Seventeen-year-old Sadie Wen is perfect on paper: school captain, valedictorian, and a pleasure to have in class. It's a reputation she's fought hard to earn at the highly prestigious Woodvale Academy, and one she's determined to maintain until graduation.
The trick to keeping her model-student-smile plastered on her face at all times? She channels all her petty frustrations into her email drafts. One for the math teacher who refused to round her eighty-nine-point-nine percent up to ninety; one for the girl who blatantly copied her science project and took the credit for it. But most of her vehemently-worded emails are for her smug, infuriating co-captain, Julius Gong, who's been the sharpest thorn in her side ever since they were kids.
Unlike in the classroom, Sadie doesn't have to hold back in her emails, because nobody will ever read them ... that is, until someone sends them out.
Overnight, Sadie's carefully crafted, conflict-free life is turned upside down. As old grudges resurface, new tensions grow, and her decade-long rivalry with Julius becomes the center of attention, the school forces the two captains to work together across a series of projects in a show of camaraderie. But amidst the chaos, Sadie finds herself increasingly surprised--by the boy she's sworn to hate, the classmates she thought she knew, and her own heart.
