The Day the Earth Rose Up (Paperback)
When seven Lakota sisters venture deep into the forest to gather chokecherries, they are surprised and chased by a giant bear. As they huddle together on a rock ledge and pray for help, the earth rises up, taking them out of reach of the bear. A great eagle rescues the Seven Sisters by taking them to the Star Nation, where they become the Pleiades star formation we see in the night sky.
