Just read: Redshirts ( John Scalzi )

The novel satirizes a (badly written) science fiction TV show. Over time, the protagonist and some others become aware that they are they are within that TV show, and that they must avoid The Narrative. The Narrative is most prevalent around the bridge personnel of the spaceship. Unfortunately for the protagonist and their team, the bridge crew members carry plot armor, a luxury not awarded to normal crew.

The novel is an amusing read, with a fun premise and good follow-through. I also liked the coda where the situation is looked at from the perspective of the (bad) TV show writer and other people in the story.
