Summary
Analysis
Joana closes her eyes but can still see the chaos and tragedy replaying behind them—thousands of people dying and drowning. It is difficult for her, knowing “so many people needed my help. And now I could do nothing.” Her chapter ends with the thought, “Guilt is a hunter. I was its hostage.”
As someone who has been carrying guilt for surviving tragedy for the past four years, Joana unsurprisingly is unable to deal with the guilt of knowing people are dying around her while she is unable to help them.
