Why do you keep reading a book? Usually to find out what happens. Why do you give up and stop reading it? There may be lots of reasons. But often the answer is you don't care what happens. So what makes the difference between caring and not caring? The author's cruelty. And the reader's sympathy...it takes a mean author to write a good story.

I ran to the door to our street, opened it, and called out into the night, "I shan't marry the prince." I turned back into the hall and ran to Char and threw my arms about his neck. "I shan't marry you." I kissed his cheek. He was safe from me.
