"...a brave book, an unsettling book, and one that is very much needed at this time."--The Globe and Mail "...an astonishingly nuanced and masterfully told story..."--Quill & Quire Not all the Crusades were fought on the far edges of Christendom. In the thirteenth century, a bloody Holy War was fought against a sect of heretical Christians, the Cathars, who lived in Languedoc around the modern city of Toulouse. The war lasted decades and tens of thousands were murdered, mutilated or thrown on vast bonfires. A powerful culture of poets and troubadours, with its own distinct language, was destroyed and modern France created. The crusade spawned the Dominicans and the formal Inquisition, and the bitterness it created lasted 200 years into the brutal religious wars that devastated Europe in the Reformation.When the armoured knights of Pope Innocent III swept south in 1209, most thought they would be gone by summer's end but, led by the fanatical Arnaud Aumery and the ambitious Simon de Montfort, they stayed for three fiery decades. Caught up in the horror are two childhood friends. Peter--an assistant to the shadowy, enigmatic priest who leads the crusade--is convinced that the war against the Cathars is God's will, a mission that will lead him to the highest ranks of power in Rome itself. John--who finds himself drawn to the strange ideas of the heretics--simply seeks the peace to learn and understand through reading the forbidden books hidden in remote castles across the land. As the crusading knights destroy city after city and the flames of the Inquisition spread, Peter and John find themselves on opposite sides of a search for an ancient secret that may have the power to change the world. The Heretic's Secret (Single Volume Edition) comprises the complete Heretic's Secret Trilogy (Heretic, Quest, and Rebirth).
