India 1935: Amelia Collins, a missionary’s daughter, left destitute by the death of her parents, leaves their home in the Himalayan foothills to find work in Darjeeling. There she meets District Officer Reginald Holden, a powerful older man, who spirits her away from poverty and prejudice to start a new life as his wife in Ganpur. Amelia soon forms a bond with Reginald’s young son, Arthur, and resumes missionary work in the villages around Ganpur. There, she discovers a pavilion on a lake where the wives of maharajahs once bathed, now abandoned and cloaked in mystery. When the Indian independence movement flares in Ganpur and Reginald struggles to contain it, Amelia’s world begins to fall apart as she uncovers the shattering truths he has been keeping from her.

Sorting through long-hidden papers, she begins to unearth Amelia’s secrets from her years in British India. But Kate is harbouring a secret of her own – a devastating betrayal from that last summer of the war. She has lived in the shadow of that day ever since, but Kate is convinced that unlocking the truth about Amelia’s Indian past will hold the key to her own future…
