Stone Hearted Lady of Lufigendas Hearmbeorg

A short book about a strange hill in a loanly valley. The hill would be unremarkable save only that somtimes by night the ghost of a girl is seen running up the hillside. Sometimes she is alone, at other times the ghost of a man follows. But who are they? And what is the reason for these unquiet souls to come to be in such a place?
