Either her editor needed to do a better job, or her ghostwriter needs to be fired. The writing is pretty awful (though not quite Stephanie Meyers awful), disjointed and filled with slang. Her sentences frequently contradict each other, even within the same paragraph!
Despite the disjointed nature of the narrative, it was definitely interesting. How many 13 year olds move to a foreign country by themselves for boarding school? I have a little experience with Russian ballet teachers, so hats off to Loughman for getting through that kind of education with minimal bitterness. I'm less pleased that she felt she just had to take the abuse and keep quiet, but gratified that that type of attitude did not persist. She stood up for herself, often in glorious outbursts of rage, which kept her story from getting to pitiful/frustrating.
This is really more like a two & a half star rating: the writing was bad enough to knock it to a two but the story itself was engaging enough to merit a three.
