It's been three months since Amy escaped New Hope, and she's been surviving on her own. Then one day Amy gets a call from Kay and hears the four words she 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. Amy must make her way to Fort Black, a prison turned survivor colony, where she will need to find Ken, Kay's brother, who holds the key to Baby's survival. One small slipup on this quest might not only cost Baby and Amy their lives but could also threaten the survival of the people in the After.
