I was very interested in the Creole culture and wanted to learn more about it. I got hooked on a historical series by Barbara Hambly about a man named Benjamin January who solves mysteries in Creole New Orleans. These books have made the rounds at my job and are quite a hit.
The first book is called A Free Man Of Color.
Anne Rice also wrote a book about the Creole culture in New Orleans called The Feast of All Saints.
