I enjoy this book, it's easy for me to fall back into its world when I reread it. I like Auden, her growth through the book is great. The side characters in this book are definitely some of my favorite. 
One thing that I'm not a huge fan of from this book is Audens parents.

I like where things ended with Audens Mom, she was trying to be better and do better for her relationship with her daughter, her mother obviously would've done alot for her, even if she was pretty rough at the beginning. That Dad on the other hand, I don't think him coming back and choosing family over himself fits. I get one of the points of this book is people change, but to me the dad coming back and looking after the baby isn't believable, he wouldn't have taken the initiative unless he was specifically told by Auden that's how he could fix thier relationship. He was just Selfish-Selfish. </Spoilers>
