"The #1 New York Times bestselling author with 150 million copies sold worldwide returns with his next blockbuster thriller featuring FBI Agent Atlee Pine"--

For her entire life, FBI agent Atlee Pine has been searching for her twin sister, Mercy, who was abducted at the age of six and never seen again. Mercy's disappearance left behind a damaged family that later shattered beyond repair when Atlee's parents inexplicably abandoned her. Now, after a perilous investigation that nearly proved fatal, Atlee has finally discovered not only the reason behind her parents' abandonment and Mercy's kidnapping, but also the most promising breakthrough yet: proof that Mercy survived her abduction and then escaped her captors many years ago.

Atlee Pine has spent most of her life trying to find out what happened one 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, confined to 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 all began 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 to be true is fast turning to dust.
