So all I remember is that the main character was psychic, specifically with the gift of psychometry. I believe she was called Susan, and spent a summer? with an aunt or great-aunt. Two of the objects read were a pocket watch, I think, and a rocking chair, I’m pretty sure.
I know this is vague, but there can’t be that many pre-1990 books featuring psychometry. Perhaps a little TOO vague for google, though, as I’m not having any luck. Any help?
