So, there is a book I’m trying to find. I’m afraid that I don’t have much to go on. All I remember is that it was a thriller plot, and that the protagonist girl was missing one finger. It was something she was embarassed about, and she was a loner at school, not wanting anyone to know unless they were a good friend or family.
At one point during a thunderstorm outside, she looks out her bedroom window and thinks there is somebody spying on her next to a tree.
This book would have probably been printed in the late 80s, possibly 1990 or so. I read it in my elementary school class around ’91.
