This illustrated gift book of short comics illuminates author Debbie Tung's experience as an introvert in an extrovert's world. Presented in a loose narrative style that can be read front to back or dipped into at one's leisure, the book spans three years of Debbie's life, from the end of college to the present day. In these early years of adulthood, Debbie slowly but finally discovers there is a name for her lifelong need to be alone: she's an introvert. The first half of the book traces Debbie's final year in college: socializing with peers, dating, falling in love (with an extrovert!), moving in, getting married, meeting new people, and simply trying to fit in. The second half looks at her life after graduation: finding a job, learning to live with her new husband, trying to understand social obligations when it comes to the in-laws, and navigating office life. Ultimately, Quiet Girl sends a positive, pro-introvert message: our heroine learns to embrace her introversion and finds ways to thrive in the world while fulfilling her need for quiet.
