The adventure continues in The Last Quest, Book II of Song of Montségur.

Based on the true history of the Albigensians-Cathars and of the Tarot deck, The Last Quest continues to grand epic begun in The Last Troubadour. Populated with real historical characters, and following the early history of the famous Troubadour Ramon Lull — himself the author of 300 books and an inspiration for Tarot decks in the thirteenth century — The Last Quest continues the Song of Montségur Trilogy, described as "Brilliance" by Booklist.

Ramon, the last living troubadour, and the other children of Magba have escaped Carcassonne with the precious Dame, the Jewel of the South in book one, The Last Troubadour. Now, in The Last Quest they must fight their way through the Phantom Wood and achieve sanctuary at Chateau Montségur.

Against them Death comes with his Scythe and his deathstalkers. Also, riding to cut them off is a vengeful lion, Sir Albaric de Laon and his hundreds. In the Phantom Wood are the terrible hungry ghosts and desperate renegades. The Dame of the Cathars, Ramon the Troubadour, Seigneur the one-eyed knight, Perce the squire, Adelais the temptress, Nevara the sorceress, Arnot the Templar and the children of the Baug face a pursuing army led by the king's nephew, the purple knight Sir Lantar.

If they escape the ghosts and armies, they must cross the lands of the Mad Duke, into the Weir Mountains, pursued by crusaders charged by the new Pope Innocent to obtain the Holy Relics. And beyond this lies Chateau Montségur, last refuge of the Christian Cathars, with their small village of the faithful to guard the sacred Holy of Holies from the viscount's thousands.
