RINGSTONES by Sarban. The tagline on the cover says “A Tale of Dark and Mordant Horror.” I read this years ago but honestly don’t remember much about the darkness or the mordancy. What I do remember is that the cover is one of my favorites from this era Ballantine, gorgeously painted with an eerie, moody color palette that creates a very chilly sense of some-thing that the story itself probably didn’t quite deliver.
