Wool introduced the world of the silo.  Shift told the story of its creation.  Dust will describe its downfall.

Juliette, now mayor of Silo 18, doesn’t trust Silo 1, especially its leader, Donald. But in the world of the Silos, there is no black and white—everything is shades of gray. Donald may not be the monster Juliette thinks he is, and may in fact be key to humanity’s continued survival. But can they work together long enough to succeed?

Adam Griffey is living two lives. By day, he teaches literature. At night, he steals it. Adam is a plagiarist, an expert reader with an eye for great works. He prowls simulated worlds perusing virtual texts, looking for the next big thing. And when he finds it, he memorizes it page by page, line by line, word for word. And then he brings it back to his world.

But what happens when these virtual worlds begin to seem more real than his own? What happens when the people within them mean more to him than flesh and blood? What happens when a living thing falls in love with someone who does not actually exist?
