Yes, I know that's hideously clumsy.
So was mine. I found the following that explains it better than I can:
Authorial Intrusion is a literary device where the author intentionally breaks from the narrative and addresses the reader directly. Used correctly, this device can create a relationship between the author and the reader adding an additional layer to the story. Used incorrectly, it becomes an annoying nuisance.
In the classics, authorial intrusion was more common. Hawthorn in The Scarlet Letter, Fitzgerald in The Great Gatsby, and Hugo in Les Misérables are a few examples. (These intrusions also exist in plays as an aside or other forms of breaking the 4th wall.)
In these examples, the authors would interject commentary about a social or political issue into the prose. These comments were not intended to come from the POV character and often were used to illustrate how a character's or society's views were mistaken. These interjections could be a short as a phrase, or, in the case of Victor Hugo, could go on for pages. Usually, these were related to the theme or were otherwise politically motivated.
Authorial Intrusion in contemporary literature is more commonly used for comedic effect or to portray the author as a character. Books like A Series of Unfortunate Events by Lemony Snicket uses frequent Authorial Intrusion. On the first page, Snicket begins the story by addressing the reader directly.
If you are interested in stories with happy endings, you would be better off reading some other book. … I'm sorry to tell you this, but that's how the story goes.
Snicket pops in and out the narration frequently, either to comment on the direness of the situation or to explain the meaning of a difficult word. This creates the illusion of Snicket, not as an invisible author, but as a living person who has discovered this story and is sharing it as a warning to others.
In most stories, the author is invisible, intent on creating an immersive experience for the reader.
If you are writing in 1st person POV or deep 3rd, you shouldn't use authorial intrusion. (If anyone has an example of this working, I want to see it.) You will break the illusion of immersion. In these POV's, there is no omniscient narrator who is allowed to interject his/her thoughts into the story. Every word that is written must come from the POV character's thoughts.
