In the town of Middling, everyone has a defined role—except Finn. Lacking a title or talent, he discovers a tear in reality that leads to the Cast Vault, a crossroads of story kingdoms. Labeled a "Plot Hole" by a rigid Editor, Finn faces deletion for being a narrative inconsistency. Instead of vanishing, he uses logic to disrupt tired tropes and returns to his unfinished home to face the Deleter, proving that being a "work in progress" is a destiny of its own.
