I am Number 4

Written by Pittacus Lore

Summary:


John Smith is an alien from the planet Lorien. He was sent to Earth as a child with eight others to escape the invading Mogadorians, who destroyed Lorien. Here, John is protected by a Guardian, Henri, and has developed "legacies", including enhanced strength, speed and agility, telekinesis and the power to transmit plasma light through his hands.
The Mogadorians, led by the Commander, learn about the nine children and come to Earth to find them. The Loriens can only be killed in sequence; Number One through Number Nine, though, and three of them are already dead, with John being Number Four. Knowing this, he and Henri move from a beachside bungalow in Florida to an old farm in Paradise, Ohio, where John befriends conspiracy theorist Sam Goode and a dog which he names Bernie Kosar. He also falls for an amateur photographer, Sarah Hart. Her ex-boyfriend, football player Mark James is a bully who torments both John and Sam.
During the Halloween festival, Mark and his friends chase Sarah and John into the woods, where they try to beat John up. However, he uses his legacies to fend them off and rescue Sarah. Sam witnesses this and how he'd used his legacies. John reveals his true origins to Sam. The next day, Mark's father, the local sheriff, interrogates Henri on John's whereabouts when his son and his friends were attacked.
Henri tells John that too many people are suspicious of them so they have to leave. John refuses because of Sarah. Meanwhile the Mogadorians continue searching for John. Number Six's guardian was killed, and she realizes that the remaining six of the Lorien Garde will have to team up and fight against the Mogadorians. She knows Number Three is dead and that Number Four is being hunted.
The Mogadorians eventually locate John. When John and Sam go to rescue him, they are attacked but manage to fend the Mogadorians off. However, Henri dies after John and Sam escape with some Lorien artifacts. John saves Sarah from a fire, revealing his powers in the process, and they escape to their high school.
There, John, Sarah and Sam are attacked by the Mogadorians, who brought two giant monsters to hunt the trio. They are saved by Number Six and Bernie, who is actually a shapeshifting Chimera sent by John's biological parents to protect him. John and Number Six continue to fight the Mogadorians. They eventually defeat them all, including the Commander.
John leaves after promising to return to Paradise and to Sarah.
