I am looking for a book that I read as a child. I grew up in the 80s so it was published before then. It was a somewhat scary and morbid story about a little girl in the woods. I believe something happened with her parents and she was alone. What I most remember is the illustrations were absolutely beautiful. I think the girl’s name was something with an M – Milly, Mildred, Millicent, etc.
The book was so creepy it was almost not for kids.
