Death is a Vengeance. The McKay Family Saga, #2

Although the war officially ended, the McKay Rangers could not stay in North Carolina, because the Union Army decided to keep the $10, 000 bounty on all bushwhackers. They packed up five large wagons, married their sweethearts, and left on a bright Sunday morning. A few days later, they came up to the Green River-the southern border of North Carolina. The cavalry platoon tasked with border security was led by a familiar lieutenant-one missing his front teeth.
Almost two weeks after the wagons slipped by, he finally realized that the man who had broken his mouth and humiliated him, had slipped through his grasp. Vengeance rose up in his heart like a tidal wave, with the blinding need to find and murder that vicious creature. The Union Army empowered him with a promotion and the authority to pursue the rangers to the gates of hell if necessary.               How does a wagon train of five slow wagons escape the efforts of the mighty Union Army to bring down a terrible and swift vengeance? Then again, would the Union Army survive, if they cornered the deadly mother grizzlies protecting their cubs?
