I've seen mixed thoughts on this one but I absolutely loved it. The introduction to The Nowhere and other characters was a lot of fun for me.

This was an entirely different journey for Spensa as she tries to find a way to save, not just her people, but everyone. The history she learns of helps put a lot of what is happening in the previous books into perspective. The ending though! I honestly did not see that coming and I LOVE it. Cannot wait for the next book.
