Injured, on the run, and without a friend in the world, Lady Vengeance returns to Cobalt City. Stardust can't be sure which is more dangerous-the murderous vigilante chasing her, the dark secret which grants Lady Vengeance her powers, or the threat this dangerously alluring bad-girl poses to his family life. Is it a team-up or a free-for-all? And is Cobalt City big enough to contain the sheer firepower all sides are willing to unleash to assure victory?
