Dear Mr. Cornwell, I am a Sophmore at Napa High School in Napa, California and a big fan of your books. I recently read your book Crackdown for a project in my english class and enjoyed it a lot. For the oral presentation we have to tell what qualities make a book great. I was wondering if you could give me your opinion on what qualities make a book great. I understand you are probably busy, but I would appreciate it if you could write me back and let me know. Thanks for your time. -David McGraw
