Question: can you break the fourth wall in a book

Answer: Yes, The method of breaking the fourth wall in literature is typically referred to as metafiction. Metafiction genre occurs when a character within a literary work acknowledges the reality that they are in fact a fictitious being. The use of the fourth wall in literature can be traced back as far as The Canterbury Tales and Don Quixote. However, it was popularized in the early 20 century during the Post-Modern literary movement. Artists like Virginia Woolf in To the Lighthouse and Kurt Vonnegut in Breakfast of Champions used the genre to question the accepted knowledge and sources of the culture. The use of metafiction or breaking the fourth wall in literature varies from that on stage in that the experience is not communal but personal to the reader and develops a self-consciousness within the character/reader relationship that works to build trust and expand thought. This does not involve acknowledgment of a character's fictive nature. Breaking the fourth wall in literature is not always metafiction. Modern examples of breaking the fourth wall include Ada Palmer's Terra Ignota and William Goldman's The Princess Bride.
