Book 21of 2017 is Shift by Hugh Howey
This is the first middle book in a trilogy since Two Towers that I have loved and not wanted to put down. I demolished this in days and even woke up early to read it. This makes sense since Wool leaves you in a state of wondering what is happening and why.
The character development is more solid than Wool. The history and cunning plans are laid out and understandable. This brings it all together and now I'm waiting for Dust to smash it home.
5 silos out of 5.
Should I read this? Yes. Read the whole series. This is very good sci-fi.
What did I learn? I have to finish more of the series I start.
