The ending is hopeful:

Deborah is with me still, and always will be. Sometimes at night, I talk with her in my dreams. When I see her there, she is always six years old.”
-- Sandra (chapter 32)

Importance: These are the final words of Sandra's autobiography, and she ended by saying that her journey to accept Deborah's death brought her to be open to people of all cultures rather than to hate.
