Though Waters Roar by Lynn Austin

Harriet Sherwood has always adored her grandmother. But when Harriet decides to follow her footsteps to fight for social justice, she certainly never expected her efforts to land her in jail. Nor did she expect her childhood enemy and notorious school bully, Tommy O'Reilly, to be the arresting officer.

Languishing in a jail cell, Harriet has plenty of time to sift through the memories of the three generations of women who have preceded her. As each story emerges, the strength of her family--and their deep faith in the God of justice and righteousness--brings Harriet to discovery of her own goals and motives for pursuing them.
