"Sadie Wen is perfect on paper: school captain, valedictorian, and a 'pleasure to have in class.' It's not easy, but she has a trick to keep her model-student smile plastered on her face at all times: she channels all her frustrations into her email drafts. She'd never send them of course--she'd rather die than hurt anyone's feelings--but it's a relief to let loose on her power-hungry English teacher or a freeloading classmate taking credit for Sadie's work. ... Sadie doesn't have to hold back in her emails, because nobody will ever read them--that is, until they're accidentally sent out"-- Provided by publisher.
