Flames From The Ashes [EPUB ebook] 

The evil Jesus Mendoza Hoffman, descendant of one of the most infamous Nazis of all time, and his fanatical New Army of Liberation pose a dire threat to the new world-and Ben Raines’s rebel forces. With his massive army crushing everything in it’s path, Hoffman is spreading his chilling doctrine of death and destruction from Mexico to the Canadian border. Outnumbered and out-armed, Raines and his men are no match against the black-shirt guerrilla forces. And when Raines is captured, the Nazi exterminator gives the rebels and ultimatum: surrender or Raines dies. Against impossible odds, Raines’s followers must infiltrate Hoffman’s troops and put an end to his brutal reign of terror…before Ben Raines and his dream of freedom are annihilated forever!
