I loved so much about this - the introduction to roller derby, the frustrating mistakes that Astrid makes with her friends and mom (and how she realizes them), and how Astrid is brave by trying something new and really hard. I do wonder about the significance of her leaving the flowers in the end - I hope that doesn't mean that she won't keep working on her friendship with Nicole. As I'm sure many have pointed out, this is a great suggestion for fans of Raina Telgemeier - it's very similar in content and style.
