I found this book in the library. It is called Chasing the Heretics: A Modern Journey Through the Medieval Languedoc by Rion Klawinski. Mr. Klawinski tours Languedoc and goes to all the Cathar hotspots: Toulouse, Carcassone, etc. He even goes to Bram. He explains what happened in that town and then describes what it's like now (well, in 1999). I thought it was a great accompaniment to the Pagan series.
