A reread, because I had forgotten absolutely everything about it. At some point I acquired the second book in the series and have yet to read it, so...
A Grail story, at heart, set in two time periods – modern(ish) day and the early 1200's during the Albigensian Crusade. (This was interesting to me, having recently read A Booke of Days, which is set during the First Crusade. It's handy to be adding to the same framework. The author notes that the Albigensian Crusade is the first where Christians were actively targeting other Christians, and also the first whose goals were focused in European lands. Like many of the preceding crusades there is much evidence that, although cloaked with theological ideals, the actual motivations were highly political and territorial.)
I've seen a handful of comparisons between Labyrinth and Dan Brown books and....I guess. Labyrinth has secret societies and questionable religious motivations. It has relics and symbols and a wee bit of romance. But Labyrinth doesn't feel like Dan Brown to me, despite the topical similarities.
Kate Mosse, for starters, is a far better writer – though not always a more interesting one. There are no formulaic gimmicks in Labyrinth so its got a bit more literary heft. The historical detail seems genuine and deliberate and informed. The downside here is that Mosse is often overly descriptive; in history, in conversation, in actions, in emotions...in everything. Many paragraphs feel like a statement of a thing followed by an elaborate restatement of the exact same thing. This would have some charm in moderation, but really bogs down the experience as the main method of writing.
There is a supernatural or mystical thread running through the heart of the story that goes beyond the base Grail mythology and I am not sure it was entirely justified. Our two protagonists share a bloodline, and modern-day Alice gains some of her insight from dream memories and never-explained intuition. It felt as this was ultimately a device used to hasten exposition and draw character parallels. It was muddy and removed opportunity to liven up the modern story-line with actual research and puzzle solving.
There was a disparity of quality between the two time lines. The author is clearly in love with (and well-versed in) the history. The plotting, the immersive setting and the characterization are all far richer when we are with Alais in the 1200's.
A mixed bag, really. I like it, but for its breadth and sometimes overreaching detail, I can see why it didn't stick with me the first time I read it. Even if the second book knocks my socks off, I should just remind my future self that this one is probably not worth a third slog-through.
