FBI Agent Atlee Pine's search for her twin sister, Mercy, coincides with military investigator John Puller's high-stakes case, leading them both into a global conspiracy from which neither of them will escape unscathed.

Ever since Mercy was abducted after a brutal incident when the girls were just six years old, Atlee has been relentless in her search for the truth. Now, just as time is running out on her investigation, she finally gets her most promising breakthrough yet - the identity of her sister's kidnapper: Ito Vincenzo. Last known location: New Jersey.

As Atlee and her assistant, Carol Blum, race to track down Vincenzo, they clash with old friend John Puller, who is investigating Vincenzo's family for another crime involving a military installation.

Working together, Pine and Puller pull back the layers of deceit, lies and cover-ups that strike at the very heart of global democracy. And the truth about Mercy is finally revealed.

And that truth will shock Atlee Pine to her very core.
