Set in the mid 1300s in France (and particularly around the impressive Carcassonne) during the Inquisition, this is more of a fantasy with historical elements than others of hers that I have read (which tended to the Philippa Gregory end of the soapy scale).
Pagan magic up against inquisitors and a lot of fated mates - grand sweeping arm gestures and a lot of torture and burning at stakes. This one just didn't click for me.
