At night, the Diesel Mine dreamed. It counted itself and found nothing it could not name. It made lists and erased them. It kept trying to be tidy.

The story follows a group of female protagonists trapped within a shifting, malevolent educational institution that exists outside of normal reality. In this final chapter, the stakes are raised as the "Lost Girls" must uncover the ultimate truth behind the school’s existence while evading increasingly grotesque and lethal entities.
