Is it literary if it evokes a time and places that are ordinary, at least to current middle class Americans? It is definitely not genre fiction. The first book is a light romantic comedy for the most part. The second book is a tragic family drama, but not presented in the melodramatic fashion, and the third book takes on the flavor of American politics without taking a position. The entire point, really, is to show how the same people can be different in different circumstances and contexts. An entirely literary idea, I would say, but well integrated into the strong plot in each book. Does that make it unliterary?. I also believe that the author should not get in the way of the story just to show off her language skills. Does that make it unliterary? I leave that to you to decide.
