Start with The Iron king. It is book one, and unlike most historical sequences of this size there is no rival entry point to argue about — this is one continuous story told in strict order, and the later volumes assume every character introduced in the earlier ones.
The one real question a newcomer has is whether to commit at all, and the answer is decided in the first fifty pages. The whole sequence's friction is front-loaded there: a large cast of French nobles with similar names and multiple titles each, so that the same man is Artois, Robert, and the Count, often in a single paragraph. Give those fifty pages your full attention and the remaining six books cost you nothing. Skim them and you will be confused for two thousand pages.
The Iron king is around 300 pages and moves fast — 40 to 50 pages a day is comfortable, and most readers finish it in a week or two.
What you are actually reading
In 1314 the Grand Master of the Templars is burned in Paris and, from the fire, calls the king, the pope and the king's counsellor to God's judgement within the year, damning the Capetian line to the thirteenth generation. History then obliges with uncomfortable speed. That is the frame; the substance is procedural politics, with murder treated as an administrative option and no authorial moralising anywhere.
The comparison to Game of Thrones is not marketing. Druon's sequence is dynastic, amoral and structurally indifferent to who the protagonist is, and characters you have followed for two books are removed without ceremony.
The succession crisis
The Strangled Queen, The poisoned crown, The Royal Succession. Read these three as one movement — the second book picks up almost mid-scene from the first, so do not leave a gap.
These are the fastest-moving volumes in the sequence and the ones where Druon's political instincts are sharpest: a remarriage problem solved by removing a person, a regency manoeuvred around an unborn heir, and an infant king who reigns for five days. The hinge of the whole work is here — the exclusion of women from the French succession, improvised as an expedient and only later hardened into principle. That improvisation is exactly what gives Edward III his pretext two books later. The Hundred Years War begins as a legal argument made for short-term convenience.
Mahaut of Artois runs through all of it as the most effective political operator in the books, and Druon lets her be that without softening her.
Toward the Hundred Years War
The She-Wolf of France shifts the setting to England and introduces a second court, so expect a short re-orientation. The Lily and the Lion is the longest and most satisfying volume and repays being read in large sittings.
Isabella of France is the character the sequence has been quietly building toward: daughter of Philip the Fair, queen of England, and the person who exposes the scandal that starts everything in book one. Her invasion and the deposition of Edward II are handled as politics rather than melodrama. Then the Artois feud that has run since page one collapses over a set of forged charters, and Robert's defection to England closes the circle — the curse's last work is done by a Frenchman urging an English king toward war.
Where to stop
Stop after The Lily and the Lion. Druon wrote the sixth book as the ending and it functions as one: the curse's thirteen generations are accounted for, the dynasty is gone, the war is beginning.
The King Without a Kingdom arrived roughly twenty years later and is genuinely optional. It is a single sustained monologue by a cardinal on the road, addressed to a listener who never replies, with almost no scene-level drama. It covers Crécy and Poitiers, but reports them rather than dramatising them, and it is the only volume in the series with an unreliable voice. Read it after a gap rather than immediately, or the formal contrast will read as a failure instead of a choice. The sequence loses nothing if you never do.
If medieval politics at this pitch is what you came for, there is more of it on the site.
