Lexa’s quest to retrieve the ship and track down the Garde has her cross paths with an ally of Pittacus Lore, come under fire from both the FBI and the Mogs, and team up with a headstrong teenager from Paradise, Ohio, by the name of Mark James. To get her secret weapon, Lexa will do whatever it takes. But as the Mogadorians begin their invasion, will it be enough to help save the Garde—and the world?
