I am surprised at how much I liked this. Normally I don't like books in which I don't like the main character but this is the exception. I love that the author showed how disordered the main character's thinking was with cross outs and by putting the calorie count of food every time it came up in the main character's life. The main character came off as cold, which worked for the concept of 'wintergirls'. Also, I think her coldness was a way of showing how far removed she had become from her real life and how the mental illness had taken over her entire personality. 
 My main issue is that I didn't follow the storyline in terms of how Lia randomly attached herself to a guy. Plus, I also think the ending felt rushed and we went from bleak to hopeful a little bit too fast. I would have liked to have seen some conclusion, or at least some closure to her issues with her stepmother, rather than just being told that they were all attending therapy. Other than that, this is a haunting read that will make you think, it might also leave you feeling a little bit cold inside.
