As a strong proponent of the Death of the Author, I sincerely believe that any interpretation of a text is valid, as long as it can be justified by reference to that text. So, what’s the wackiest, most out-there reading of the book you can reasonably support? Are there indications that it’s all taking place in a holographic simulation in the future? Is it all really an allegory for the journey of Osiris through the underworld? You have as much authority here as I do: go wild.
