In the 1970s, Slone wrote what she felt was an honest account of her forefathers for her grandchildren. She had only a few copies of these accounts printed, never intending for anything to become of it. But after her grandchildren read the works, they enjoyed it so much they passed it around, and the writings built up so much popularity they gave Slone a chance to publish her stories. In 1979, her first book, What My Heart Wants to Tell was published by New Republic. Slone had always been a strong advocate for preserving the Appalachian way of life, disproving many of the myths and stereotypes that follow the culture.
