"Silo" is based on author Hugh Howey's books of the same name. Seasons 1 & 2 were based on the first book, 'Wool', while Season 3 integrated elements of the prequel book, 'Shift'. Season 4 serves as the definitive adaptation of the third and final book, 'Dust', focusing on the downfall of the silo system.
Showrunner Graham Yost adapted the books with heavy modifications to make the narrative tighter, more personal, and more explosive to fit the episodic television format, while retaining the essence.
