Bones by the Forest Road - The Viking Witch Cozy Mysteries, #8

Ingrid Torfa finds herself on the road with two of her closest friends, Kara and Nilda Mikkelsen. Not a hiking and camping trip for pleasure, but a mission of the utmost importance. The Thors disappeared months ago along with their mentor Frór. On a mission to protect Villmark, the village on the North Shore of Lake Superior where they still live like Vikings, hidden from the modern world, the Thors traveled far into the north of this magical realm.
Dangers lurk there, things not seen in the modern world in centuries, if ever. Now Ingrid and her friends are desperate to find out what happened to the Thors. Strange folk haunt the northern roads. The three seek an old ally, but find instead another murder, one with ties to Villmark itself. And if Ingrid doesn't find the killer first, all of Villmark stands in jeopardy.
