Disappointing. The author stuffs in a lot of facts that are not really relevant to the story. Luckily, after a while you learn to spot them starting and can skip down several paragraphs or a page or two to meet up with the narrative again. The jumping back between Bly's journey and Bisland's journey was a bit jarring too. I think for continuity it might have been better to split this book into two parts: one for Bly's trip and one for Bisland's.
