Once taken in by Batman and cast out at twelve, a former sidekick survives into adulthood by abandoning everything they were taught. Now twenty-one, unrecognizable and hardened, they live a grim life as a hired killer—far removed from the hero they once tried to be. Cut off from the Batfamily, drowning in stress and regret, their past feels buried for good… until a vigilante recognizes them, forcing old wounds and unfinished truths back into the light.
