Everyone has gathered outside at night to watch an Asteroid hit the moon. But an unpredicted event insues: The Asteroid knocks the moon out of orbit, resulting in cataclysmic storms and natural disasters.
After the first monsoon, people were raiding stores and supermarkets. Miranda's mom was among the chaos at the supermarket taking all she could carry and packing it into the car.
Since food was scarce, everyone in Miranda's high school was getting only a Pb&J sandwich for lunch. Eventually, people started to skip school altogether.
Miranda had made up her mind to kill herself, because it was winter and food was running out everywhere. It was one less person to feed in her family, as far as she could tell.
Miranda found out that someone was handing out food and decided against suicide. Instead, she brought food back home and everything worked out fine.
