Raised by a cold and distant mother, photographer Paisley Clark has spent her life daydreaming about the father she doesn’t remember. Paisley’s dream turns to reality when a DNA test brings her in contact with the mysterious man. With her financial situation a disaster and her childhood friend James Pressley-Coombes working across the pond in Scotland, Paisley is emboldened to accept her father’s invitation to visit him.

She arrives in the Highlands only to discover that she isn’t Paisley Clark at all but a titled lady, the daughter of a Scottish duke. Despite the warm welcome and the comfort of James’s presence, dangerous undercurrents surround Castle Rannoch, her father’s estate. Overwhelmed, Paisley takes refuge in her camera and James’s steady presence to provide a sense of normalcy in her rags-to-riches transformation. But her once-easy relationship with James is changing, deepening beyond friendship in a surprising twist of events. Before they have time to examine their feelings, Paisley inadvertently captures a shocking image in one of her photographs—a picture worth killing for.
