Vengeance In The Ashes [EPUB ebook] 

While ending the rule of slavers, thugs, and cannibalistic Night People on the Hawaiian Islands, Ben Raines and his rebel army learn of a new threat to America. A grim spectra from the past-an army of Nazis led by the maniacal Jesus Dieguez Mendoza Hoffman-is marching through South America toward the vulnerable heartland of America. Not content enough to crush America, Hoffman has singled out Ben Raines for a hideous fate. Now, with the famed warrior a prisoner, his life hanging in the balance, only the outnumbered but undefeated Rebels stand in the way of the terrorist trained Death’s Head battalions who are bent on the destruction of the once proud land of liberty and freedom!
