It is eleven thousand B.C. and the early Native American tribes are battling for the colossal herds of bison that roam the prairie. As the Four Tribes of the mountain people prepare to haul bison meat back to the western peaks, Mira, daughter of the chieftain of the Tolai tribe and her mate Thais, are happily reunited with their pet, Wolf, and his new mate, Dona. Anxious to depart before the Menkala, brutal warriors of the plains, sniff them out, Mira and her young family have no idea just how challenging their trek is about to become. While the Menkala lurk in the shadows and wait for the gods to favor them, a fiery tail blazes through the sky and hits the earth. Certain that it is a sign, the tribe heads toward the point of impact where they find a glowing ember they believe to be a powerful and magical stone sent by the gods. As a new religion is born that threatens to destroy the tribes of the plains, the Four Tribes set out on a perilous journey where Mira will face the greatest trials and adventures of her life. In this continuing tale of adventure, war, and struggles in the North American wilderness, a battle ensues for possession of a magical stone as a young Native American realizes she must kill in order to live.
