I was determined to finish this book, but it was hard work. I liked the premise well enough and even some of the characters. But the story itself was bogged down with frequent and sometimes long passages of detail and information that was not really relevant to the plot. Even the details that were relevant were usually included several times, which was unnecessary. I think this was in an attempt to give the reader a more full understanding of that world, but it only served to make the pace crawl along and it took a huge effort for me to stay engaged in the story.
Another thing - what is it about alternate Earths and zeppelins? So many alternate Earth stories I encounter have zeppelins in them! Maybe they seem a trifle exotic.
