Paradise: Book 2 of the Granny Woman Tales in Bloomington, MN

Herbalist healer Sephronia Hill returns home to Dark Hollow, Tennessee, for the funeral and burial of her sister Agnesia. But is the ever-prickly Agnesia completely gone?
From beyond the grave, Agnesia invisibly -- and violently -- protests her sister's life choices especially the presence of Sephie's companion Floyd Whiteman.
Or so it seems.
IS it Agnesia? Or is it something far darker and more malevolent?
