Boká is still a boy, but the laws of the clan must be obeyed. And, before migrating south for the winter, it is time for the great stag hunt. So Bo, the young apprentice to a shaman, will be called to take up his spear and take part in the tasks befitting warriors and hunters. His small clan will have t confront many challenges: few men, a lack of food, the change in the climate of the areas where they live; and also jealousy, betrayal and fights against neighbouring tribes. Although they don’t realise it, the world will never be the same again. Even so, the spirits still inhabit the forest and their souls need to be able to connect with them. And Bo knows how to do something almost none of the others can: paint. Set in the Iberian peninsular during the Upper Paleolithic Age, the author uses great imagination to explore the dawn of human civilization and the birth of art.
