After centuries of living in this prison, a reader with a completely unique sensibility started reading the book. She was interpreting the novel in a thoroughly new way. No longer was he the unwavering paladin. She saw him as a tragic hero, harbouring ambivalent thoughts and feelings about himself and life.
Although he never could escape the novel or change any of its words, once in while a reader would come who would give him new meaning, and he never felt imprisoned again.
