Where the Light Enters by Sara Donati

Light is the sequel to the excellent Gilded Hour featuring physicians/cousins Anna and Sophie Savard in NYC in the 1880s. The story picks up where we left off. Anna, her husband (cop) Jack, and his partner Oscar are trying to find the doctor who is killing women with intentionally botched abortions. Sophie is still recovering from the loss of her husband Cap and trying to start up a way to help other women of color pursue medical careers And their protegee Elise is navigating medical school. It's a
fascinating  look at an important slice of time in the lives of American women.
