Black Rainbow by Barbara Michaels (Elizabeth Peters) was an excellent Christmas gift from by Ruby Rose. A black rainbow (rare but real natural phenomenon, which has unusual myths associating it with Diana as Hecate) appears when Megan O'Neill comes into view of the Grayhaven Manor where she has been hired as a governess for Lina, the ward of the owner of the manor, Edmund Mandeville. Edmund's sister, Jane, also observing the black rainbow, sees her coming, and after learning who she is, guides her to her new home. Jane takes care of the manor and the mills, and everyone adores her. Eventually Edmund arrives; he has been away since the war. As a man, he insists on taking over everything, much to Jane's and the entire village's dismay. Whereas she was a kind manager, Edmund wishes to be thought of as nobility, not trade, and make money, not provide for those who work for him. As the man of the manor, he can do that.
Megan, of course, falls for him, but he wants to marry into the nobility, but due to an accidental situation, he overhears his intended tell her brother (who Edmund thought was his best friend) that she is sacrificing herself to Edmund to get them out of debt. Edmund gets rid of the Astleys, but unfortunately not his desire to be nobility. As the story progresses, the reader, Megan, who he does marry, and even Jane learns that rather than a kindly squire, he is a spoiled snob. At various points Megan and Jane rethink parts of their relationship with him and see his former actions in new light. He is hurtful not just to his wife and sister but to the entire community.
As the action proceeds, he becomes worse and worse. Eventually, a woman, undercover, must assume the role of Diana-Hecate in order to put the Mother of God back in her rightful place in the universe--and their community.
It is an intriguing story with clever plot twists. The characters are well-described. One can easily identify with the intelligent Jane or the beautiful Megan. Although written in 1982, it could easily fit in with early women's rights stories--or the Me Too woman's stories of today. But it is realistically told (except for a little Gothic chill to add to the reader's entertainment), and while some male actions are horrific, some of the male characters are fine, kindly, human beings.
I found it immensely entertaining--and so appropriate for shy Ruby Rose.
