A good finish to the series. A few of the things wrapped up a little too neatly, but also some surprises at the end.

I enjoyed that we get to see Juliette united with Charlotte and move toward the start of their next adventure with the survivors from Silos 17/18.

I am wondering what else the author has planned with these characters. The bit about the people from 17 being "wrong" (i.e. "infected" by Anna with the nanobots that keep the people in Silo 1 alive/healthy for so long) seems too good to pass up!

I enjoyed how Howey weaved in the reasons behind what happened mostly in the background, but did make it pretty explicit what happened by the end, so if you missed some of the hints you weren't left completely clueless. I think that bit above about the Silo 17 survivors having healing nanobots being one of the last things left (mostly) unsaid.

Great series!
