Lorien Legacies

''Lorien Legacies'' is a series of young adult science fiction books, written by James Frey, Jobie Hughes, and formerly, Greg Boose, under the collective pseudonym Pittacus Lore.

The title of the series refers to the characters' home planet of Lorien, which itself is likely a reference to the Elf realm of Lórien in the ''Lord of the Rings'' book series by J. R. R. Tolkien, though this has never been confirmed. Provided by Wikipedia
