I had promised to write more about this story and so now is my chance!

"They met in college, got married right after graduation, and then the war broke out," Henry continued. "The government needed mechanics and mathematicians more than they needed teachers. Dad ended up being shipped wherever he was needed to train people. Mom ended up working with an aeronautical design team in Newport News."
Aha! It makes sense that Henry's mother would work with the same group as Dr. Katherine Johnson! Excellent nod to
Hidden Figures.
Lois was quiet for a long moment, no doubt considering how much more she could get Henry to reveal about the inner workings of the Truman Towns. There wasn't any more he could tell her. He had left Eureka for college thirty-six years before and had only gone back for family visits. He hadn't gone back at all after his parents died – first Dad of a heart attack and Mom a few weeks later of a broken heart. He had repeatedly declined invitations from Global Dynamics to head up one or more of their projects. He had turned down all their offers so far but he knew it was only a matter of time before they found something to lure him into their grasp. Only time would tell him what that something was.
Excellent lead-in to the series itself! Thanks so much for a lovely read.
