Promised Valley War is the second book in Ron Fritsch’s four-novel Promised Valley series set in prehistoric times. Blue Sky, the farmer’s son who led the rebellion in the first book, and Wandering Star, the young hunter who became his lover, realize they and their peoples will suffer for the high treason they knowingly commit every moment they spend together. They, along with the other individuals on both sides willing to treat their “eternal” enemies as their equals, nevertheless set the stage for what they’ve feared most: another horrifying war.
