Treason In The Ashes [EPUB ebook] 

Social decay buckled America and the Great War brought her to her knees. Out of the ashes, two would-be nation states rise. One is built on values of hard work and justice, under the leadership of the outlaw general, Ben Raines. The other would return all power to the federal government and to the very politicians who plunged the USA into destruction once before O Now, the federals have lined up their forces north of the border for a sweep down into the lower forty-eight. Against three powerful divisions, Raines has thrown up nine battalions of outgunned Rebel fighters. But when the shooting begins, a new battle erupts. This time, Raines faces an enemy from behind his own lines as legions of Rebels sell themselves to the opposition-forcing the Southern States to engage in war.
