An excellent read! Well-crafted dystopian underground world with excellent character development in each story. I especially liked how each story was told from a different perspective instead of using the same person, starting with Sheriff Holston, then Mayor Jahn, and ultimately, Juliette. There were quite a few "oh-no" scenes, and several nail-biters, too. Looking forward to the next series (I'm waiting for the omnibus of that one, too), and I've added Hugh Howey's other books to my TBR list.
