Now reunited, they must struggle to find the identities they lost, but when the fate of the world is at stake they must band together, and place past rifts behind them, with people as gifted as themselves, to form the Riders, a vigilante group, who are the Earth’s only chance of salvation from evil…but will it be enough for them to survive an enemy they were born to face together?
