In Crusade (The Heretic’s Secret, Book I), John Wilson introduced readers to a world literally on fire. As childhood friends John and Peter struggled to make sense of the upheaval around them, zealous Catholic knights rampaged across France, burning Cathar heretics and the cities they called home. Torn apart by their increasingly different beliefs, the two young men found themselves on opposite sides of a search for a secret that has the power to change the world.   In Grail (Book II) the search continues. Cities are falling to the brutal northern Crusaders and the smoke of the Cathar funeral pyres drifts across the land as Peter, John, and John’s friend Adso set off on journeys into the unknown. Adso takes to the hills with a band of soldiers, intent on revenge against Oddo and the Falcons. John and Isabella travel to Al-andalus in search of peace and the ancient wisdom preserved by the Moors. Peter travels to Rome, following a clue that Arnaud Aumery believes might lead to the mysterious Cathar treasure.   None of the three quests turns out as expected. Adso’s band is ambushed and he is forced to wander the country alone and bitter—until he meets a young monk who offers him a remarkable, yet dangerous, way to get back at his enemies. John and Isabella’s peaceful life of learning is cruelly disrupted as the Crusade spills south and they are caught in a battle that will determine the future of Al-andalus. Peter finds clues, but they only lead him farther away and deeper into a mystery that is becoming ever more complex.   In the end, however, all three men unknowingly find a piece of a puzzle—a puzzle that will only become clear if the pieces are ever brought together.   Available simultaneously: The Heretic’s Secret, Book I: Crusade in paperback.
