Eager to escape a disastrous relationship, archaeologist, Ellie Harper, jumps at the chance to travel to the remote Scottish Highlands, and excavate the ruins of Castle MacKinnon. However, no matter where she goes, the shadow of her ex follows her, promising she will never be free of her painful past.
But, when a mysterious stranger turns up half-dead on her doorstep in the middle of a violent storm, Ellie is thrust into the realm of ancient secrets and impossible magic that challenges everything she holds dear.
Faced with a heartbreaking decision, Ellie must put her emotions and logic aside to help Laird Ewan MacKinnon find a way home to the thirteenth century - if one exists. What she doesn't expect is to journey to a past more astounding than history, find a love more precious than ancient treasure, and survive the deadly wrath of an evil man's revenge.
