From the Sunday Times bestselling author of The Familiars

Two women, bound by a child, and a secret that will change everything . . .

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, she is astonished when she is told she has already claimed 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's 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.

From the bestselling author of The Familiars comes this captivating story of mothers and daughters, class and power, and love against the greatest of odds . . .
