Almost every book—at least, every good book—has a purpose within its pages. There’s a reason it was written. There’s a reason the story is compelling or a reason the story has meaning to at least one person. It’s the nature of many great stories for their purposes to shift and change between one reader and another. One person may read a story and find that it teaches them about love and loss while another reads it and finds lessons in empathy. Neither of these readers is wrong in this, even though there is almost definitely an original intent in the work that was behind the author’s first writing.
