Will you help me think of a name of an author?

This lady was described as one of Stephen Kings favorites in his book on how to write a book.

I think her first name started with an R.

The stuff I read from her were short stories. Beautiful verbage lovely contstruction of sentences and her stories evoked an emotional response.

This author is not new. I found her in the stacks at the library with an old and dusty cover.

The last three details are guesses as I read the books some time ago.
