Wool

Recommended by Luke.

Okay, wow. When Luke recommended Wool (Amazon affliliate link), I had four other books going, and wanted to finish those before getting too far into Wool. I kinda wish I hadn't delayed. This book is great. Read the basic plot on the Amazon page, if you'd like. The back reads something like:

In a ruined and toxic future, a community exists in a giant silo underground, hundreds of stories deep. There, men and women live in a society full of regulations they believe are meant to protect them. Sheriff Holston, who has unwaveringly upheld the silo’s rules for years, unexpectedly breaks the greatest taboo of all: He asks to go outside.

His fateful decision unleashes a drastic series of events. An unlikely candidate is appointed to replace him: Juliette, a mechanic with no training in law, whose special knack is fixing machines. Now Juliette is about to be entrusted with fixing her silo, and she will soon learn just how badly her world is broken. The silo is about to confront what its history has only hinted about and its inhabitants have never dared to whisper. Uprising.

The thing about Hugh Howey's writing is that it's isn't eye-rolling absurd. Given the basic premise (societies living in underground silos), the characters are believable, the dialogue reasonable and the actions plausible. I really enjoyed that about the book, being able to be lost in the dystopian world for hours.

Luke says the following two books in the series, Shift and Dust (also affiliate links), are great, too. And now quickly added to my to-read reading list.
