Query: Mature Readers Will Enjoy The Perks

Last week, I was moved when I saw Mr. Chbosky at the IRA conference in Indy. He spoke beautifully about the state of teenagers today. Therefore, I bought his book and was intrigued by the sensitivity illustrated in his character, Charlie. I am, however, compelled to advise parents and teachers to read this book before reccomending it to their children. It is a mature novel.None of the sexuality issues, drug use, or language are gratuitious. In fact, they are needed for the honesty in the novel. I would caution that this novel should be used in high school and not in middle school. It would be more appropriate for that age group. I am not a censor. I loved the book. I encourage mature readers to embrace the touching tale of Charlie, Patrick, Sam and all the others.
