Before the indie-pop duo Tegan and Sara took the world by storm, Tegan and Sara Quin were identical twins trying to find their place in a new home and new school. From first crushes to the perils of puberty, surviving junior high is something the sisters plan to face side-by-side, just like they always have. But growing up also means growing apart, as Tegan and Sara make different friends and take separate paths to understanding their queerness. For the first time ever, they ask who one sister is without the other. Set in the present-day, this fictionalized autobiography offers a glimpse at Tegan and Sara before they became icons, exploring their shifting sisterhood, their own experiences coming out, and the first steps of their musical journey.
