Pittacus Lore

Pittacus Lore is a pen name, the collective byline of James Frey, Jobie Hughes, and, on earlier volumes, Greg Boose. Under that name they wrote the Lorien Legacies, a young adult science fiction series that opens with I Am Number Four and continues through The Power of Six, The Rise of Nine, The Fall of Five, and The Fate of Ten. The Lost Files spin-off, beginning with Six's Legacy, runs alongside the main series.
