The premise of the book can easily be countered. I don't think it's too political for AP English. However, I think there are many better choices.
"I think there are many better choices."
I agree!! What ever happened to teaching the classics, i.e., Shakespeare, Dickens, Bronte, Austen, Hardy, Eliot?? These are more suited to an AP English class than any of the 20th Century crapola that tries to pass itself off as great literature!
If they are going to assign science fiction in advanced placement courses, start with Heinlein, Asimov, and Clarke.
