"Vows" is a compelling story of one family's unshakable faith that to be called is to serve, however high the cost may be. Peter Manseau's riveting evocation of his parents' parallel childhoods, their similar callings, their experiences in the seminary and convent, and how they met while tending to the homeless of Roxbury, Massachusetts, during the riot-prone 1960s is a page-turning meditation on the effect that love can have on profound faith.
