What if aliens came to Earth and wanted all the power? Would we even know? Jenny O’Neil experiences exactly this. While sitting in her 9th-grade class, the power goes out. At first, everything seems to be okay. Her father takes her home, and school is canceled. For days, she sits at home drawing and working on homework the teachers still assigned to her. But on the fourth day, a soldier shows up in fatigues. He takes their batteries. That night, her town is attacked.
