, Benni Harper investigates a mystery surrounding the socialite group of women in the 49 Club. These are lovely cozy mysteries with a western flair and California backdrop and a grandmother, Dove, we would all love to have in our family.
