Won't Wave My White Flag - Marvel

Antonia "Tonia" Stark was born and raised in a dystopian America dominated by Nazi Germany and Imperial Japan following the World War II defeat of the Allied powers until a deadly secret forces her to use the Tesseract in a last-ditch attempt to escape.

Anthony "Tony" Stark is finally starting to move on from the aftermath of the 'uncivil' war when FRIDAY alerts him that she's detected traces of Tesseract-energy in New York, but what he finds isn't the beginning of an alien invasion, no; it's something much, much more intriguing.

A chance for true understanding and acceptance is a gift beyond either Tonia or Tony's imaginings, one that leads them down a path neither expected even as the danger of an impending invasion, the potential return of the Rogues and the dark shadow of Tonia's universe haunt their footsteps, threatening their new, fragile hope for a chance at real happiness.
