A fast-paced coming of age comic in the vein of Raina Telgemeier. Astrid's mom takes her and her best friend Nicole to watch a roller derby game in a rink in Portland and Astrid immediately falls in love. Her best friend, not so much. Astrid signs up for a roller derby summer camp and discovers how much work it is to master a tough, dangerous sport. Meanwhile she begins to feel abandoned by Nicole who chose to attend a Dance camp instead. What starts as a story of rivalry becomes instead a tale of how people sometimes grow apart as their interests change and mature.
