A former feature-story writer and correspondent, Henderson has also written fiction as long as she could remember. Her heritage reflects the contrasts of her Gemini sign. She is a descendent of a coal-miner's daughter and an aviation flight engineer. This dichotomy shows in her writing which crosses genres from historical adventures and westerns to science fiction and fantasy. In the world of romantic fantasy she is the author of two series: Windmaster and the Dragshi Chronicles.
