Margaret Leroy's Yes, My Darling Daughter
This was one of the books from Oprah's summer reading lists--it's really only a mystery in the most tenuous sense. It centers on a young single mother with a troubled little daughter; eventually, the mother comes to think her child is somebody's reincarnation and turns to an unusual psychology professor for help. From there it becomes much more predictable, but is still a fairly satisfying story. B+.
