Shift by Hugh Howey

Shift Omnibus (Silo, #2) (Wool, #6-8) - Hugh Howey

Oh, I loved this book. I loved Wool for it's higher pace story-telling, but Shift I loved just as much for the ingenuity of the story development. So far the series is my favorite in the post-apocalyptic/dystopian genre.

P.S. I truly wish this series were made into a movie.
