The Perks of Being a Wallflower (novel)
In the book, the English teacher gives Charlie books to read that he thought he would enjoy. One of these books is "The Catcher in the Rye" by J. D. Salinger, which Chbosky says was an inspiration for him to write "The Perks of Being a Wallflower". Also some music titles had inspired him, for example ''Asleep" from "The Smiths".
