Astrid, a girl who's whole life has been spent in the company of Nicole, watches a roller derby and becomes enhanced, and then signs up for derby camp, once in her life without Nicole. There she meets Zoey, a headstrong young girl with bright hair and an attitude just as bright. Astrid learns about the mini bout, and fiercely wants to be a jammer in it, even if it means using free time to train. Sadly, Zoey is picked instead. The day of the bout, Astrid figures out her derby name; Asteroid! She pulls through during the derby, even if she twists her ankle in the process. The twists and turns she experiences on the track and in real life are true, and she is an amazing person. Five out of five stars, really wonderful.
