Books on Druidry in France

I was surprised to find so many books on Druidry, across several bookstores, while on my recent trip to France. They were clearly more focused on the Celtic traditions in ancient Gaul (which now comprises parts of France) than on the modern practices of Druidry today, though I was still happy to see them at all given the complexities of religion in the country.

These are a clear encouragement for me to improve my ability to read French, which has overall focused more on menus and train schedules!

What continues to puzzle me, however, is how Druidry has been embraced in various forms in the British Isles and the U.S., yet somehow is not readily locatable at all in France. Mind you, I was able to find this nice selection of books that seem to infer a modern practice of Druidry exists someplace there, though I was not able to unearth it whatsoever.

Does anybody know any practicing Druids (Druides) in France? If so, do any of them know enough English to help me understand this phenomenon?
