‘Silo’ Author Defends Season 3’s Biggest Departure From the Books, and He Has a Reason for the Change

Adapting a beloved book series for television always comes with an unspoken risk: the further a show strays from its source material, the more likely it is to alienate the readers who fell in love with the original story first. That tension has followed ‘Silo‘ since the Apple TV Plus adaptation began drawing more heavily from Hugh Howey’s trilogy for its third season.

Season 3 marks the show’s biggest creative leap yet, pulling material from ‘Shift,’ the second book in Howey’s series, while taking considerably bigger swings than the relatively faithful adaptation fans got in the show’s first two seasons. That shift has produced a noticeably divided response, with the season currently holding a 96 percent Certified Fresh score from critics on Rotten Tomatoes, but only a 58 percent audience score from more than 250 user reviews, marking the first time any season of the show has landed a “Rotten” rating from viewers.

Much of that fan frustration has centered on one specific change: the character known as Donald Keene in Howey’s novels now appears in the show as Daniel Keene, played by Ashley Zukerman. In the books, Donald directly designs the underground silos while being kept in the dark about the project’s darker true purpose. The show’s version of Daniel instead learns about the project only after it’s already well underway, without ever actually designing the structures himself.

After a fan voiced frustration with that alteration in a Silo series Facebook fan group, Howey responded directly, defending the decision and arguing the show’s version actually improves on what he originally wrote. “It’s an improvement over the books,” Howey wrote in the fan group, as reported by CBR. “We didn’t want Daniel to be a WILLING contributor to a large part of the project. You’ll start to see why in the next two episodes. It’s critical to his arc.”

That explanation suggests the change isn’t simply a cosmetic tweak, but a deliberate storytelling decision meant to reshape Daniel’s arc heading into the season’s final stretch. Howey’s willingness to publicly defend the choice, rather than distance himself from the show’s creative liberties, points to a level of involvement that goes beyond a typical source-material author watching from the sidelines.

That collaborative dynamic isn’t new. Showrunner Graham Yost has previously spoken about Howey’s supportive attitude toward the adaptation’s creative choices, telling CBR at San Diego Comic-Con that Howey has always been receptive to seeing his universe explored in ways he hadn’t originally imagined, comparing the show’s approach to how he’s long supported fan fiction set within his world. Howey has echoed that sentiment himself, previously noting that most of the changes made for the show were improvements, even while admitting he wished the series had kept paper as a sacred, scarce commodity within the silo, a detail he felt didn’t gain much by being altered.

With ‘Silo’ already renewed for a fourth and final season, Howey’s continued willingness to engage directly with fan criticism suggests he sees the show as its own distinct interpretation of his world rather than a strict page-to-screen translation. Whether that perspective wins over skeptical book readers remains to be seen, but it’s clear the author himself has no reservations about where the story is headed.
