Warning! This article contains spoilers for Hugh Howey’s Silo books.
TheSilofranchise has been growing from strength to strength in popularity and acclaim, but a new update from the original author, Hugh Howey, suggests its future will be all the more exciting and expansive. Hugh Howey started theSilouniverse in 2011 with a short story, titled “Wool,” which paved the way for a full-fledged novel that has now been adapted by theApple TV+ sci-fi show’s first two seasons. What started as a novella soon became an acclaimed book series, exploring the fascinating depths and grim realities of a fictional post-apocalyptic world.

The original books' original author, Hugh Howey, has offered some intriguing insights into where the franchise could progress, promising a great future for the books and the TV series.
