From the internationally bestselling author of The Gilded Hour comes Sara Donati's enthralling epic about two trailblazing female doctors in nineteenth-century New York.

Obstetrician Dr. Sophie Savard returns home to the achingly familiar rhythms of Manhattan in the early spring of 1884 to rebuild her life after the death of her husband. With the help of Dr. Anna Savard, her dearest friend, cousin, and fellow physician she plans to continue her work aiding the disadvantaged women society would rather forget.

As Sophie sets out to construct a new life for herself, Anna's husband, Detective Sergeant Jack Mezzanotte calls on them both to consult on two new cases: the wife of a prominent banker has disappeared into thin air, and the corpse of a young woman is found with baffling wounds that suggest a killer is on the loose. In New York it seems that the advancement of women has brought out the worst in some men. Unable to ignore the plight of New York's less fortunate, these intrepid cousins draw on all resources to protect their patients.
