I think part of the problem was the stodgy language, especially when trying to imagine it coming from a 10-year-old, as Jane is at the beginning of the book. Even given the time period, I can’t imagine a child speaking like that.
Also, I felt like the author kept hitting me over the head repeatedly with the major themes of the book. Jane is too easily overcome by her emotions, ok I get it. Religion, god, religion, ok, got it. A bit of subtlety, please.
The pace was also strange. First, there’s a a good amount of time spent on 10 year old Jane, showing us her childhood. Something seemingly major happens, and then suddenly, without much reaction or showing the impact of it, we’re suddenly jumping ahead eight years? I can only imagine how this keeps up later on.
