Karen Tintori thought she knew her family tree. Her grandmother Josie had immigrated from Sicily with her parents at the turn of the century. They settled in Detroit, and with Josie's eight siblings, worked to create a home for themselves away from the poverty and servitude of the old country. Their descendants were proud Italian-Americans.

But Josie had a sister that nobody spoke of. Her name was Frances, and at age sixteen, she fell in love with a young barber. Her father wanted her to marry an older don in the neighborhood mafia--a marriage that would give his sons a leg up in the mob. But Frances eloped with her barber. And when she returned a married woman, her father and brothers killed her for it. Her family then erased her from its collective memory. Even 80 years and two generations later, Frances and her death were not spoken of, her name was erased from the family genealogy, her pictures burned, and her memory suppressed.

Unto the Daughters is a historical mystery and family story that unwraps the many layers of family, honor, memory, and fear to find an honor killing in turn of the century Detroit.
