The discovery of two old photographs, one of a large house, the other of three girls in Edwardian dress, puzzles 20-year-old Lucy Armitage and starts her off on a quest with antique dealer Ben Manton. Although she is sure it can have nothing to do with her, one of the girls in the photograph looks uncannily like Lucy herself. Together they visit Rookhurst Hall, which Ben has recognised as the house in the picture, but what they find only deepens the mystery. When Ben locates Lucy's lost grandmother, a story of love and heartache unfolds. It is a story that could change the course of Lucy's life . .
