The power of Six

This sci-fi sequel follows a group of extraordinary, superpowered alien teens hiding on Earth from a ruthless alien race called the Mogadorians who destroyed their home planet. While the first book focused mostly on Number Four (John), this installment expands the story to show the perspective of Number Seven (Marina), who is hiding in a convent in Spain. As the deadly Mogadorians close in on them, the scattered teens must desperately try to find each other, combine their unique abilities, and fight back before they are hunted down one by one.
