I am a fan of graphic novels and this one was absolutely fantastic.  In particular I liked having the chance to read about roller derby.  I didn't know what roller derby was and now I am thinking I might even want to try it myself.  I could understand Astrid when she and Nicole had problems.  She is upset that Nicole chose Rachel over her.  If you liked "Smile" and "Sisters" you will like this book as well because like those books are graphic novels about a character going through hard times.  Readers should know that there is a bit of bullying. Nicole teases Astrid about her name.  There are a lot of middle school friendship problems.  I really liked this book and would recommend it to realistic fiction readers and graphic novel readers.
