I love sarah dessen's books. They are like a guilty pleasure of mine. I know that in the end things are going to work out, and so when I want something to read that I know I'll be happy with I tend to choose her books. 
 I also find that they are very accessible. They deal with real issues, but i think that both people who have, and haven't experienced them can read her books and understand the characters extremely well. 
 I read some books that I know will make me sad, and they will usually get a very high rating because they are beautiful and hurt me. Dessen's books aren't quite like this. Some books are very raw, and you have to be in a certain place to read them. But the beauty of her books is that I believe they can introduce people to issues they hadn't really thought about before, in a setting that's comfortable for them. 
 The plot of this book was fun, a little different because the main character was 15, rather than the 17-18 I'm used to. Her mother is a fitness instructor, and despite having lost a lot of weight she still feels so much pressure to fit in. The supporting cast were great as usual. This is a good book to get people thinking about body image and what it means to be a confident person.
