Study Questions and Answers
1. Why does Natalie feel uncomfortable living alone in this chapter?
She has been reminded of Dawn’s fate—Dawn lived alone and is now missing, with blood found on her floor. That proximity to danger makes Natalie acutely aware of her own vulnerability.
2. What is significant about the blocked call Natalie receives?
The call is silent, just like the calls she received months ago from someone she knew. This suggests that the harassment may not have ended as she believed, potentially linking the past threat to Dawn’s disappearance.
3. Why does Natalie describe texting someone as “a mistake”?
