In rural Ohio, friendships and a beautiful girl prove distracting to a fifteen-year-old who has hidden on Earth for ten years waiting to develop the Legacies, or powers, he will need to rejoin the other six surviving Garde members and fight the Mogadorians who destroyed their planet, Lorien.

After facing off with the Mogardorian ruler and almost being annihilated, the Garde go into hiding. They must learn to master their Legacies and learn to work together as a team. When they receive a sign from Number Five -- a crop circle the shape of a Loric symbol -- they know they are close to being reunited. But could it be a trap? Time is running out and they only thing they know for certain is that they have to get to five before it's too...

The Garde didn?t start this war, but they are determined to end it and with the fate of the Earth up in the air, they must battle the Mogadorians one last time.
