After searching for him for almost a century, Alexander McGill has finally destroyed the Graf, the most dangerous vampire in the world, preventing him from uniting the vampire families in a battle against the mortals. Any thought of being able to live peacefully among mortals is interrupted by the knowledge of the Graf's apprentice, Princess Irina Poltoratzky escaped along with supporters from three vampire families. Alexander and loyal companion Johan embark on a quest around the globe to discover their plans. The Princess is a different adversary than the Graf, one who has learned from the Graf’s mistakes and is willing to take decades to put her plan in place, after all what is a few years to an immortal. Working separately, Johan and Alexander discover proof that the Princess is working with the Families in France and Japan to build an army of vampires like the world has never seen, an army that will conquer the mortal world not in the battle field, but from within. Unless she is stopped soon, the world of mortals is in imminent danger. As Alexander and Johan work to uncover clues, their young friend, John Jones, wins a trip of a lifetime to Paris. The pair are close to being able to take action against the Princess when their paths again cross with John, this time with devastating consequences.
