The Juvenile War

All adults and young adults are gone from the world. Now its just teens and children under or at the age of sixteen to control the world. There is a scarcity of supplies like food, shelter, water, and gas to run cars since fuel pumps don't work , after it being like this for 3 years now. The young children and teens create gangs, fight over food, territories, and sometimes over people. I guess its kinda like a war.
But as a sixteen year old named Aundre is to take care of his younger brother Rick which is ten, but also his bestfriend Zak is living with him which distracts Aundre from taking care of his brother Rick. After Rick gets tired without getting attention he runs away during the middle of the night which is the most dangerous time to leave your home because the most powerful gang is lurking around, which happens as Rick runs into them in the process of running away. Once Aundre finds out his brother is gone he goes out to look for him.
Does Rick survive?
