Destiny in the Ashes [EPUB ebook] 

Ben Raines and his army won a war on two fronts, bringing law, peace, and prosperity to the Southern United States of America. But SUSA’s northern neighbor and erstwhile enemy, the United States, is in chaos. And when a ferocious invader attacks the soft and crippled nation, Raines has no choice but to act! Courageous warlord Abdullah El Farrar has risen up from the humiliated regions of the oil-rich Near East–unleashing a stunning attack against the once proud northern United States. No one in the Southern States is surprised that USA cannot defend its own land. But with northern citizens defecting by the thousands to El Farrar’s forces, Raines can see the handwriting on the wall: his brave armies must go to war–to save their enemy from itself.
