Halfbreed, ugly, barely human in the eyes of those around him. His Medicine-Woman mother, Cursed, banished for the sin of defending her patient/adoptive father against the abuses of the new leader. She was told to find her own people, her own mate. But the boy has two peoples. Half Cro-Magnon, can he belong in either world? He thinks differently than either of his parents. What becomes of him? The author, an inventor and engineer, describes how cold and hunger force these primitive people, with only rocks and wits, to find new ways to hunt and thrive. Like most innovation; motivation, a different way of thinking, plus a coincidental hint, point the way to survival. But the most profound inventions come from a mere girl, the boy's future mate. Through a series of accidental discoveries, Neanderthal life goes from precarious to predictable. But their success could be their undoing. Conflict looms with the Cro-Magnon, led by the boy's grandfather. Who will control the herds they both depend on?
