Excitement runs high during presidential election week in 1888. The Woman Suffrage Association plans a demonstration and movement leader Elizabeth Cady Stanton comes to town to rally the troops, one of whom is Quaker midwife Rose Carroll. But the next morning, Rose finds the dead body of the group's local organizer.

Rose can't help wanting to know who committed the murder, and she quickly discovers several people who have motives. The victim had planned to leave her controlling husband, and a promotion had cost her male colleague his job. She'd also recently spurned a fellow suffragist's affections. After Rose's own life is threatened, identifying the killer takes on a personal sense of urgency.

Turning the Tide was a 2019 Agatha Award nominee for Best Historical Novel.
