A mysterious race of North American giants. An ancient Hebrew inscription in a Cherokee burial mound. A blood oath made by blindfolded Freemasons. Are these three historical oddities the reason the CIA is trying to brainwash historian Cameron Thorne and his fiancée Amanda Spencer-Gunn? The answer lies buried in the legends of the Knights Templar, within the rituals of the secretive Freemasons and, most significantly of all, inside the bowels of the Smithsonian Institution. The problem for Cam and Amanda? If they go rummaging around the Smithsonian, they may find themselves buried alongside the ancient giants. Cameron Thorne is trying to help an elderly couple keep their home when he finds himself dangerously immersed in an ancient conspiracy. Forced on the run with researcher Amanda, with deadly stalkers from two extremist factions hot on their trail, they begin to piece together information that ties together clues scattered across the Northeast. These clues reveal centuries old efforts by the Catholic Church to suppress information about Prince Henry Sinclair and the Templars that could tear the church apart if they survive long enough to reveal them.
