"Fifty cents? Who even carries around quarters? Who's going to have that on hand if it's an emergency? The more I think about it, the more I think this is a real health issue. The school can buy brand-new uniforms for the football team, but they're charging us fifty cents for tampons that they can't even bother restocking? How are we supposed to focus on school if we're worried about leaking through our pants?"

If you have never been a girl in middle or high school, you have no understanding of the angst felt by Sasha Chen on her first day at Hazelton High. Being new is tough enough: trying to navigate hallways, notice all the posted invitations to join teams, and keep a low profile makes her day trying. 

On her second day, she notices that the response to her by other students is amped up. They are laughing, and looking at her with revulsion. Luckily three girls who are already friends (Abby, Brit and Christine) notice, and take her under their protection to the washroom where they tell her period has leaked through her white pants. To add to the embarrassment already felt by Sasha, there are no period protection products available for purchase in the washroom. The machines are empty. 

Abby is furious and makes it her mission to find out why, and to make a case for free feminine products for the half of the student body that experiences monthly periods. The principal puts no stock in her complaint, suggesting that she deal with her own 'little problem'. The girls decide they will do something more about the problem. Abby carries their protest a bit too far, and causes a rift with the group. 

Using a red-hued tone for the graphic artwork is empowering for those who will read this very accomplished novel. Perhaps it will give them impetus to have a say when they know that things need to change. Together they can try to change what is happening where they are, and for others experiencing the same injustice. The four girls are unique in height, color, race and body type. They share opinions, difficulties, expectations, and a clear goal. Their friendship remains strong; although each is dealing with issues of her own.

Frank, emotional and exploring a subject rarely discussed in young adult literature, their story has power and should be read by many. Awkward for many, but necessary for all.
