In a dystopian future, the last ten thousand people on earth live in a mile-deep home that protects them from the toxic and deadly world outside. Nobody knows when or why the silo was built, and anyone who tries to find out will face deadly consequences.

Juliette is an engineer looking for answers about a loved one's murder who tumbles upon a mystery that goes deeper than she could have ever imagined.

Based on Hugh Howey's bestselling trilogy of dystopian novels.
