A sweeping family saga, from the grand homes of Yorkshire and London in the Edwardian era, to the heartbreak of a French nursing station during World War I, and the glamour of American high society in the 1920s.
Lally Leeds is just a baby when wealthy Black Jack Pollock finds her abandoned in a Yorkshire street and decides to raise her alongside his own children. As Lally blossoms into a young woman, the love and loyalty she feels towards her adoptive family bring her both happiness and heartache.
Over time, it is Lally’s strength and devotion which hold the Pollock family together: her dashing brother, Jon; her selfish and self-destructive sister Margaret; and fragile Alice, who must been protected from herself. And the family’s fortunes become entwined with those of another foundling ‒ the mysterious, self-made businessman Brock Weymouth. Lally discovers to her cost that sometimes the most difficult promises to keep are to those we love.
