Growing up in the orphanage, Heather Blackstone had been taught the art of lace-making. Now a young woman, she earns her living in a Nottingham factory. But legends of her true ancestry haunt her dreams. When a gypsy fortune-teller predicts a journey, Heather's destiny becomes clear: she must find a way to reclaim her family fortune and the castle that bears her name.

Heather's quest brings her to the looming castle occupied by Sir Byron Worthington. Braving his strange, menacing household and vowing to find the lost document that will prove her claim, Heather accepts his offer of employment, only to discover that she is being watched and followed. As the danger escalates, Heather knows she must choose to give up her search or risk her life to become mistress of Blackstone Castle.
