Book adaptations are not new, but they’re something people always look forward to. Silo is Apple TV’s science fiction dystopian series set in a post-apocalyptic world. So, what book is Silo based on?

Silo consists of 10 episodes, with Rebecca Ferguson (Dune and Mission Impossible films) starring in the lead role. The story follows a community of survivors living in a silo (a cylindrical tower used for bulk storage).

The people there do not know who built the silo, and why they are underground. They only know that the world outside their sanctuary is death.

There is order in the silo as long as the inhabitants follow the rules and do not say they want to go outside, or else they will go outside. But inhabitants start questioning the world beyond, and one of them seeks to find out the truth.

Sounds like a dystopian science fiction plot. So, what book is Apple TV’s Silo based on? Silo is based on the Silo book series by American author Hugh Howey, with Wool as the first novel in the series.

"If the lies don't kill you, the truth will."

Silo is based on the post-apocalyptic science fiction book series of the same name written by Hugh Howey. Howey self-published Wool in 2011 and intended for it to be a standalone story only.

However, following Wool’s success, Howey wrote more books (Shift and Dust). Wool also has a graphic novel. So, if the Apple TV series becomes a hit, we can expect more seasons to come.

"We do not know when it will be safe to go outside. We only know that day is not today."

As in the book Wool, Silo is set in a post-apocalypse and dystopian future where a community exists in a giant silo hundreds of stories underground.

The story mainly involves characters uncovering the mysteries and secrets surrounding the silo. Apple TV summarizes the Silo series this way:

In a ruined and toxic future, thousands live in a giant silo deep underground. After its sheriff breaks a cardinal rule and residents die mysteriously, engineer Juliette starts to uncover shocking secrets and the truth about the silo.

As in dystopian stories, the characters are in a society where there are many rules and regulations that are “meant to protect” them.

This community is the last 10,000 humans living on the planet Earth, and they’re living in a silo with 144 floors.

Leading the series is Rebecca Ferguson as Juliette, an engineer looking for answers after someone she was close with ends up getting murdered. Mysterious things start happening, and Juliette wants to find out what’s being kept from them.

“Juliette is constantly seeking the truth. The truth about the bigger question of why they’re there… But Juliette finding out the truth creates a domino effect into huge chaos,” said actress Rebecca Ferguson.

Inhabitants of the silo start questioning what’s outside the silo. They start thinking that maybe what they see is not what’s actually out there. Thus, there’s a threat to the order of the silo versus finding out the truth.

“Some mysteries, they’re best left unsolved,” as Bernard suggests.
