The Cleaner of Chartres

Just wondering whether anyone else has read this and what they thought of it. I have just read it for our book club, and found it very difficult to get into, with short, disjointed chapters, set in different places and times, and so many characters. I kept having to go back and check who was who and when and where things were happening.
Then suddenly about halfway through it all seemed to come together and I found it difficult to put down, and just had to know what happened next, and managed to keep up with the story.
Not sure whether I fancy any of the author's other books though.
