I am a big reader of southern regional novels, but I stumbled on a Sandra Dallas book called The Persian Pickle Club a couple of years ago and I have read most of Ms. Dallas' books since then. Recently I finished New Mercies and really loved it. Most of the books are set in Denver, or there abouts, and are from the 1920's or 1930's. This book is partly in Denver and partly in Natchez. So it fit the bill for me!
The lead character in New Mercies is slowly recovering from a divorce and the social stigma associated with divorce at that time. She inherits an old plantation house that has gone to ruin, and she travels to Natchez to discover a world completely different from her own and loaded with characters (maybe caricactures would be a better description). It is a fun read and very enjoyable.
Next on my list of Sandra Dallas' books is Tallgrass, I am looking forward to reading it.
