Make a case for each of these characters as the novel’s antagonist or villain: Edward, Claire, Paul, and Amber. Then, make a case for each as the novel’s protagonist—that is, the emotional and moral hero.

Research the psychology of imaginary friends. Why does Amber rely on Jo? Why does Jo leave Amber in the hospital? Is it possible that Claire does not exist?

Paul is perhaps the most complex and least understood character in the novel. Why does he buy the diary? Why does he purchase the lingerie? Do you believe his story about the fall his mother takes? How does his profession help define his character? Compare Paul and Edward—what does they reveal about Amber’s emotional make-up?
