She's the school captain, valedictorian, and a "pleasure to have in class". Her secret? She channels all her petty frustrations into her email drafts. 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. Sadie doesn't have to hold back in her emails, because nobody will ever read them... that is, until someone sends them out.
