It is the year 1307 and the ancient Order of the Knights of Christ and the Temple of Solomon is in grave danger. The King of France and Pope Clement V are plotting its destruction and scheming to appropriate the Order's most sacred and dangerous secret.
This is taken away by Etienne de Congost, a battle-weary but incorruptible man who flees through a world in ruin, dodging plots and papal spies in a life-and-death struggle. Will he keep the secret from the evil hands of king and pope?
The outcome of Etienne's desperate journey is discovered 700 years later by a writer who visits Lockenhaus Castle in Austria to research a book on the Templars. Together with an eccentric local woman, she begins to untangle the web of destiny that binds them both to the mystery of the Seal.
