Request #592 From Sarah

I have a vague memory of a YA book I loved that follows multiple generations of Scottish women, starting in maybe the 1700s and ending in the 20th century. All the women in this family have magic of some kind, and red hair. I think the cover is an illustration of a woman looking at the ruins of a castle. I know this is like every stereotype of a book set in Scotland, but figured it’s worth a shot!
