Outlaw Knight (IV)

In 1207, Philip of Cognac—bastard son of Richard the Lionheart—is sent on a desperate mission to the heart of Christendom. He must win peace with Pope Innocent III… or condemn Nicaea to ruin. But Philip does not travel alone. An old enemy follows in the shadows. In the depths beneath Rome, among its tombs and forgotten places, Philip uncovers a deadly conspiracy: a usurper returned from exile, allied with the Turkish sultan, and bent on seizing the shattered husk of the Roman world. As armies gather and loyalties fracture, Philip must choose his allies carefully. For the next battle will not decide a city—but the fate of an empire.
