"The breakdown of government and common courtesy is represented well, while Crewe still sows a seed of hope for the future. The character of Kaelyn carries the book--she is well developed, with a lot of depth and emotion. Readers will feel her struggles as she pushes past her moral boundaries in an effort to benefit humanity." -VOYA
"Crewe gives the book a late shot in the arm (so to speak) by offering up surprisingly complicated and nuanced portrayals of both the Wardens and CDC members. They, like everyone else in Crewe's grim dystopia, are neither good nor evil. Just fighting to survive." -Booklist
