Tormod MacLeod's brother, Torquil, has been captured and locked in a dungeon hidden in the depths of the French royal castle. Tormod and Aine journey to France, hoping to save him, but the search is proving more difficult than they ever imagined--and getting out alive seems impossible. Meanwhile, they must stop the wicked plot that King Philippe le Bel has put in motion to destroy the Knights Templar from within. Their journey takes them all the way to the French court, where they meet the enchanting Princess Isabella. She has her eye on Tormod, and Aine notices. Their chances of accomplishing all they've set out to do while keeping the power of the Holy Vessel from being exposed to the world are slim, and in the end, Tormod has a devastating decision to make.
