Mary is an orphaned, homeless, African American child, abandoned by the rest of her family and left to care for her younger brother. She becomes a "roadwalker," a nomad who wanders across the rural south and quickly learns to rely on herself to survive.

When she grows up to become a successful artist and a designer, she has a daughter of her own, Nanda, and she's determined to hold her child close. But when Nanda is accepted into an elite school on the East Coast, integrating the all-white Catholic girls' academy, Mary finds she can't keep some of the world's cruel realities at bay forever.
