When Lucia Zenteno walks into a mountain village in central Mexico, some villagers whisper that her long black hair blocks out the sun, and they are afraid. Others say her brilliant hair outshines the sun. Frightened, they banish Lucia from the village and watch in amazement as their precious river follows her, for it loves her and will not leave her. Never had the villagers imagined that their beautiful river would leave them, no matter what they did and so the whole village sets out to find Lucia and beg for her forgiveness."
