There is a book that I read in Middle School(97-2000) that has been driving me nut to find. I believe it was published in the 70s but can’t be sure. It was mystery/ghost story. I can remember the plot but not the title or author.
The plot centers around a young girl who lives with her father in this big house with bogs nearby. She finds this really old locket which had belong to a young girl who died many years before and whose spirit uses that locket to lure other young girls into the bogs. What happened to the spirits in her life was that she fell in love with a boy who gave her the locket but her father forbade her from being with the boy and she eventually tried to run away or something but got caught in a bog and died. And so her spirit lingers. I believe the protagonist almost dies in a bog but her father saves her. Of course it has my memory of the plot. Perhaps you can help me locate this book.
