Atlee Pine has spent most of her life trying to find out what happened that fateful night in Andersonville, Georgia. Her six-year-old twin sister, Mercy, was taken and Atlee was left for dead while their parents were apparently partying downstairs. One person who continues to haunt her is notorious serial killer Daniel James Tor, locked away in a Colorado maximum security prison. Does he really know what happened to Mercy? The family moved away. The parents divorced. And Atlee chose a career with the FBI dedicating her life to catching those who hurt others. When she oversteps the mark on the arrest of a dangerous criminal, she's given a leave of absence offering the perfect opportunity to return to where it allbegan, and find some answers. But the trip to Andersonville turns into a roller-coaster ride of murder, long-buried secrets and lies. And a revelation so personal that everything she once believed is fast turning to dust.
