Legacy of Love by B.J. Scott

Cautious of marriage, Gwen Lindsay takes a vacation in Scotland while considering Dr. Kyle MacKay’s proposal. But after touring an ancient castle, Gwen accidently steps into a fairy ring on Samhain Eve and awakens in the fourteenth century.
When Kyle MacKay learns that Gwen has disappeared without a trace, he will believe or do anything it takes to get her back—even if it means taking the word of a self-proclaimed witch and going back in time to rescue the woman he loves.
Can Kyle arrive in time to save Gwen from the evil that threatens to destroy her and figure out a way to return to their own century or will they be lost in time forever?
