Ariel Herzog makes a career of debunking supernatural claims until a mysterious page from a secret book lands in his hands. The cryptic text points to an ancient object created over 2000 years ago that somehow connects to major world events from Hitler's rise to the Holocaust to nuclear war. Herzog teams up with Lara Winter to decode the mystery page by page. Their investigation takes them from New York to Istanbul, Berlin, Moscow, and Jerusalem. In each city they encounter enigmatic agents who hold keys to the next revelation. But a shadowy organization has protected this secret since ancient times, and they track Herzog's every move. The closer he gets to the truth about the dark angel and its influence on world history, the more dangerous his quest becomes. Herzog must decide whether unlocking this mystery is worth risking his life to understand the forces that have shaped the modern world and may determine its future.
