In 1997, a fire ripped through Turin's cathedral—one of the only moments in modern history when the Shroud of Turin wasn't under constant guard. In the chaos, someone may have done the unthinkable: swapped the sacred relic for a flawless counterfeit.

Twenty years later, the Vatican announces a new, high-stakes round of scientific testing, and Dr. Nicole McHenry—an American lead chemist still raw from the losses that have shaped her life—is chosen to help determine the Shroud's authenticity. But before she ever sets foot in Italy, the threats begin.

The threat isn't empty. Hidden beneath the Tuscan countryside, billionaire zealot Pierre Delacroix has been guarding the real Shroud for years—convinced it is divine, convinced it can raise the dead, and convinced prophecy demands he unveil its power on Easter 2018. To stop the Church from exposing the truth, Delacroix unleashes Carter's coercion and Romano's violence. And when bullets tear through Venice, Nicole's world becomes personal in the most brutal way.

Now Nicole and her husband, Liam, are pulled far beyond the boundaries of academia—into the Vatican's most dangerous secrets, where Gideon DeVito and Overwatch wage a shadow war to recover the relic before it becomes a weapon of immortality…and the perfect proof for a manufactured "Second Coming."

Two years after the Shroud of Turin was recovered from a brazen heist committed by billionaire zealot Pierre Delacroix, Nicole McHenry and her team at the University of South Carolina have discovered something amazing encoded into the Shroud.

Nicole's discovery puts her on a path that will put her at odds with her own Church, a path that will lead to even more dangerous territory when the Church, once again, refuses to reveal to the world the true nature of the Shroud.

With Gideon DeVito, her de facto protector, by her side, Nicole will have to team up with her previous adversaries in order to enact her shocking plan to bring the Shroud’s truth to the world. In doing so, Nicole will face dangers bred by lies, betrayal, and secrecy.

The outcome of Nicole's endeavors is unclear: even if she can reveal the secrets contained in the Shroud, will anyone believe her?

Dr. Nicole McHenry conceived twins, Kevin and Kimberly, and the world was right again. But then she was visited by the Lord in a dream, who gave her a task to bring the Shroud’s teachings to the world. Now something unexpected has occurred—the twins are not normal.

As the twins mature into young adults, something distinctly different about them becomes apparent, and not just to their parents. Eyes from afar start to focus on the duo, and their lives will take unexpected paths as those surveilling them put a diabolical plan into action.

Can their parents, Nicole and Liam, protect them from what is to come? Or do they need their protection at all? What is it about them that is causing disruption at the highest levels of the world’s power structure?

Their fate may be decided by those whose motives do not align with theirs, or perhaps by a prophecy written thousands of years ago.
