At the center of the novel is a woman named Tig, a grandmother who chooses to leave her family for a year to join a walk across America in the spirit of her activist youth. But as she physically traverses the continent in the name of community, she finds herself negotiating the more complicated territory of familial allegiance. In a web of correspondence, her daughters, husband, and grandchildren speak to and through each other, recasting and reinterpreting events back home, revealing themselves in the telling. Through their stories, Greenberg illuminates the monumental landscape of family, her words exploring that which can be communicated to those we love and that which love unalterably obscures.
