Lorien Legacies is a series of young adult science fiction books, written by James Frey[1], Jobie Hughes, and formerly, Greg Boose, under the collective pseudonym Pittacus Lore.
The series follow the story of nine human-looking aliens brought to Earth when they were six years old. Their purpose is to grow into their powers and return to their planet, Lorien, and get it back from the evil Mogadorians. The teenagers have been protected by a charm, which only allows them to be killed in a set order, and by non-gifted guardians called Cêpan.
