Jonathan Hunt has forty-eight hours to rob the Vatican, stop a biological apocalypse, and make it to the altar on time—assuming the super-soldiers don't kill him first.

Jonathan Hunt thought the hardest part of his week in Rome would be choosing a font for the wedding invitations. He was wrong.

In the Eternal City to marry the love of his life, the former CIA operative is dragged back into the shadows by an old ally with a desperate plea. A ghost from the past, Abraham Pale, has resurfaced. Known in the underworld as "The Plague," Pale isn't just selling weapons anymore; he’s creating them. He is engineering a new breed of soldier—men chemically stripped of pain, fear, and mercy, designed to be unstoppable killing machines.

And the key to stopping this nightmare is locked in a vault deep beneath the Vatican.

Trapped between a double-crossing handler, a bayou-born sniper with a .

50 caliber solution for everything, and a fiancée who thinks he’s out tasting cake, Jonathan has to pull off the heist of the century. To save the city, he must breach the Holy See’s most secure bank vault during the acoustic cover of a concerto—which happens to be his own wedding rehearsal.

With the clock ticking down to his vows, Jonathan must trade his tuxedo for tactical gear to stop a monster from turning Rome into a graveyard.
