Ian Blake, Lord Dumbarton, is either being haunted or going mad. But when his aged, spinster cousin arrives at his ancestral home, Dubhmara, with a young and achingly beautiful companion in tow, he knows what she's about—matchmaking. No matter how tempting he finds the lovely and seemingly delicate Hyacinth Collier, the strange circumstances surrounding the disappearance and presumed death of his first wife have left him in a state of limbo. He is not free to marry, and she is not the sort to be a mistress. But then the darkness that surrounds him, that torments him nightly, sets its sights on Hyacinth, and Ian realizes he will face any foe, no matter how terrifying, to save the woman he loves.
