The next book in Howey’s series, Shift, is comprised of three novellas, “Legacy,” “Order,” and “Pact,” that are prequels to the story of Wool, so it’s unclear whether or not a second season of Silo would be a straight adaptation. This shocks Deputy Marnes (Will Patton) and Mayor Jahns (Geraldine James), but nevertheless sets them off on a journey to the depths of the silo that Juliette resides – the same journey that “Proper Gauge” tells the story of. At the end of episode two, it’s revealed that Holston (David Oyelowo) named Juliette (Rebecca Ferguson) to be his successor as sheriff, despite the fact that the two barely know each other. Wool seems to be the primary source material for the first season of Silo, as the first two episodes of the series show us Holston’s story and introduce us to silo mechanic Juliette, who becomes a major character in the other four novellas.

If you’re already intrigued by the premise of this series from the first two episodes and can’t wait to learn more about his world, then you’re in luck – Silo is based on a series of books by Hugh Howey that already has three novels released, and a fourth on the way. The sensors that show the barren wasteland on the other side of the airlock do a pretty good job of deterring even the more curious citizens of the silo, but there are still those who question whether what they see outside is reality.

People are permitted to explore the outside if they demand it, but there are no take-backs once the request has been made. The silo’s inhabitants don’t know how the world became toxic or who built the silo that became their salvation, nor are they allowed to ask questions about it. The Apple TV+ series Silo is set in a post-apocalyptic world where humanity has been forced into an underground silo because the outside world has become toxic.
