Description

Delve further into world of Silo, the acclaimed Apple Original series based on Hugh Howey’s New York Times-bestselling trilogy of the same name.

Silo is the story of the last 10,000 people on Earth, living in a mile-deep home that protects them from the toxic and deadly world outside. No one knows — or remembers — when or why the silo was built, and those who have tried to dig for the truth have faced fatal consequences.

Adapted from a handwritten journal, this is the first-ever account of Silo 18’s history. Its author, Robert Sims, served as head of Judicial Security under Mayor Bernard Holland and was responsible for securing red-level relics that some feared could incite unrest within the community. Sims held this position when Juliette Nichols, an engineer (or “Mechanical”) from the lowest levels of the silo, returned after going outside and disappearing over a hill.

Unbeknownst to anyone, including his wife Camille — who eventually took over as Mayor — Sims kept a record of his investigation into Relic #1175, a child’s toy with mysterious connections to Juliette and her murdered co-worker. Sims’ candid and illegal account contains many explosive revelations about the silo’s history and leadership.

Silo stars Rebecca Ferguson as Juliette Nichols, Tim Robbins as Mayor Bernard Holland, and Common as Robert Sims. Now streaming on Apple TV.

  • Too many inconsistencies

    This book does not mirror things that we know to be true from the show. It gets several small factual things wrong, and reading these inconsistencies continually took me out of the story. Not enjoyable and it did not in any way help my understanding of the show or add to my understanding of the current plot lines.
