Carla Sue Kelly (born 1947) is a popular and acclaimed writer in the Regency romance genre. She is the author of over forty books and short stories. Her books are what romance readers call "keepers," i.e. books they keep in their private collections, and accordingly they can be hard to find. Renowned for what she calls "dukeless" regencies, her stories often revolve around ordinary people solving their own problems. However, her regencies only reflect a part of her writing interests. She also has a strong interest in the American West, which is reflected in her earliest published works and in her non-fiction. Since 2011, Kelly, who has a Mormon background, has written four historical romance novels that focus on the lives of young Mormon women: Borrowed Light, Enduring Light, My Loving Vigil Keeping, and Safe Passage.
