This is the type of book that gives you the chills. I believe almost everyone growing up has been around or been to school with a child who is not quite right. You see them and there's a darkness about them. You want to avoid this person because some primitive part of your brain says, "Run. This person is dangerous." You listen, and you try to stay away and hope that you are wrong, that this person will not do something horrible in the future. When that horrible thing does happen, and others like that person start to copy their work, it all starts to spiral out of control.
