After facing off with the Mogadorian ruler and almost being annihilated, the Garde know they are drastically unprepared and hopelessly outgunned.

To defeat their enemy, the Garde must master their Legacies and learn to work together as a team. More importantly, they’ll have to discover the truth about the Elders and their plan for the Loric survivors. And when the Garde receive a sign from Number Five—a crop circle in the shape of a Loric symbol—they know they are so close to being reunited. But could it be a trap? Time is running out, and the only thing they know for certain is that they have to get to Five before it’s too late. The Garde may have lost battles, but they will not lose this war.
