Les Rois Maudits - Le Lis et le Lion et Quand un Roi perd la France, de Maurice Druon

These are the two final volumes of the Rois Maudits saga. Le Lis et le Lion finishes the story of the cursed progeny of Philippe le Bel, and Quand un Roi perd la France tells the follow-up, until the battle of Poitiers, one of the lowest points for France in the Hundred Years War. It's a well written historical novel, with plenty of intrigue and infamous characters, a very good read.
