High School is the revelatory and unique coming-of-age story of Sara and Tegan Quin, identical twins from Calgary, Alberta, growing up in the height of grunge and rave culture in the 90s, well before they became the celebrated musicians and global LGBTQ icons we know today. While grappling with their identity and sexuality, often alone, they also faced academic meltdown, their parents' divorce, and the looming pressure of what might come after high school. Written in alternating chapters from both Tegan's point of view and Sara's, the book is a raw account of the drugs, alcohol, love, music and friendship they explored in their formative years. A transcendent story of first loves and first songs, it captures the tangle of discordant and parallel memories of two sisters who grew up in distinct ways even as they lived just down the hall from one another. This is the origin story of Tegan and Sara.
