Mountain Echoes (The Walker Papers)

You can never go home again Joanne Walker has survived an encounter with the
Master at great personal cost, but now her father is missing - stolen from the timeline.
She must finally return to North Carolina to find him - and to meet Aidan, the son she
left behind long ago. That would be enough for any shaman to face, but Joanne's
beloved Appalachians are being torn apart by an evil reaching forward from the distant
past. Anything that gets in its way becomes tainted - or worse. And Aidan has gotten in
the way. Only by calling on every aspect of her shamanic powers can Joanne pull the past
apart and weave a better future. It will take everything she has - and more. Unless she
can turn back time...
