Absolutely spot on! The principal characters are written quite childishly, and yet Elwen is easily able to take the Book of the Grail from Pont d'Eveque with no mishap and without getting caught, BUT the seasoned saracen traveller, envoy of the Brethren and ex-soldier, Hasan, chooses to go up a dark alley on his way back to the Temple with the book, and is beaten up by a bunch of apprentices and dies.
Overall I'm finding the pace of the story quite slow; and at some points quite boring and I'm skipping paragraphs as a result. I don't agree that the writer is writing 'flowingly' and the jumps between the two stories are sometimes a bit clumsy. It's OK for a first novel, but it could have so much more.
