Cade barely managed to survive the duel with the Hydra Alpha-- but the Games are far from over. By order of their cruel overlord, Abaddon, Cade and his friends are sent off to war against the Greys, a humanoid race who have far surpassed humans in technology on their home planet. This attempt to move up the leaderboard... and leads Cade to a game-changing revelation: The Pantheon, the millennia-old alien masterminds behind the Games, have a weakness. Now Cade has one chance to end their tyranny forever... or the survival of Earth itself will be forfeit. -- adapted from jacket
