The Bookshelf discussion

I recently became a full-time high school teacher due to the unexpected resignation of a good and close co-worker. Her room became mine and I inherited many things in it including the rather large classroom library. I had rearranged the room to suit my needs. An aspect of this arrangement is that there are 3 or 4 copies of this novel that are quite visible when one walks through my door. I had never read this novel, but have told myself that I should because the cover looked interesting. The other day, a co-worker of mine came by my room and stopped to see that I had owned copies of this book and was displaying them in my classroom. She asked me one question that piqued my interest immediately: "Do you think that is appropriate to have here?" I informed her that I would have to read it in order to answer her question.
