Most of us are familiar with Jesus' parents, Mary and Joseph, and Jesus' purported spouse, Mary Magdalene. But what about Jesus' siblings? What role did they play in early Christianity? Contemporary Jesuit and renowned religious historian Nicholas Branson is about to find out...and the answer will shake the foundations of the Judeo-Christian world. It all starts with the murder of a United States Senator in a confessional, and the discovery of a strange religious document among his possessions. At the urging of his FBI friend, Branson joins the investigation. His effort to uncover the truth behind the murder draws him into the search for an eight-hundred-year-old treasure and into a web of ecclesiastical and political intrigue. Accompanied by a beautiful, sharp-tongued research librarian, Jessica Jones, Branson follows a trail of clues, from the peaks of the awe inspiring French Pyrenees to the caves of war-torn Afghanistan. Along the way, shadowy powerful forces trail the pair, determined to keep safe a secret buried for centuries.
