The books' format of narration is as if in a mockumentary, sometimes with characters describing the situation, their feelings, opinions and what-nots in a talking head style as if expressing their internal monologues to a camera during an interview, similar to documentaries and reality TVs with such portrayals, and those internal monologues are included into the story like a post-script.
