The five volumes of the epic Cathar take you not only in the history of the Cathars, but also in that of the conquest of the south-west by the kingdom of France. Each volume is extremely documented. Sometimes we get lost in the detailed presentations of a given perfect but, besides the fact that we can avoid some of these passages without losing the thread too, they are very interesting. This volume, recounting the end of the Cathars, is probably less epic but more touching.
