Silo 49: Going Dark
Silo 49 has never had it easy and things have just gotten a whole lot worse. Graham, the head of IT, has done many unsavory things in his life but everyone has a line they won't cross. He just found his. With Wallis and Grace, his last friends, it is a race against time against the impersonal might of Silo One. Their only choice: Going Dark. Set in Hugh Howey's WOOL universe.
