I Am Number Four - Nine teens are sent from their home planet, Lorien, to escape the Mogadarians, a vicious species bent on destroying them.

Among the Hidden - Luke is one of the shadow children, a third child forbidden by the Population Police. He's lived his entire life in hiding, and now, with a new housing development replacing the woods next to his family's farm, he is no longer even allowed to go outside.
Double Identity - As Bethany approaches her thirteenth birthday, her parents begin acting more oddly than usual: Her mother cries constantly, and her father barely lets Bethany out of his sight.

But mostly it's just frustrating, being a kid trapped in an adult world.
Voyagers: Earth is in danger! The only things that can save our planet are six essential elements scattered throughout the galaxy. And it is up to the Voyagers—a team of four kids and an alien—to gather them all and return to Earth.
