This is one of those "three stars is a good rating!" reviews. I round down when rating, and there's nothing wrong with a solid three-star "I enjoyed this, it was a good book" experience. I'm sure I'd have a much different opinion if I'd read this as a young adult or a teenager; in a way, reading this as an adult and a parent lent a certain special horror to it. Obviously the focus of the book is on the teenage protagonists and their experiences, but I found myself wondering more about the parents. The reader mostly gets information on why the parents made the choices they did through the eyes of the Unwinds, but there's a couple of scenes where you hear or see the parents themselves, and those were among the most disturbing parts of the book. Good dystopia has just enough familiarity to make it disturbing, and in a way, it was the parents that gave this one that icky edge. 
 Speaking of icky, I give this book credit for including one of the most disturbing scenes I've ever read. It'll stay with me for awhile. 
 I'd recommend this to anyone looking for a good read. I'd strongly recommend it to anyone who likes dystopias or YA dystopias.
