(From the publisher):
By the light of a gilded moon, a mysterious black rainbow framed the huddled towers of Grayhaven Manor, a vision of ominous beauty that seemed to warn Megan O'Neill of a darkness within. As the estate's new governess, her apprehensions were banished by the welcome of the Mandeville family. But Megan's growing obsession for her handsome employer blinds her to the terrifying truth of Grayhaven.
