The Perks of Being a Wallflower is a young adult coming-of-age novel by American writer Stephen Chbosky. Set in the early 1990s, the novel follows Charlie, an introverted observing teenager, through his freshman year of high school in a Pittsburgh suburb. The novel details Charlie's unconventional style of thinking as he navigates between the worlds of adolescence and adulthood, and attempts to deal with poignant questions spurred by his interactions with both his friends and family.

The story is presented in a series of letters that Charlie writes to an unnamed friend, and these documents chronicle his trials, tribulations, and triumphs as he goes through his first year of high school. Charlie's journey is one of self-discovery and growth, and the book deftly explores themes of mental health, romance, and the intense emotions associated with the teenage years. Through Charlie's experiences, the reader is drawn into the tumultuous world of first dates, family dramas, and new friendships, as well as the more serious issues of sex, drugs, and personal loss.
