I haven't finished reading this book, and I'm not sure I will. The story itself seems interesting enough, but the way it's written is driving me crazy and making it impossible to get immersed in it. A lot of this problem is formatting -- the author places spaces between paragraphs much the way many elementary students are taught to do today (an annoyance I won't get into here). This visual breaking every 3 or 4 paragraphs (at MOST, usually more frequently), particularly where no break is necessary because the same scene continues after the break, is very disruptive. Added to the fact that there are at least (by my count) 3 or 4 different stories going on and at least one of these stories has yet to have any connection to the others as far as I can tell and the book is an impossible mess for me so far.
There are other issues as well -- lack of solid description in many places that make the story easier to visualize (though this isn't always the case, so I guess uneven description is closer to the mark), for example, but the above are by far the hardest for me to overcome so I can get into and enjoy the story. The sad thing is I really want to get into it. I love the premise of angels walking the earth and the Vellum that the author uses as a connection between time and place. For now, though, I have to set it aside. I don't like having to struggle to get into a good read. There are too many good books out there that don’t require quite so much work.
