And stopped. And realized that somewhere in that [sentence] was the kid I was really trying to find."^[11] After several years of gestation, Chbosky began researching and writing The Perks of Being a Wallflower, an epistolary novel that follows the intellectual and emotional maturation of a teenager who uses the alias Charlie over the course of his first year of high school.
