It's been three months since Amy escaped New Hope, and she's been surviving on her own, like she did in the After. Until one day, her former fellow Guardian's voice rings out in her earpiece. And in a desperate tone, Kay utters the four words Amy had hoped she would never hear: Dr. Reynolds has Baby. Now it's a race against time, for Baby is in imminent danger, her life threatened by the malevolent doctor who had helped start the end of the world. In order to save Baby, Amy must make her way to Fort Black, a prison-turned-survivor-colony, where she will need to find Ken, Kay's brother. He alone holds the key to Baby's survival. One small slip-up on this quest could spark a downward spiral that would not only cost Baby and Amy their lives, but threaten the very survival of the people in the After.
