Growing up is hard enough, but as Leigh and her friends are about to discover, things get real when our bodies begin changing! Realizing that their classmates are just as confused about menstruation as they were before their families helped them understand what it's all about, Leigh and her friends - Ada, Lena, and Sandi, form The Period Posse, a group to research, support, and educate their peers about the journey through menstruation. Together, the young change-makers advocate for improved menstrual education in schools, but when they're met with challenges from administration, will they give up championing for other girls to embrace the changes in their bodies and raise awareness, or continue fighting for menstrual equality for all? The Period Posse: Embracing Change and Empowering Others is an inspiring tale of friendship, growth, and the power of young voices to embrace knowledge, break stigmas, and join the movement for positive change!
