Braverman Shaw, "Bravo" to his friends, always knew his father had secrets. But not until his mysterious death does Bravo discover the enormity of his father's hidden life as a high-ranking member of the Order of Gnostic Observatines, a sect founded by followers of St. Francis of Assisi and believed to have been wiped out centuries ago. For more than 800 years, the Order has preserved an ancient cache of documents, including a long-lost Testament attributed to Christ that could shake Christianity to its foundation.

As its latest keeper, Bravo, an accomplished medieval scholar and cryptanalyst, must follow the esoteric clues his father left behind while outsmarting the Knights of St. Clement, a secret society sponsored by the Papacy that has been after the Testament since the Crusades. Bravo has become both a target and a pawn in an ongoing war far larger and more deadly than any he could have imagined. From New York City to Washington, D.C., Paris, Venice, and beyond, the race is on for the quintessential prize...the Testament.
