I can't remember much about the story other than the beginning, where a guy is cut off on the highway towards this college and flashes a sign on the trucker's field of view, I believe using his mind. The entrance/turnoff to the school was also hidden somehow I think but I am not 100% on that. It's probably been ten years since I read it, but it's one of those things that pop into my head on occasion.
Thanks in advance, I know it's not much to go on.
