Plea for Help

I have been asked to compile a list of must reads for high school honor students. This list will be used as a resource for teachers to consult when compiling their summer reading lists. Since I have spent most of my career in elementary and middle school classrooms, I’m not sure that I am the person for the job, but I know that some of you out there in the blogosphere are high school teachers and you will share your wisdom with me. Please tell me what you think. What books (both classic and contemporary) do you feel are must reads for high school students?
