I didn’t know what to expect when I picked up a copy of this book – I knew nothing about it except that it was popular and had an intriguing title. When I looked closer at the cover and saw that it was about ‘Three secrets. Two women. One Grail.’ I winced – too often novels about the Grail are simply ‘New Age’ conspiracies and not very good ones at that. Still, decided to give it a try. Glad I did! Yes there is a Grail Conspiracy here, and plenty of heresy to boot (which it doesn’t claim as real world truth, so I can live with that), but there is also a gripping story, set it Carcassone both today and in its Occitan past. This is a place and era I know little about, and just as the Swedish in The Girl with the Dragon Tatoo gave that book a particular feel, so to the smatterings of French and Occitan, and the place names a very evocative descriptions did the same here. I found myself drawn in quickly and read with enthusiasm. I will almost certainly go away and read up a little more about the place and time that this book describes. Personally I found the end a little unsatisfactory, but to be honest, that didn’t matter too much, as the journey there was a good one, and often the journey is the thing, rather than the destination. I’d happily recommend it, and will look out for other books by Kate Mosse in the future.
