Horrifying depiction of a post-apocalyptic world in the Novel 'Wool'

If you ever want to read a great sci-fi novel that portrays the horrors of life in a post-apocalyptic world I suggest you read WOOL

"The novel takes place in a postapocalyptic future where a few thousand remaining humans live in a giant, 144-story underground silo.

Couples who want to have a child have to enter a lottery; tickets are distributed only when someone dies. Citizens who break the law are sent outside to choke to death on the toxic air. Those who are sent to their deaths are forced to clean the grime off the digital sensors that transmit grainy images of the ruined landscape to a screen inside the silo.

The images are meant to remind residents that the world beyond the silo is deadly, but some begin to suspect their leaders are lying to them about what's outside and how the world came to ruin."
