This quick-reading children's book (about 4-5th grade reading level)is set in the period of Cro-Magnon man during the European Ice Age. Two tribes meet (through the young hero, Dar)and exchange new inventions - flint for making fire, and spear throwers made from ivory. There is conflict between the older and younger generations, just as there is in modern families.
Adequate, not great.
