Request #596 From Dianne

I read a book in 1975-76 that was sort of light sci-fi about people here who were human but from another planet and had ESP. They were trying to keep us from killing each other by looking outward into space. I remember that the young girl with ESP was able to “teach” her earth friend to use her own ESP by giving her a “pill” that she made from rolling a piece of bread. I loved this book, but this is all I can pull from my memories…
