The Giver of Stars

Alice meets and marries Bennett Van Cleve, and before you know it, she is off to live in small-town Kentucky. She hasn't much to do there, and when women in the community are asked to help with a project to establish the Packhorse Librarians of Kentucky, Alice volunteers. She soon finds good friends among the librarians, a comfort because her husband is distant and unavailable. Her best friend is Margery, an unconventional woman, who refuses to marry despite the appeal of her boyfriend of ten years.

There's lots more to the story, with mine problems and flooding problems and even a murder.

My favorite part, of course, was the storyline about the Packhorse Librarians.
