Dust

Juliette Nichols is the mayor of Silo 18, one of the underground silos that hold what remains of humanity. She has learned that the toxic air outside is not what the founders told everyone it was. Her people respond by digging toward Silo 17, where a survivor called Solo has kept to himself for years.

Elsewhere, in Silo 1, the control silo, the people who built this buried world are watching. They disagree about how to treat silos that have stepped out of line. Whatever they decide puts Juliette's community, and the people closest to her, at risk.

This is the third and final book of the Silo trilogy, after Wool and Shift. It is post-apocalyptic, dystopian science fiction, and it moves between several storylines: Juliette's dig, Solo's isolation and the watchers in the control silo.

All the threads of the series meet here. The puzzle that begins in Wool and the history unfolded in Shift lead to answers about why the silos exist and what lies beyond them. Readers who have followed the trilogy and want a conclusion will find it, and the first two books come first.
