I couldn't make it through this entire book without forcing myself to read it. If you look at most narratives, they follow Aristole's plot triangle, which begins with backround information. This book gives you basically no backround information. I can see what the author was going for, which was where the characters develop throughout the story, but it's not done right. It's like starting a movie halfway through, you have no idea what's going on or who anyone is.
It's also very hard to understand what the main character is like. She'll be brave and strong one chapter, and the next be afraid to do anything. This makes it hard to like her, and having likeable characters is an important part of a good book.
The story also moves very slowly, but speeds through the exciting parts. She spends a few chapters talking about walking through some woods, a city, and talking to some people, but only a short amount of time talking about being attacked.
