At the beginning of this book, aliens invaded Earth. They used ships that would take people into it and then kill them if they didn't make it it through certain obstacles. The people who did make it could then control the ship. After a few days more aliens called the Micros invaded. They used huge alien robots that were nearly impenetrable. The armies of the world couldn't beat them until they found out lasers.
