Showing The Trouble with Witches by Shirley Damsgaard

Ophelia has always considered her psychic abilities an imposition, except for those times she's been able to put her paranormal talents to good use—like when a friend asks her to help find a missing teenager. Unfortunately it means she and Abby, her kindly, canny sorceress granny, will be taking to the road to pursue the vanished girl in the wilds of Minnesota.

The signs are pointing toward the secluded new age research facility of Jason and Juliet Finch, who live with their troubled—and possibly matricidal—thirteen-year-old niece. And a bizarre local murder that follows their arrival—plus the appearance of a mysterious Native American shaman—only emphasize the urgency of Ophelia and Abby's hunt, drawing them into a web of dark secrets and to the last place they'd ever wish to be: a cottage in the woods where true evil quite possibly resides.
