Joan MacKimmie is on her way to Paris to take up her vocation as a nun. Yet her decision is less a matter of faith than fear, for Joan is plagued by mysterious voices that speak of the future, and by visions that mark those about to die. The sanctuary of the nunnery promises respite from these unwanted visitations, or so she prays. Her chaperone is Michael Murray, a young widower who, though he still mourns the death of his wife, finds himself powerfully drawn to his charge. But when the time-traveling Comte St. Germain learns of Joan's presence in Paris, and of her link to Claire Fraser--La Dame Blanche--Murray is drawn into a battle whose stakes are not merely the life but the very soul of the Scotswoman who, without even trying, has won his heart.
