A woman in 15th century West Africa named Ada buries her child and confronts a Portuguese enslaver. A woman in Victorian England named Ada Lovelace, a mathematical genius and computer programming pioneer, tries to hide her affair with Charles Dickens from her husband. A woman named Ada, imprisoned in a concentration camp at Mittelbau-Dora in 1945, will survive one more day in enforced prostitution. Connected by an unknown but sentient spirit, and a bracelet of fertility beads that each Ada encounters at a pivotal moment in her life, these women share a name and a purpose. As their interwoven narratives converge on a modern day Ada, a young Ghanaian woman who finds herself pregnant, alone, in Berlin, searching for a home before her baby arrives, their shared spirit will find a way to help her break the vicious cycle of injustice.
