Somerset, 1836. Baby Hope is secretly removed from Briargate House because her birth proves Lady Harvey's adultery. Raised by the poor but loving Renton family, she grows up unaware of her true identity and believing their crowded cottage is her only home. When she later enters service with the Harveys, Hope witnesses something dangerous and is forced to leave the people she loves. Alone and destitute, her courage and natural gift for caring for the sick bring her to the attention of a doctor. She trains as a nurse and eventually faces the brutal conditions of the Crimean War, where her strength is tested daily. Yet the secrets surrounding her birth continue to shape her life, drawing her back to England to confront the Harvey family and claim her own future.
