Writer´s karma

Paulo Swan is a conflicted writer. One day, he stepps foot into Lorian bookstore. After that, mysterious things start to happen.
But the most peculiar is when his doorbell rings. No one is there, and he is no longer in York. He is in his fictional world Wilox.
He is told that the only way to return to his world is if he knows the correct answer to why his story matters so much to him. Otherwise, he will remain trapped in his own work forever.
