Once a Long Time Ago

Those living in the wilderness of what was left of the American West, had no idea that once, a long time ago, life there was so much different. Something terrible had happened. And now, only tribes of people, living as our primitive ancestors did, were all that was left. But things were about to change for one tribe when one of their members discovered a time capsule that must have been left by someone long ago. It contained the resources necessary to teach them how to read, and books that told them about a world they never knew existed. One of the tribe, a young woman, with the help of someone from this world, leads her tribe on a journey to find their place in what is far more complex and challenging than they could ever have imagined.
