I really can’t remember much more than that there were two guys who were probably grad students; possibly one might have been a professor. They were working on ESP and gave this sad, shy girl a boost to her ego when they saw her in a cafe or cafeteria. They continued to work on her without her knowing it and then I think she was working with them. It was a very hippy-feel-good/save-the-world kind of stories.

I’ve looked for it for years with no luck. Good hunting!
