There are many pivotal scenes in this book. Some are exciting or terrifying, and some are quieter. As a class, make a list of the pivotal scenes. Then have each student select one of these scenes and write an essay describing its significance. What purpose does this scene serve in the greater framework of the book? What changes happen in the course of this scene? How does it move the story forward? What does it reveal about the characters involved? Be sure to cite specifics from the text. Break students into pairs and have them share their essays, revising their work based on peer feedback.
