I'm a co-blogger at All Things Urban Fantasy, while Read Fragment is where other genres wash ashore.
After an auspicious start, I hit a rough patch at about 25%. The heroine is having a break down, and it's most unpleasant going along for the ride through her narration. From sensible and strong and loyal, Vianne becomes irrational, self-damaging, and ridiculous. She won't eat, and her doubts would be comical if they weren't so damn repetitive and annoying, and unfortunately, are associated more with the sad "heroine doesn't know she's beautiful" trope than any more interesting character growth. I think the author assumed that the readers would enjoy thinking "Vianne just doesn't realize how *awesome* she is", but that just adds a layer of Mary Sue annoyance on top of her endless doubts, self-flagilation, and martyrdom. I find myself rolling my eyes and flipping pages faster.
