Black RainboweBook - 1983
Megan O'Neill sees it hanging in the sky above the towers of Grayhaven Manor -- a beautiful yet sinister black rainbow, a warning to the estate's new governess to stay away. Yet the warmth and kindness of the Mandeville family banish her fears -- and her hypnotic obsession for her handsome, mysterious new employer blinds her to the darkness within. But desire always has its price. And the shocking secrets enclosed in Grayhaven's walls threaten to pull Megan into the terrifying shadows, never to emerge again.
