Existence and Eternal Return

Have you ever had the feeling of seeing a movie and feeling like you've seen it before? Have you ever had the feeling that your life has been dominated by an invisible force? Have you ever had the feeling that you were just a character in a story and that our world was just a model in a drawer in a kid's room? The protagonist of this novel, like you and me, discovers the mutuality between books and reality when reading books, and discovers that we may just be a given character. Will you still do the same thing as the protagonist in the book?
