It has been over a year since the invasion of Earth was thwarted in Pittacus Lore’s United as One. But in order to win, our alien allies known as the Garde unleashed their Loric energy that spread throughout the globe. Now human teenagers have begun to develop incredible powers of their own, known as Legacies. To help these incredible and potentially dangerous individuals—and put the world at ease—the Garde have created an academy where they can train this new generation to control their powers and hopefully one day help mankind. But not everyone thinks that’s the best use of their talents. And the teens may need to use their Legacies sooner than they ever imagined.
