For many long years, Atlee Pine was tormented by uncertainty after her twin sister, Mercy, was abducted at the age of six and never seen again. Now, just as Atlee is pressured to end her investigation into Mercy's disappearance, she finally gets her most promising breakthrough yet: the identity of her sister's kidnapper, Ito Vincenzo.

With time running out, Atlee and her assistant Carol Blum race to Vincenzo's last known location in Trenton, New Jersey—and unknowingly stumble straight into John Puller's case, blowing his arrest during a drug ring investigation involving a military installation.

Stunningly, Pine and Puller's joint investigation uncovers a connection between Vincenzo's family and a breathtaking scheme that strikes at the very heart of global democracy. Peeling back the layers of deceit, lies and cover-ups, Atlee finally discovers the truth about what happened to Mercy. And that truth will shock Pine to her very core.

In this #1 New York Times bestselling thriller, FBI Agent Atlee Pine returns to her Georgia hometown to investigate her twin sister’s abduction, only to encounter a serial killer.
FBI Agent Atlee Pine’s life was never the same after her twin sister Mercy was kidnapped — and likely killed — thirty years ago. After a lifetime of torturous uncertainty, Atlee’s unresolved anger finally gets the better of her on the job, and she finds she has to deal with the demons of her past if she wants to remain with the FBI.
Atlee and her assistant Carol Blum head back to Atlee’s rural hometown in Georgia to see what they can uncover about the traumatic night Mercy was taken and Pine was almost killed. But soon after Atlee begins her investigation, a local woman is found ritualistically murdered, her face covered with a wedding veil — and the first killing is quickly followed by a second bizarre murder.
Atlee is determined to continue her search for answers, but now she must also set her sights on finding a potential serial killer before another victim is claimed. But in a small town full of secrets — some of which could answer the questions that have plagued Atlee her entire life — and digging deeper into the past could be more dangerous than she realizes . . .
