North Reich

From Conroy's introduction:

North Reich tells what might have happened if Hitler had not so foolishly declared war on the United States.  FDR certainly understood that Germany was the greatest threat, but might have been helpless to do anything about it.  War between the United States and Germany was still considered inevitable, but not in December of 1941.  North Reich is the story of the war that was going to come sooner or later.  However, in this instance, the fighting takes place not in Europe but in North America.
