Mara Deebly, in need of a team sport to prove she can be a team player, joins the football team and unintentionally starts a feminist movement in her highschool. Much to her and the boys' disgust, several other girls feel inspired by her decision and follow her onto the football team, where Mara get's lumped in with girls she feels are frilly, weak, and won't take the game seriously. As she tries to set herself apart from her new teammates, she and the other girls experience bullying and unfairness by even people on the team she had thought were her friends. Although I was concerned by Mara's anti-woman mindset at the beginning of the book, I found it to be a very enjoyable story about growth, changing stereotypes, and learning to find strength in things that aren't masculine. This book engages with themes such as misogyny, bullying, and female empowerment.
