Charlie, the wallflower of the title, goes through a veritable bath of bathos in his 10th grade year, 1991. The novel is formatted as a series of letters to an unnamed "friend," the first of which reveals the suicide of Charlie's pal Michael. Charlie's response--valid enough--is to cry. The crying soon gets out of hand, though--in subsequent letters, his father, his aunt, his sister and his sister's boyfriend all become lachrymose. Charlie has the usual dire adolescent problems--sex, drugs, the thuggish football team--and they perplex him in the usual teen TV ways.

Into these standard teenage issues Chbosky infuses a droning insistence on Charlie's supersensitive disposition. Charlie's English teacher and others have a disconcerting tendency to rhapsodize over Charlie's giftedness, which seems to consist of Charlie's unquestioning assimilation of the teacher's taste in books. In the end we learn the root of Charlie's psychological problems, and we confront, with him, the coming rigors of 11th grade, ever hopeful that he'll find a suitable girlfriend and increase his vocabulary.
