Billie, whose obsessive devotion to the Thorntons' children's clothing empire has kept her from finding love. It is also the story of Fanny's search for her own roots. . . and her relationship with Marcus Reed, the wealthy but mysterious businessman who promises her a passion she has been denied for too long.
