I have been searching for so long for a certain series of novels. The only things I remember about the series is that the covers had an eye and a house partly submerged under water. It was a series of 6 books, each with a different colour. The plot concerns a woman who mysteriously appears after a flood in a southern town ruled by the matriarch of a family. The mysterious woman ends up marrying this matriarch's son and then the fun begins: disappearances and good fortune to those who deserve it.
If this sounds at all familiar, please help.
