Set in New York City during the late 1930's Rules of Civility tells the story of young socialites after the Depression. This story draws heavily on the city and its haunts, painting a picture of a rich and carefree group of friends in their mid-twenties. While I found the book entertaining and enjoyed the reading for the most part, I am not sure how accurately it depicts real lives of the time. I would assume that the wealthier class might not have been so affected by the Depression, but a few of the characters while not presented as upper-class, sure lived untroubled and happy-go-lucky life-styles.
You'd like this book if you love NYC, the post-depression era or people stories (like the Great Gatsby). In general it's a decent read.
