GHOST of HOMER LUSTA

Confederate soldier Homer Lusta returns to Earth 150 years after the Civil War, the War Between the States, or as Homer would say, the War of Northern Aggression. He remains invisible as he searches for an author to write the "real story" of that war.
Finally Homer selects "Old Bob," materializes himself, and convinces Bob to write the story according to his memory. Homer's adaptation is reasonably accurate and loaded with "Homer humor" as he recalls his endeavors to save the South and protect underage brother, Lack, who illicitly has sneaked, early on, into the battlefield.
The boys are deceived by a corrupt gang of Rebel deserters into thinking the War is over. Unknowingly, they join these renegades, but soon realize they are traitors involved in iniquitous activity.
The boys decide to right this wrong. They search out and inform appropriate Rebel officers. Now having become heroes, the boys return home to accolades few in that war-torn land could ever imagine.
