Retired Army Ranger John Holliday has reluctantly settled into his teaching position at West Point, when young Israeli archaeologist Rafi Wanounou comes to him with desperate news. Holliday's niece—and Rafi's fiancée—Peggy has been kidnapped while photographing the excavation of an ancient tomb in Egypt. Her captors are known as the Brotherhood of the Temple of Isis—murderous fanatics who worship a dead god.
Holliday sets out with Rafi to find the only family he has left. But their search for Peggy will lead them to a trail of clues that spans across the globe and into the heart of a conspiracy involving an ancient Egyptian legend and the darkest secrets of the Order of Templar Knights.
Secrets that, once known, cannot be survived.
