Nine aliens arrived on Earth. They came from the planet Lorien and are being hunted. They can only be killed in numerical order because they have a spell cast on them.The first three have been killed by the Mogadorians. Number Four is next. Number Four has taken the identity of John.
Number Four is starting over again. This time will be different though. His name will be John and he will have actual friends. John needs to be careful. The Mogadorians are on his trail and he can't do anything that will draw attention to himself. That is a harder task than he expected. John is developing powers that are strengthened by emotion. It's hard to keep them under control when kids at school are trying to get him angry. John keeps his temper though, and he makes friends. Life is a lot better when you have people around you, even if you are on the run.
One mistake that John makes ruins everything. The Mogadorians find him and his friends. There is nothing they can do but fight. They have to kill every last one of them. It's a huge task, and John isn't ready for it, but he doesn't have a choice. Will John and his friends make it out of the battle alive, or will lives be lost?
