July 2085. Stephanie Nova and Justin Kim are 25, Jeremiah Day is 28. Lucy Harris is 19, Violet Deppiesse is 55.

In this full house, Stephanie's bedroom was one rare place where she and Justin could steal a moment of quiet together. Only a moment, probably, before one of the girls came bursting in or her parents came knocking. They had about an hour once he was home from work on Tuesdays and Thursdays before he had to leave again for guard duty at the road. Each family in the neighborhood took two six-hour shifts each week, and since Justin was the only member of their household that wasn't a child or elderly, pregnant or half-blind or minding a thousand children, it usually fell on him. He didn't mind, though. It was boring most of the time, but their neighborhood was one of the safest places in town because of it.
Then, just as they thought they might mess around for a few minutes before he had to go, Stephanie's phone rang. She didn’t answer it, but they both knew who it was. Since she lived with almost everyone she knew and all of her daycare kids had stopped being dropped off, she didn't get phone calls from that many people anymore.
"He’ll be mad," Justin said.
"Not as long as I call him back before he tries a second time," she said.
"Yeah, well, what is that? Like five minutes from now?"
