I need help writing a story within a story. One of my main characters is going to read aloud from a fairytale book to a few other main characters. First, are there any punctuation rules i should know about, such as putting words in italics, or double quoting? Second, this fairytale stars the main characters of my novel, and was written a couple of centurys ago. The whole moral of this novel is that you make your own fate and nobody can decide it for you, therefore, the novel will end differently than the fairytale does. My question is, how do I make both stories interesting, with the same setting, characters, and plot, but with different endings? Please, help!
