Sign of the Cross: A Religious Conspiracy Thriller (Cal Donovan Vatican Conspiracy Thrillers)

In Italy's Abruzzo hills, a young priest named Giovanni displays bleeding wounds on his wrists resembling stigmata. Harvard professor Cal Donovan, who specializes in distinguishing authentic religious phenomena from fraud, is summoned by the Vatican to investigate. His inquiry suggests the stigmata may be genuine. Before Donovan can determine the truth, Giovanni is abducted from his church by a neo-Nazi network with roots in Hitler and Himmler's interest in occult power. What began as a straightforward investigation becomes a dangerous pursuit. Giovanni holds the key to a secret that others are willing to kill for—one connected to a plot designed to trigger an apocalyptic catastrophe. Donovan must locate Giovanni, decode the secret at the center of the conspiracy, and prevent a catastrophic outcome before time runs out.
