The Price of Salt by Patricia Highsmith

I'm reading The Price of Salt by Patricia Highsmith. The book, written in 1952, is elegant. This is an example of lesbian literature and gay fiction that I think illustrates the potential power of narrative. It is a compelling story of love up against a hetronormative culture. This book was recently made into the movie Carol. It took awhile, but love prevailed! I'd like to see poly novels written like this. I'd like to see examples of poly fiction that illustrate the potential power of narrative to tell compelling stories of love up against a mononormative culture.
