Sarah Munro is a myth chaser.
The Laird of Strathordell castle employs Sarah to find the origins of the Scarf, a scrap of fabric which dates from the twelfth century when the family castle was built, because he has received a challenge, not only to his ownership of the Scarf, but also to the castle and to his position as Laird.
The challenge comes from Gregor MacQueen, a dynamic, self-confident land-owner, who lives in a grand manor house at the other end of the island.
Sarah, with demons of her own, has several disturbing encounters during her investigations with the faeries of the Unseelie Court, who wish her harm. Her logical viewpoint on life is shaken as she tries to convince herself that she imagines the episodes.
As she gets closer to the truth, she finds love but events take a dangerous turn and she must fight a dark menace which threatens them all.
