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.
Gail Carson LevineHe loved me. He'd loved me as long as he he'd known me! I hadn't loved him as long perhaps, but now I loved him equally well, or better. I loved his laugh, his handwriting, his steady gaze, his honorableness, his freckles, his appreciation of my jokes, his hands, his determination that I should know the worst of him. And, most of all, shameful though it might be, I loved his love for me.
