Based on the excellent Hugh Howey novel, Wool, a subterranean city is carved deep into the earth. No one knows why they are there, but they believe that outside is a poisonous wasteland. Anyone who says that they want to go out is put in a suit and sent out the door, where they appear to die. We follow our lead characters as they start to question the rules of the silo and what is really outside. An exciting, taut story with interesting characters, good representation with mysteries and twists galore.
