Well I had been rereading a book called Settling Accounts: The Grapple set in a universe were the South won the civil war and both became two separate nations. Both fought in several wars which the south won, then in WW1 The US army after adopting their army style from the Germans (who are their allies in WW1 and WW2, and still are a Kingdom and ruled by the Kaiser.) Now the South led by Jake Featherston attack the North to end it once in for all.
It is a series a book were it starts
in Settling Accounts: Return Engagement, then Drive to the East, The Grapple, and then In the Death.
I am currently in the Third Book and it is pretty interesting.
First Sketch is An American Tank crew fighting the Confederates.
Second is the Dictator Jake Featherston leader of the Fascist "Freedom Party."
Third is Socialist US Congressman Flora Blackford.
For more info here it is [link]
But I suggest that you all read the book it is a really interesting book series.
