Silo showrunner Graham Yost addresses when his hit Apple TV+ plus show will end as season 2 approaches. Based on the novels by Hugh Howey, the sci-fi thriller series premiered in 2023, following Rebecca Ferguson’s Juliette, an engineer, as she attempts to unravel a conspiracy within the underground silo that houses the last of humankind. The show was a hit, and Silo season 2 is now on the way with a story that adapts the second half of Wool, the first book in Howey’s trilogy.
