On a hot August day in the heart of tobacco country, Harvey and Ox are driving County Route 1012, smashing mailboxes with a baseball bat. With one fateful swing, a bomb intended for the Olive family blows the boys to pieces, scattering their remains in the ditches and on both sides of the dotted yellow line. Behind the explosion lies a story of young love, family feuds, and the cultural clash of a changing South -- a place where Mexican migrant workers are transforming the face of North Carolina, one town at a time. In Cottesville, these migrant workers find an unlikely champion in 20-year-old Mike Olive, a rich farmer's boy who has returned home from college bent on social justice. Mike knows he can expect trouble from his family, his friends, and his old rival Harvey; what he does not expect to find is Hermelinda Salmeron, the extraordinary daughter of one of his father's workers. With explosive energy, Luck lays bare the strange collision of fathers and sons, lovers and rivals, Mexico and the American South, the future and the past.
