A mother's love knows no bounds . . . London, 1754. Six years after leaving her illegitimate daughter Clara at London's Foundling Hospital, Bess Bright returns to reclaim the child she has never known. Dreading the worst - that Clara has died in care - the last thing she expects to hear is that her daughter has already been reclaimed - by her. Her life is turned upside down as she tries to find out who has taken her little girl - and why. Less than a mile from Bess' lodgings in the city, in a quiet, gloomy townhouse on the edge of London, a young widow has not left the house in a decade. When her close friend - an ambitious young doctor at the Foundling Hospital - persuades her to hire a nursemaid for her daughter, she is hesitant to welcome someone new into her home and her life. But her past is threatening to catch up with her and tear her carefully constructed world apart.
