There’s really not much information here to help us answer the question. Are you looking for general questions that could apply to any book? Are you looking for questions with regard to a specific book? Why do you need discussion starters? Is this for a school project? Is it for a book discussion group? Something else?
What was the book? What was it about? Did you like it/learn anything from it? Would you recommend it to someone else? Why or why not? How does it compare to other books of this type that you have read? Why type of book (genre) does it fit in? Why did you read it? How did you hear about it? Do you think it should be made into a movie (if it hasn’t already been made into one)? Why or why not? Is it plot driven, character driven or language driven? Whatever drives the book, how would you characterize the driver? Did the author seem to know what they were talking about? Was it believable? Was it fantastic? What literary devices did the author use to get readers to see the underlying meaning of the book? How did they work? What did they tell you?
I mean, these things are all pretty obvious (unless, maybe you are in middle school—well, maybe ninth grade). If you use any of these questions, you must attribute them to me. You may not claim them as your own. That would be plagiarism. Even if you change them slightly, you must still attribute them to me. To do otherwise would be dishonest and underhanded. You realize that by asking this question, you have pretty much eliminated any chance of coming up with questions of your own, right? If you are working on a project for professional purposes, you must especially attribute the ideas to me, and if you make any money on this, the honorable thing to do would be to offer me royalties. Intellectual property, you know. If you don’t do these things, and I ever find out that you have used my ideas, I can sue you. So make sure it doesn’t get on the internet. I will be checking.
